When the DAF is used to access power system model data, a schema derived from the EPRI CIM will be employed. This schema
is undergoing standardization in the IEC under Technical Committee TC57. From time to time, the IEC may standardize newer
versions of this schema, which the OMG may designate as the DAF standard. When this happens a new OMG document number will
be issued.
There are two URIs designating the EPRI CIM schema:
1. The EPRI CIM document URI gives the location of the schema document on the public internet. This URI points to the OMG document dtc/2000-11-10 [8] and is subject to change if the OMG rearranges its web site. The document URI plays no part in the operation of the interface. Neither clients nor data providers need to recognize the document URI.
2. The EPRI CIM namespace URI identifies a schema, including its version. This URI is used purely as a name and it does not necessarily identify any document on the public internet. It is used in the interface to uniquely and universally identify CIM classes, properties, and enumerated values. Implementations complying with the EPRI CIM conformance point must recognize this URI in the ResourceIDService::get_resource_ids() operation.
The EPRI CIM namespace URI will normally take the following form:
http://iec.ch/TC57/2000/CIM-schema-<version>
The current version of this schema has the following namespace URI:
