This International Standard specifies EDCS attributes that describe the state of environmental objects. Within the EDCS Attribute Dictionary, each EA has a unique concept definition and is denoted by both a unique EAL and a unique EAC. Each EA has an EDCS attribute value type and has an associated EQ if the EDCS attribute value type is REAL.
The EDCS Attribute Dictionary is presented in 27 tables. One table contains all deprecated EAs. Each of the other 26 tables, one table for each letter of the alphabet, consists of EAs with the same first character of their EALs. Within each table, the EAs are ordered alphabetically by the EAL.
This International Standard does not associate any EA with any EC(s).
This International Standard specifies EDCS attribute value characteristics that describe information concerning the values of EAs. Within the EDCS Attribute Value Characteristic Dictionary, each EV has a unique concept definition and is denoted by both a unique EVL and a unique EVC.
The EDCS Attribute Value Characteristic Dictionary is presented in two tables with the EVs in a natural order in each table.
For each EA whose EDCS attribute value type is ENUMERATION, this International Standard specifies the members of the set of values of that EA as EDCS attribute enumerants. Each EE has a concept definition and is denoted by both an EEL and an EEC. The concept definition, EEL, and EEC are unique only within the context of that EA.
The EDCS Attribute Enumerant Dictionary is presented in 27 tables. One table contains all deprecated EEs. Each of the other 26 tables, one table for each letter of the alphabet, consists of EAs with the same first character of their EALs, however, only EAs whose EDCS attribute value type is ENUMERATION are included. The EAs are ordered alphabetically by their EALs in each table, with each EA followed by its associated EEs. The EEs for each EA are presented in a natural order.
The EAs specified in this International Standard are presented in Tables 6.5 through 6.30, in Table A.4, and in Tables C.2 through C.27. The specification of each field of an EDCS Attribute Dictionary entry is presented in Table 6.3. The first five fields are presented in Tables 6.5 through 6.30 and Table A.4. The label field and the last three fields are presented together in Tables C.2 through C.27. The EALs in Tables 6.5 through 6.30 and Table A.4 are hyper-linked to the corresponding entries in Tables C.2 through C.27.

The EEs specified in this International Standard are presented in Tables 6.36 through 6.61, Table A.5, and in Tables D.2 through D.27. The specification of each field of an EDCS Attribute Enumerant Dictionary entry is presented in Table 6.34. In order to clarify the presentation of multiple EEs for each EA, the applicable EA is presented once prior to the presentation of its set of EEs. The EA is then not repeated for each of its EEs and instead the presentation of the EAL field is grey. The enumerant label and code fields in the horizontal row that contains each EAL are presented in grey because these fields do not apply to the EA. The first four fields are presented in Tables 6.36 through 6.61 and Table A.5. The EAL and EEL fields and the last three fields are presented together in Tables D.2 through D.27.

An EE concept may be defined to be the same as an EC concept. In this case:
Within each table, EEs are first ordered alphabetically by EAL and then, for each EA, the EEs are presented in a natural order. The alphabetical organization by EAL is reflected in the structure of Table 6.35.
