What is the CRMdig?

CRM Digital is an ontology and RDF Schema to encode metadata about the steps and methods of production ("provenance") of digitization products and synthetic digital representations such as 2D, 3D or even animated Models created by various technologies. Its distinct features compared to competitive models is the complete inclusion of the initial physical measurement processes and their parameters. It has been developed as compatible extension of CIDOC CRM, which allows for querying the most relevant facts and returning complete descriptions encoded in this model by generic ISO21127 terms without need to refer to its specific properties. In contrast, competitive models cannot be queried by a more general standard and are restricted to the computational provenance only. Data encoded in the major competitive models can be transformed without loss of meaning into a CRM-Digital-form.

CRMdig is a proposal for approval by CIDOC CRM SIG

What is the idea?

The use of CIDOC CRM for provenance modeling  has been conceived in the framework of the European IP CASPAR for different disciplines (digitization, born digital objects, performing arts, satellite data) by interpreting OAIS guidelines and was fully developed and tested on relevant data sets in the framework of the European IP 3D-COFORM. During the latter, also the mandatory practical user guidelines for the identification description of provenance-related entities, such as physical objects, equipment, software, people, time where developed and a repository infrastructure capable to effectively store, query and access such metadata and the related data items has been created. As such, 3D-COFORM has a real impact in drawing together the workflow from initial data capture to communication of results.
