TCRS Requirements
Common types of TCRS requirements :
Specify which EDCS classification codes must be present.
Define which EDCS attribution is needed for given classification codes.
Define what SRF(s) the location data is expected to be in.
Specify what organization or structure of the transmittal hierarchy is used. (ex. Spatial Index Related Geometry followed by Classification Related Geometry.)
Define which DRM classes are used to represent the ‘things’ in a transmittal (ex. Roads are represented as a Linear Feature with a Classification Data of ECC_ROAD.)
Specify that a certain number of ‘things’ must exist in a transmittal. (eg. Can impose a maximum limit on the number of ‘things’.)
Specify that given DRM classes may not exist in a transmittal.
