The exploitation of the growing amount of information produced by systems is often associated with the paradigm of Big Data. Next to this approach it remains the interest in integrating information of different origin within a shared framework, conceptually formalized by an ontology.

The IEC Common Information Model (CIM) is a natural candidate to take on the role of reference ontology in the electrical context being able to describe different types of electrical domain information (eg. topologies of electrical networks, market information, metering, etc.. ) in an integrated way.

The activities described here have adopted the CIM standard as a reference for the integration of information gathered from Power Quality (PQ) monitoring of medium voltage distribution networks, in order to demonstrate the possible synergies with the types of information already provided in that reference model, namely those associated with topologies network, and cartographic information. The result of this integration could be in perspective leveraged in the frame of the Big Data and the Open Linked Data paradigm.
