Information technology - Environmental Data Coding Specification (EDCS)

Abstract

ISO/IEC 18025:2014 provides mechanisms to specify unambiguously objects used to model environmental concepts. To accomplish this, a collection of nine EDCS dictionaries of environmental concepts are specified:

1. classifications: specify the type of environmental objects;

2. attributes: specify the state of environmental objects;

3. attribute value characteristics: specify information concerning the values of attributes;

4. attribute enumerants: specify the allowable values for the state of an enumerated attribute;

5. units: specify quantitative measures of the state of some environmental objects;

6. unit scales: allow a wide range of numerical values to be stated;

7. unit equivalence classes: specify sets of units that are mutually comparable;

8. organizational schemas: useful for locating classifications and attributes sharing a common context; and

9. groups: into which concepts sharing a common context are collected.A functional interface is also specified.
