The main outcome from the metadata analysis is a quite evident difference between libraries and museum metadata standard application. The online catalogue of the libraries holding the items provided metadata following ISBD guidelines and MARC format. On the other hand, none of the museum institutions holding the items properly followed the CCO content standard and the related structure standard CDWA but rather provided metadata based on custom standards - even though evidently inspired by the CDWA Core Categories.

The theoretical model was built starting from the description of the single items provided by the metadating of the CH institutions. All the features of the items provided in the property:value format by the institutions have been modeled in natural language triple statements. Other relevant information have been added to provide a clearer model of the relation between the different types of item in our collection and their connection with Vivienne Westwood.

Starting from the predicates and entities described in natural language in the theoretical model, we began mapping the triple statements into RDF syntax. For most of the predicates and classes of the entities the privileged sources were schema.org and DCMI, while for people we referred to FOAF. As for some domain specific predicates and classes, CIDOC-CRM and the LIDO model have been used. Literals on the other hand were made explicit by specifying their datatype using the XML Schema Definition (XSD) language.

The ontology was modeled following FRBR for the concept of Item: all the objects are described at item level so we specified that each item is an instance of the class FRBR Item.

We made Vivienne Westwood and the whole collection of items a part of our ontology and we defined our own classes for the types top, corset and wallpaper because no similar type was available online; the same was done for the slipcase format by adding it to the ontology. For the items of which we defined a type inside of our ontology we had to specify that they were physical human made things as this was not implicit in their custom made type; this, on the other hand, is implicit for the rest of the items which all have types which are subclasses of schema/CreativeWork, which implies a Thing (either physical or not).
