After the construction of the OntoMP, the next stage was to describe it in a standard ontology used for museums, CIDOC-CRM. The ontology was built up having in mind the need to keep it fully compatible with the original, avoiding to add or modify any class.

Based on the first drawn of OntoMP as stated in the process of reverse engineering, we converted OntoMP to a CIDOC-CRM compatible form ontology with the objective of adopt a standard format used in the museums area. In this way we preserve the interoperability of our repository for further exploration and knowledge extraction. The next image shows the CIDOC-CRM version of Onto MP structure.

The image above portrays the instantiation of CIDOC-CRM with a concrete life story.

According to the abstract layer of the CIDOC-CRM ontology of the figure above: a life story (E31 Document) is about (P129) a person (E21 Person) and contains photos (E38 Image) concerning that person.

Looking to the concrete layer of that ontology, we read that: Maria Cacheira (E21 Person), participated in the (E5 Event) of her (E67 Birth). This event occurred at (E52 Time Span)—that is identified by (P78) 1946-10-08, an (E50 Date)—and at a (E53 Place)—that is identified by (P87) Afurada, an (E44 Place Appellation).

To sum up, notice that in the figure above is shown a description of a specific life story mapping the life story concepts and relations into the standard CIDOC-CRM elements. In that way (following that standard representation) it will be possible to query systematically the knowledge repository to explore it.
