Queries to CIM RDF

The package invokes SPARQL queries against a CIM RDF (ttl, xml, or json) file to load Python dictionaries. The dictionary keys and field names use CIM attribute names, which are fully qualified with the CIM class name only as needed to resolve ambiguities. The tables in this section document the keys and field names for each Python dictionary, along with the corresponding CIM fully qualified attribute names. Each dictionary is briefly described, with links to the main CIM classes that the dictionary is based on.

The CIM Attribute begins with a CIM namespace as follows:

  • c: denotes the prefix for base CIM

  • e: denotes the prefix for an Emtiop extension

Some queries may return multiple rows for each dictionary key. These queries are indicated with an asterisk, e.g., EMTIEEECigreDLLParameters*. Those dictionaries must be iterated using the Python .items() construct.
