The repository contains two directories including respectively 100 XML files, describing photographs and artworks depicted in photographs, and 100 RDF/XML files, i.e., the output of the convesion of former XML files according to CIDOC-CRM and other few ontologies - see Ontologies section.
N.B. Data will be slightly modified soon, so as to be compliant with aac mapping rules.
Data here published: CC-O. Complete RDF dataset: CC-BY 4.0. Documentation: CC-BY 4.0.
The RDF dataset published by the Zeri Foundation is available at the Zeri & LODE project web page. Here you'll find several data access points - like a SPARQL endpoint wherein directly query the triplestore, or a RDF Browser to browse links in a user-friendly way. A dump can be downloaded from AMSActa institutional repository.
Data are mainly converted to RDF/XML according to CIDOC-CRM. Few relations and classes belong to other ontologies, since CIDOC-CRM doesn't provide a comprehensive description of topics that are relevant to understand Zeri's data. Indeed, the aim is to integrate CIDOC-CRM.
All terms belonging to ontologies but CIDOC-CRM, have been imported in two specular ones for the sake of clarity, namely:
Imported ontologies and used as modular, task ontologies, i.e., they are used to cover specific topics, namely:
Zeri catalog entries conform two national content standards, called respectively Scheda F - photography - and Scheda OA - artwork.
Two mapping documents have been realized to explain the alignments from content standard fields to CIDOC-CRM and aforementioned ontologies, i.e., FtoRDF and OAtoRDF.
An graphical overview of the two mappings can be found in "mapping" directory.
