OpenCitations

Model

The metadata model used for the data stored in the OCC is briefly summarised in Figure 1 and is described in:

Silvio Peroni, David Shotton (2016). Metadata for the OpenCitations Corpus. figshare. https://dx.doi.org/10.6084/m9.figshare.3443876

The model is explicitly aligned with the SPAR Ontologies and other well-known vocabularies, including:

For convenience, all the terms from the aforementioned ontologies are collected within a new ontology called OpenCitations Ontology (OCO). This is not yet another bibliographic ontology, but rather just a place where existing complementary ontological entities from several other ontologies are grouped together for the purpose of providing descriptive metadata for the OCC.
