oslc.where Parameter

The 'oslc.where' Query parameter specifies the conditions that the resources must satisfy; it is similar to the WHERE clause of an SQL statement. This parameter must be appended to the base URI of the Query Capability in Enterprise Architect as:

     <protocol>://<server>/<model_name>/oslc/am/qc/?oslc.where=<conditions>

The syntax for the 'oslc.where' Query parameter (defined in BNF grammar and as specified in the OSLC Query Syntax Specification) is:
