ISO/IEC CD2 18023-1 — SEDRIS functional specification
The table of contents contained in Table 5.1 lists each of the data types used by SEDRIS.
This clause specifies the fundamental data types used within SEDRIS to specify the various DRM class instances that are to be represented. Such data types are composed of basic and constructed fundamental data types. The DRM class specifications contained in 6.3 DRM class specifications use the fundamental data types as the building blocks for creating SEDRIS objects. The API specified in 7 Application program interface (API) uses both the data types and data class specifications to pass information between the application program and the SEDRIS transmittal.
More complex data types are formed from simple data types. These simple data types represent single pieces of information such as numbers, alphanumeric characters including strings of these, Booleans and other individual data constructs.
There are two basic categories of numbers that are represented in the fundamental data types. These are integer numbers and floating point numbers.
Several data types for integer numbers are provided. There are both general integer and non-negative integer data types. These are intended to correspond to signed and unsigned integer data types in programming languages. The following represent the three general integer data types:
Byte
Short_Integer
Integer
The following are the corresponding non-negative integer data types:
Byte_Unsigned
Short_Integer_Unsigned
Integer_Unsigned
The following are the corresponding positive integer data types:
Byte_Positive
Short_Integer_Positive
Integer_Positive
All implementations that conform to this standard shall support at least the minimum range specified in Table 5.2.

There is one numeric data type specified in 2.[I18025] that is used in this standard:
EDCS_Integer
This data type is equivalent to the Integer data type specified above.
There are two precisions of floating point numbers specified as fundamental data types:
Float
Long_Float
These correspond to the single and double precision floating point types specified by IEC 60559:1989, Binary floating-point arithmetic for microprocessor systems (see 2.[IEC60559]). The specific values for POSITIVE_INFINITY and NEGATIVE_INFINITY shall be supported. However, implementations on architectures that support other floating point representations are allowed and shall support POSITIVE_INFINITY and NEGATIVE_INFINITY as provided in those floating point representations.
Alphanumeric characters are encoded as UTF-8 as specified in ISO/IEC 10646-1 (otherwise known as Unicode—see 2.[I10646-1]). UTF-8 supports Latin characters as specified in ISO/IEC 646 but also has the ability of representing international characters. Each character is comprised of 1 through 6 bytes as specified in ISO/IEC 10646-1. Hence an abstract character is of variable length. A string is a list of such characters along with codes that specify how the string is to be interpreted (see 5.3.3.278).
The fundamental data type for representing characters is:
Character
The String data type is not a basic fundamental data type. Instead, it is a structured fundamental data type as specified in 5.3.3.278 String.
Enumerated data types are fundamental data types whose values are specified from an ordered list of names. The names are assigned numbers whose values indicate the position within the ordered list. It is these numbers that are actually manipulated by the implementation.
The enumerated data types that are supported by SEDRIS are specified below.
This data type is used to specify the mode in which a SEDRIS transmittal can be accessed. The supported access modes are shown in Table 5.3:

Assume an image is displayed in a Cartesian 2D space with the positive X axis pointing right, and the positive Y axis pointing up, as shown in Figure 5.1. Further, assume an image of size W×H in this 2D space has W image elements in X direction and H image elements in the Y direction.
EXAMPLE A scan direction of RIGHT_UP means that the image data is stored such that the first image element in memory corresponds to the (0 0) coordinate of this 2D space, and the next image elements should be displayed on the positively increasing X axis (the minor scan), until W image elements are displayed (W 0). The next image element will correspond to the (0 1) coordinate of the 2D space. Once the image element (W 1) is reached, the scan direction will continue to move from bottom to top on the positively increasing Y axis, for each successive scan line, until H lines have been accessed.

Selection data types are similar to enumerated data types but do not form a closed end set of entries. Selection data types are all specified to be of type Short_Integer but with specific meanings attached to each value. The set of selections can be augmented by assigning meanings to additional values. Standardization of additional meanings may occur through amendment to this standard or through registration. Selection data types are otherwise processed in the same manner as enumerated data types.
Standard meanings are assigned to positive values from 1 through 1000. Registered meanings shall be assigned to values above 1000. Standard names for the meanings are specified for clarity. Such names are presented below in upper case.
Non-standard meanings provided by an implementation shall be assigned to negative values. Use of such non-standard meanings in a transmittal indicates that that transmittal does not conform to this part of ISO/IEC 18023. These values are made available solely to test new concepts prior to standardization or registration.

This data specifies the role of the responsible party and is specified in ISO 19115 (see [I19115]).
This data type specifies how colour is applied to an object. The various methods are applied as follows:
Distance blend colour is used to model the distortion of colour due to distance from the viewer. (For instance, mountains in the distance appear to be tinted blue, an effect that increases with increasing distance as long as the mountains are still visible.) This is applicable mainly to objects organized by <DRM Distance Level Of Detail Data> (i.e., distance from the viewer) in level of detail related aggregations, since the distance that the object is visible shall be finite. The equation to determine the desired component of the final displayed colour is:
C = PCC*((x-y)/y) + DBCC×(x/y)
where
x is the distance to the object.
y is the total distance that the object is visible.
PCC is the colour of the PRIMARY_COLOUR <DRM Colour> component.
DBCC is the colour of the DISTANCE_BLEND_COLOUR <DRM Colour> component.
Distance blend colour dominates more as viewing distance increases, while primary colour dominates more as viewing distance decreases.
Image blend colour helps determine the appearance of an object that has both a <DRM Colour> and an <DRM Image Mapping Function> whose image_mapping_method is set to blending.
Valid values are described in Table 5.31.

Table 5.40 — Image_Mapping_Method values
|
Value |
Description |
|---|---|
|
REPLACE |
For REPLACEimage mapping method, no calculations are needed; the colour and alpha (derived from <DRM Translucency>) of the <DRM Image> completely replace the original colour and alpha of the object (if any). |
|
DECAL |
For DECAL image mapping method, the <DRM Image> is essentially rendered on top of anything already there, like a decal (hence the name). For Type 1 and Type 2: the results are not specified. For Type 3: displayed colour = image colour and displayed alpha = original object alpha. For Type 4: displayed Colour = (1 - image alpha) × original object colour + (image alpha × image colour) and displayed alpha = original object alpha. |
|
MODULATE |
For MODULATE image mapping method, the <DRM Image>’s luminance (or colour) and alpha are linearly combined with those of the original object. For Type 1 Luminance: displayed colour = image luminance × original object colour and displayed alpha = original object alpha. For Type 1 Alpha: displayed colour = original object colour and displayed alpha = original object alpha × image alpha. For Type 2: displayed colour
= image luminance ´and
displayed alpha = image alpha ´
For Type 3: displayed colour
= image colour × original object colour and displayed alpha
= original object alpha. For Type 4: displayed colour
= image colour × original object colour and displayed alpha = image alpha × original object alpha. |
|
BLEND |
For BLEND image mapping method, the image blend colour of the object determines how the <DRM Image> is combined with the object’s primary colour. For Type 1 Luminance: displayed colour = (1 - image luminance) × original object colour + (image luminance × blend colour) and displayed alpha = original object alpha. For Type 1 Alpha: displayed colour = original object colour and displayed alpha = original object alpha × image alpha. For Type 2: Displayed Colour = (1 - image luminance) × original object colour + (image luminance × blend colour) and displayed alpha = original object alpha × image alpha. For Type 3: displayed colour = (1 - image colour) × original object colour + (blend colour × image colour) and displayed alpha = original object alpha. For Type 4: displayed colour = (1 - image colour) × original object colour + (blend colour × image colour) and displayed alpha = original object alpha × image alpha. |

This value is used to indicate that each texel in the <DRM Image> instance consists of an alpha value, representing the coverage of the texel. An alpha of 0 indicates that the texel is transparent, while an alpha of 1.0 indicates that the texel constitutes part of the important content of the <DRM Image> instance. A <DRM Image> instance with this signature may be called an alpha channel or an alpha map. For further details, see [FOLEY]. Note that an alpha map can be composited with:
FURTHER CONSTRAINTS:

|
LUMINANCE |
This value is used to indicate that the <DRM Image> instance specifies only luminance (also termed intensity) values that form a grey scale image, with no colour values. (The effect is that of a black and white television.) A LUMINANCE <DRM Image> instance can be composited with a compatible ALPHA image to produce a LUMINANCE_AND_ALPHA <DRM Image> instance. EXAMPLE An example of ompositing LUMINANCE <DRM Image> instances is the case of large areas of terrain <DRM Polygon> instances, where the same textures for dirt are repeated over and over. To avoid creating a “quilt” effect on the terrain, a LUMINANCE <DRM Image> instance can be composited with the terrain (using different offsets at different locations to make the effect appear random) to “dirty” the textures and give the terrain a more realistic appearance. FURTHER CONSTRAINTS: bits_of_luminance shall equal the size per texel (in bits); all other bits_of_xxx fields (and their corresponding minimum_value_of_xxx and maximum_value_of_xxx fields) shall be zero. |
|
COLOUR_COORDINATE_1 |
This value is used to indicate that each texel in the <DRM Image> instance consists of one colour component, namely the first for its colour model (G for RGB, M for CMY , or S for HSV ). The first colour component of the colour model shall be the only value in the texel. Note that a COLOUR_COORDINATE_1 <DRM Image> instance can be composited with compatible COLOUR_COORDINATE_2 and COLOUR_COORDINATE_3 <DRM Image> instances of the same dimensions to produce a 123_COLOUR <DRM Image> instance. (These can also be composited with a compatible alpha map to produce a 123COLOUR_ALPHA map.) FURTHER CONSTRAINTS:
EXAMPLES: An RGB texel shall have red as the texel value. A CMY texel shall have cyan as the texel value. An HSV texel shall have hue as the
texel value. |
|
COLOUR_COORDINATE_2 |
This value is used to indicate that each texel in the <DRM Image> instance consists of one colour component, namely the second for its colour model (G for RGB, M for CMY , or S for HSV). The second colour component of the colour model shall be the only value in the texel. Note that a COLOUR_COORDINATE_1 <DRM Image> instance can be composited with compatible COLOUR_COORDINATE_2 and COLOUR_COORDINATE_3 <DRM Image> instances of the same dimensions to produce a 123_COLOUR <DRM Image> instance. (These can also be composited with a compatible alpha map to produce a 123COLOUR_ALPHA map.) FURTHER CONSTRAINTS:
|
|
COLOUR_COORDINATE_3 |
This value is used to indicate that each texel in the <DRM Image> instance consists of one colour component, namely the third for its colour model (B for RGB, Y for CMY , or V for HSV ). The third colour component of the colour model shall be the only value in the texel. Note that a COLOUR_COORDINATE_1 <DRM Image> instance can be composited with compatible COLOUR_COORDINATE_2 and COLOUR_COORDINATE_3 <DRM Image> instances of the same dimensions to produce a 123_COLOUR <DRM Image> instance. (These can also be composited with a compatible alpha map to produce a 123COLOUR_ALPHA map.) FURTHER CONSTRAINTS:
EXAMPLES An RGB texel shall have blue as the texel value. A CMY texel shall have yellow as the texel value. An HSV texel shall have brightness
value as the texel value. |
|
BUMP_MAP_HEIGHT |
This value is used to indicate that the <DRM Image> instance represents a 2D height bump map (or just height map), specifying information used to modify the surface normals of a smooth surface. When used with a ray-tracing technique, bump mapping introduces variations in intensity across the surface, so that it simulates a rough, wrinkled, or dimpled surface (e.g., the surface of the ocean). A UV type of bump map can be derived from a height bump map by omputing the texel gradients in both the X and Y directions. Rather than manipulating the colour of a flat surface, bump mapping modifies the physical texture of the surface. For a description of bump mapping, see Section 7.8 “Bump Mapping” of [WATT].

EDCS_CLASSIFICATION_CODE |
This value is used to indicate that each texel in the <DRM Image> consists of one ECC value. FURTHER CONSTRAINTS:
|
|
LUMINANCE_AND_ALPHA |
This value is used to indicate that the <DRM Image> instance is (functionally) a composite of a luminance <DRM Image> instance and an alpha <DRM Image> instance (see ALPHA and LUMINANCE ). Each texel consists of an intensity value followed by an alpha value. No other ordering is possible with this signature. A LUMINANCE_AND_ALPHA <DRM Image> instance can be down-sampled to produce an ALPHA <DRM Image> instance and a LUMINANCE <DRM Image> instance. FURTHER CONSTRAINTS:
|
|
123COLOUR |
This value is used to indicate that each texel in the <DRM Image> instance consists of three colour components (RGB, CMY, or HSV). The first colour component of the colour model shall be the first value in the texel, the second colour component of the colour model shall be the second value in the texel, and the third colour component of the colour model shall be the third value in the texel. No other ordering is possible with this signature. Note that a 123COLOUR <DRM Image> instance can be down-sampled to produce a COLOUR_COORDINATE_1, COLOUR_COORDINATE_2, or COLOUR_COORDINATE_3 <DRM Image> instance. FURTHER CONSTRAINTS:
EXAMPLES An RGB texel shall have red as the first value in the texel, green next and finally blue. A CMY texel shall have cyan as the first value in the texel, magenta next, and finally yellow. An HSV texel shall have hue as the
first value in the texel, saturation next and finally brightness value. |
|
123COLOUR_ALPHA |
This value is used to indicate that each texel in the <DRM Image> instance consists of three colour components (RGB, CMY, or HSV) and an alpha value. The first colour component of the colour model shall be the first value in the texel, the second colour component of the colour model shall be the second value in the texel, the third colour component of the colour model shall be the third value in the texel, and the alpha value shall be the last value in the texel. No other ordering is possible with this signature. Note that a 123COLOUR_ALPHA <DRM Image> instance can be down-sampled to produce a COLOUR_COORDINATE_1, COLOUR_COORDINATE_2, COLOUR_COORDINATE_3, and/or ALPHA <DRM Image> instances. FURTHER CONSTRAINTS:
EXAMPLES An RGBA texel shall have red as the first value in the texel, green next, then blue, and finally alpha. A CMYA texel shall have cyan as the first value in the texel, magenta next, then yellow, and finally alpha. An HSVA texel shall have hue as the

These <DRM Property Table> instances describe the material. Normally, a <DRM Property Table Reference> instance is used to find the corresponding <DRM Property Table> instance’s data_table_type, to which the <DRM Axis> instance is referred, and which hash value measurement along that <DRM Axis> instance is being referenced. The bits_of_material_1 field is used in place of the <DRM Property Table Reference> instance’s index_on_axisfield. See the examples for the <DRM Image> class. FURTHER CONSTRAINTS:
|
|
TWO_MATERIALS |
This value is used to indicate that each texel in the <DRM Image> instance represents a linear combination of two materials in the <DRM Property Table> instances referenced by this <DRM Image> instance. That is, each texel consists of three values: two indexes into the <DRM Property Table> instances referenced by this <DRM Image> instance, and the percentage (an integer between 0% and 100%) of material_2. These <DRM Property Table> instances describe the materials. Normally, a <DRM Property Table Reference> instance is used to find the corresponding <DRM Property Table> instance’s data_table_type, to which the <DRM Axis> instance is referred, and which hash value measurement along that <DRM Axis> instance is being referenced. The bits_of_material_1 and bits_of_material_2 fields are used in place of the <DRM Property Table Reference> instances’ index_on_axis fields. See the examples for the <DRM Image> class. FURTHER CONSTRAINTS:

That is, each texel consists of four values: three indices into the <DRM Property Table> instances referenced by this <DRM Image> instance , and the percentages (integers between 0% and 100%) of material_2 and material_3. These <DRM Property Table> instances describe the materials. Normally, a <DRM Property Table Reference> instance is used to find the corresponding <DRM Property Table> instance’s data_table_type, to which a <DRM Axis> instance is referred, and which hash value measurement along that <DRM Axis> instance is being referenced. The bits_of_material_1, bits_of_material_2, and bits_of_material_3 fields are used in place of the <DRM Property Table Reference> instances’ index_on_axis fields. See the examples for the <DRM Image> class. FURTHER CONSTRAINTS:
|
|
IMAGE_INDEX |
This is used to indicate that the <DRM Image> instance consists of references to other <DRM Image> instances (i.e., each texel within the <DRM Image> instance is the index of another <DRM Image> instance). This mechanism allows an <DRM Image> instance to define high-resolution insets. Each texel is to be replaced by the entire <DRM Image> instance identified by the <DRM Image> instance whose index is specified by that texel. This allows data providers to create a large <DRM Image> instance formed by many smaller <DRM Image> instances. The index is an index into the <DRM Image Library> instance containing this <DRM Image> instance. FURTHER CONSTRAINTS:

Specifically, this enumerant exists to support the Generalized Digital Environmental Model, known as GDEM, which is a 4-dimensional steady-state digital model of ocean temperature and salinity, consisting of gridded sets of coefficients with very specific grid spacing values. This interpolation method uses polynomial deformation. One common use of this method is within tables representing sound speed profiles. |
|
BICUBIC_SPLINE |
Bicubic spline interpolation uses sixteen known data points to estimate the unknown value of c at a given a,b by fitting a bicubic surface to the sixteen closest data points and then evaluating for c. For more information, see [PRENTER]. |
|
KRIGING |
KRIGING is an interpolation method that predicts unknown values from data observed at known locations. This method uses variograms to express the spatial variation, and it minimizes the error of predicted values that are estimated by spatial distribution of the predicted values. Kriging interpolation estimates the unknown value using a weighted linear combination of the available sample. The weights for the linear combination are calculated by deriving the function of the data variogram and evaluating this function over the set of points in the data. For more information refer to [OLIVER]. |

YIQ_TO_RGB |
This lookup type is valid only when the <DRM Image Lookup> instance’s lookup table signature is RGB. This value converts the three colour components of a texel into three indices that are used to derive intermediate values that are recombined into a single RGB triplet:
Next, the I index is derived from the original texel RGB triplet by the equation: I_index = (0.49804 × red_component) - (0.22896 × green_component) - (0.26908 × blue_component) This index points to another RGB triplet in the lookup table. This triplet is used to derive the intermediate I value by the equation: I = (0.49804 × red_component) - (0.22896 × green_component) - (0.26908 × blue_component) The original RGB texel is used to generate the Q index by the equation: q_index = (0.20093 × red_component) - (0.49804 × green_component) + (0.29711 × blue_component) This index points to another RGB triplet in the lookup table. This triplet is used to derive the intermediate Q value by the equation: Q = (0.20093 × red_component) - (0.49804 × green_component) + (0.29711 × blue_component) Finally the intermediate Y, I, and Q values are combined to create the final displayed RGB triplet.

This data type specifies the status codes that can be returned by the API function GetLastFunctionStatus. The meanings for each status code are in Table 5.64. Additional information relating specific status codes with the functions that generate them may be found in Clause 7--Abstract API.
If a function should fail due to multiple reasons, INACTIONABLE_FAILURE shall be returned.
Table 5.64 — Status_Code values
|
Value |
Description |
|---|---|
|
SUCCESS |
This status code is returned when the function succeeded and no further information is provided. Other status codes do not necessarily indicate that the function failed. See particular functions for more information. |
|
NO_OBJECT |
This status code is returned by GetNextObject when there are no further objects to return that meet the specified criteria. |
|
DELETED_OBJECT |
This status code is returned when an object handle to an object that has been removed from a transmittal is passed in to an API function. |
|
DIFFERENT_TRANSMITTAL |
This status code is returned when valid parameters were provided but one or more objects were encountered that are in a different transmittal than the start object. This status is not an error condition when extracting objects, but is an error condition when attempting to remove objects from a transmittal. |
|
TRANSMITTAL_INACCESSIBLE |
This status code is returned by the open-transmittal functions if the resolved file location was not accessible by the API. This can occur if the file was opened for read-only or update access and the file does not exist. It can also occur if the file location specified a non-local file and the API had no transport mechanism available capable of accessing the remote file. |
|
UNRESOLVED_TRANSMITTAL |
This status code is returned when a reference to a transmittal is encountered that cannot be resolved. |
|
INVALID_ACCESS_MODE |
This status code is returned if the resolved file location of a transmittal was found, but the security permissions of the underlying operating system and/or file system prohibited access to the file in the mode specified. This can occur under any of the following conditions: a. the access mode specified was create or update and the file was marked read-only; b. no access was permitted for the account running the application; c. create or update mode was requested but the API implementation did not support write capability; d. a function requiring create or update mode was invoked for an object in a transmittal that was opened in read-only mode. |
|
UNSUPPORTED_FORMAT |
This status code is returned when a transmittal was requested in a format that is not supported by the implementation(s) of the SEDRIS API linked to the application. |
|
INVALID_TRANSMITTAL_NAME |
This status code is returned when a parameter representing a transmittal name did not specify a name that was valid according to the formal SEDRIS namespace as specified by the ResolveTransmittalName function. |
|
UNPUBLISHED_OBJECT |
This status code is returned when an object is encountered (while attempting to process an inter-transmittal reference) that is not published by its transmittal. |
|
UNRESOLVED_OBJECT |
This status code is returned when a DRM object handle is encountered that references a DRM object that is not available to the SEDRIS API, i.e., the DRM object is contained within a transmittal whose content cannot be accessed. NOTE This status is not necessarily an error condition. |
|
UNRESOLVED_START_OBJECT |
This status code is returned when an argument has been provided to an unresolved object. EXAMPLE A start object for an iterator. This status is an error condition, returned when the API requires access to the content of the unresolved object in order to perform the requested operation. |
|
INACTIONABLE_FAILURE |
This status code is returned to indicate a general, unknown, or other error for which there is no meaningful branch that the application code could make. This status code is returned when any invalid parameters are passed in to API functions. |
|
OUT_OF_MEMORY |
This status code is returned when the implementation is unable to allocate sufficient memory to satisfy the requirements of the function. |

This data type indicates the desired traversal order for a component iterator. The traversal order of the branches of a <DRM Aggregate Feature> or <DRM Aggregate Geometry> is determined either by the DRM or by the hierarchy_order_parameters for the iterator, but the general traversal scheme (i.e., the order to search for objects from the <DRM Transmittal Root> down to the maximum depth of the search) is specified using this data type.
All component iterators treat the start_object of the iterator as the “root” of a “composition tree”. The order of the tree traversal from that root is given by one of the enumerants described in Table 5.70.

Data types that are created from the basic fundamental data types are called structured fundamental data types. This mechanism provides support for arrays and lists of data types (both basic and structured) as well as data types that group several other data types into records.
Any data type can be combined in arrays. This data type provides support for instances where all of the individual data elements an ordered set are of like type. Arrays may be of one, two, or three dimensions. Examples of each are shown in Table 5.78:
|
One-dimensional arrays (lists): |
Data_Type_Name[l] |
|---|---|
|
Two-dimensional arrays: |
Data_Type_Name[l,w] |
|
Three-dimensional arrays: |
Data_Type_Name[l,w,d] |
The numbers l, w, and d represent the size of the corresponding length, width, and depth dimension. If the dimension is variable, an asterisk is used. A binding-specific method shall be provided for determining the size of the array.
EXAMPLE A data type for a variable length list of integers would be specified as:
Integer[*]
Similarly, a standard 4×4 matrix would be specified as:
Float[4,4]
The following standard array data types are specified:
Matrix_3x3 ::= Long_Float[3,3]
Matrix_4x4 ::= Long_Float[4,4]

Data types that encompass a variety of information are called record data types. A record data type consists of a sequence of fundamental data types that together form one record of data. Each entry of a record data type can be of any of the fundamental data types including other record data types.
Invariant record data types are specified as follows:
record_data_type_name ::= {
field1_name field1_data_type; optional comment
field2_name field2_data_type; optional comment
• • •
fieldn_name fieldn_data_type; optional comment
}
Record data types that specify a sized array indicate the size of the array by placing the name of the size parameter within the brackets for the array type as follows:
record_data_type_name ::= {
size_name size_data_type; optional comment
array_name array_data_type[size_name]; optional comment
}
Multiple arrays may be sized using the same size parameter. The maximum allowed size for the array is the maximum that can be specified by the data type of the size parameter. Record data types containing unsized or self-sized data may be specified by using the [*] notation specified in 5.3.2 Array data types.
In some cases, the data types used in the record data type depend on a parameter to the record data type. Such record data types are called variant record data types. The variant parameter (also called the discriminant) shall be a fundamental integer, enumerated, or selection item data type. The variant value fields shall consist of one valid value of the variant data and one entry shall exist for each of the possible values.
Variant record data types are specified as follows:
record_data_type_name ::= ( variant_name variant_data_type) {
variant_value1 : field1_name field1_data_type; optional comment
variant_value2 : field2_name field2_data_type; optional comment
• • •
variant_valuen : fieldn_name fieldn_data_type; optional comment

This data type specifies whether any components of the given <DRM Aggregate Geometry> and <DRM Aggregate Feature> instances should be traversed by a component iterator.
For instances of <DRM Aggregate Feature> and <DRM Aggregate Geometry> (referred to as "hierarchies" in these comments) for which inclusion rules can be specified:
If an instance of hierarchy object has a Hierarchy_Inclusion value of EXCLUDE_ALL, the rules within the Hierarchy_Select_Parameters for that type of hierarchy object are not evaluated. Objects of that hierarchy type and the components of those hierarchy objects are always excluded from the search space of the iterator.
If an instance of hierarchy object has a Hierarchy_Inclusion value of INCLUDE_ALL, the rules within the Hierarchy_Select_Parameters for that type of hierarchy object are not evaluated. Objects of that hierarchy type and the components of those hierarchy objects are always included in the search space of the iterator.
If an instance of hierarchy object has a Hierarchy_Inclusion value of EVALUATE_RULES, the rules within the Hierarchy_Select_Parameters for that type of hierarchy object are evaluated for each hierarchy component attached to the hierarchy object. Only hierarchy components whose link attached data pass the rules are included in the search space of the iterator.
For types of hierarchies for which inclusion rules cannot be specified:
If an instance of hierarchy object has a value of FALSE, all objects of that hierarchy class and the components of those hierarchy objects are always excluded from the search space of the iterator.
If an instance of hierarchy object has a value of TRUE, all objects of that hierarchy type and the components of those hierarchy objects are always included in the search space of the iterator.

This data type determines the traversal order of the branches a <DRM Aggregate Feature> object or <DRM Aggregate Geometry> object encountered by a component iterator. If a <DRM Aggregate Feature> object or a <DRM Aggregate Geometry> object contains unordered branches, the traversal order of these branches is random by default. By using traversal order parameters, the order in which the branches will be traversed can be controlled.
If a given type of aggregate object is not given any traversal order controls, the components of that type of aggregate object will be traversed in a random order, unless the aggregate object itself is specified with an ordering of branches in the data model.
GENERAL HIERARCHY MASK:
A set of Boolean, one for each “type” of aggregate hierarchy instance, to indicate whether any of the branches from that class of instance should be traversed, and if so, whether all of the branches will be traversed, or whether the selection parameters for that “type” will be evaluated. General_Hierarchy_Select provides more details.
ANIMATION RELATED GEOMETRY:
No order parameters are provided for an <DRM Animation Related Geometry> because the traversal order of a <DRM Aggregate Feature> object or <DRM Aggregate Geometry> is already specified by the data model. The frames of an animation are ordered and that ordering is the order in which the frames shall be traversed.
LEVEL OF DETAIL RELATED GEOMETRY and LEVEL OF DETAIL RELATED FEATURES:
Ascending Order:
Distance: Branches with lower minimum ranges shall be first.
Index: Branches with lower indices shall be first.
Map Scale: Branches with lower minimum scales shall be first.

PERIMETER RELATED GEOMETRY:
No parameters are specified for dealing with a <DRM Perimeter Related Geometry> object. If the order of traversal is important, the use of multiple iterators, each with a different Spatial Search Boundary, should be specified.
CONTINUOUS LEVEL OF DETAIL GEOMETRY:
No ordering is allowable.
UNION:
All of the components of a union object are already ordered by the data model, so no ordering parameters are required.

This data type determines which “branches” or “switches” to traverse from an <DRM Aggregate Feature> object or <DRM Aggregate Feature> object encountered by a component iterator. These parameters determine which branch will be followed based on the field values of the link object attached to that branch.
If a certain type of aggregate object is not given any selection controls, all of the components of that type of aggregate object will be traversed whenever an aggregate object of that type is encountered.
GENERAL HIERARCHY MASK:
A set of Boolean, one for each “type” of aggregate hierarchy instance, to indicate whether any of the branches from that class of instance should be traversed, and if so, whether all of the branches will be traversed, or whether the selection parameters for that “type” will be evaluated. General_Hierarchy_Select provides more details.
PERIMETER RELATED GEOMETRY:
No parameters are specified for dealing with a <DRM Perimeter Related Geometry> object. By default, all components of a <DRM Perimeter Related Geometry> object will be traversed (unless Perimeter Related is “masked out” by an FALSE value in the general_hierarchy_mask, in which case, none of the components of a <DRM Perimeter Related Geometry> will be searched). In order to selectively limit the components traversed from a <DRM Perimeter Related Geometry> object, a Spatial_Search_Boundary may be specified when initializing the Component Iterator.
UNION:
All components of a Union object are always traversed (unless that type of union is masked out by a FALSE value in the general_hierarchy_mask parameter, in which case none of the components for that type of union are traversed).

The font family is the name given to a set of fonts by a font designer. The font family can identify generic (e.g., SANS-SERIF and SERIF) or proprietary names (e.g., Clarendon or Lucida). The font family may have subfamilies. If so, the subfamily is identified as part of the name (e.g., Lucida Blackletter). The font family is specified by a String field. The maximum length of a font family name is 32 characters.
The font style specifies the appearance variation allowed within the font family.
The font size specifies how big the text is to be presented. Size is specified in points. The implementation shall provide a rational means of mapping points to the size of text in a presentation. Default size is 11 points. Since this element is specified as a float, the size specified may not be mappable to the sizes available for a particular font family. In that case, the size available that is nearest to the requested size shall be used
The underline style specifies how text is underlined. The default style is NONE. If a style is specified that is not recognized by an implementation, SINGLE shall be used. The width of the line used to implement the underlining shall be appropriate to the font size and font style specified.

Private data types are those data types whose exact structure is hidden. Such data types are manipulated solely using functions. This allows an implementation to store the data that shall be maintained for the data type in whatever form is convenient for the implementation.
This data type specifies information that is used to cycle repeatedly over some aspect of a SEDRIS transmittal.
An iterator allows a user to step through a collection of objects related to the iterator’s start object, where the elements of the collection satisfy the conditions used to initialize the iterator. (For instance, an iterator may be initialized with a search filter.)
The relationship of the start object to the objects in the collection depends on which function was used to initialize the iterator.
Iterators in SEDRIS have the following characteristics:
More details are available in the various iterator initialization functions (see 7.3.62 InitializeAggregateIterator, 7.3.63 InitializeAssociateIterator, and 7.3.64 InitializeComponentIterator), as well as in 7.3.35 GetNextObject, 7.3.47 GetRemainingObjectsList, and 7.3.13 FreeIterator.
More information on the iterator behavioral pattern and external iterators is available in [GAMMA].
This data type stores a means to access a DRM class instance. An instance of this type is called a DRM class handle.

NOTE To be available for inter-transmittal referencing (ITR), a SEDRIS object shall be published.
This data type stores a means to access a packed hierarchy object.
This data type stores information that is used by the API during spatial searches.
This data type stores information that is used as a search filter during searches of a transmittal.
A search filter is created by calling CreateSearchFilter, which provides a set of rules that are used by iterators to filter objects so that only objects that pass the rules will be returned to the user.
Search filters have the following characteristics:
This data type supports the specification of arbitrary data to be used by the implementation during searching.
This data type is used to maintain the implementation dependent information necessary to access a transmittal.
This part of ISO/IEC 18023 provides for the specification of arbitrary “call-back” functions that are provided by the application but invoked by the implementation. Such functions shall have the function signature specified for each function data type.
This data type is a call-back used during searching. Whenever the rule_type value for a Search_Rule data type instance holds the value of PREDICATE, a function with the following signature shall be provided:
Return value: Boolean
Parameters: Object
Object
Test_Data
