Definition |
An instance of this class provides an EDCS_Classification_Code (ECC) indicating what the object to which the <DRM Classification Data> is being applied represents. If the ECC requires elaboration by EACs, the <DRM Classification Data> may have elaborating <DRM Property Value> components. <DRM Classification Data> is used in three different contexts: a. A <DRM Classification Data> instance can be a component of a <DRM EDCS Use Summary Item>; see that class for an explanation of its usage. b. If X is an instance of a DRM class other than <DRM EDCS Use Summary Item>, and X has a <DRM Classification Data> instance as a component, the <DRM Classification Data> specifies what X represents. c. If X and Y are SEDRIS objects such that X has Y as a component with a <DRM Classification Data> instance as a link object on the relationship, the <DRM Classification Data> specifies what Y represents. For this case, see <DRM Classification Related Features> and <DRM Classification Related Geometry> for a more detailed discussion. |

Example(s) |
· An EDCS Classification code such as ECC_DRIVE_IN_THEATER or ECC_ROAD. · Consider a <DRM Point Feature> that has a <DRM Classification Data> object with a value of ECC_BUILDING as a component. The <DRM Point Feature> is therefore identified as a building. |
