This section documents changes to the SciGraph core ontology between the 2017Q4 and 2017Q1 releases.

  • Latest release (2017Q4)

    The Springer Nature SciGraph Core Ontology (v1.2.0) is the main model encoding the semantics of the Springer Nature SciGraph 2017Q4 data release. It is implemented as an OWL 2 ontology, with a DL expressivity ALHI(D), and consists of 47 classes and 253 properties. The ontology lives within its own SciGraph namespace:

    prefix: sg
    namespace: http://scigraph.springernature.com/ontologies/core/

  • Previous release (2017Q1)

    The Springer Nature SciGraph Core Ontology (v1.0.0) is the main model encoding the semantics of the Springer Nature SciGraph 2017Q1 data release. It is implemented as an OWL 2 ontology, with a DL expressivity ALHIF(D), and consists of 45 classes and 206 properties. The ontology lives within its own SciGraph namespace:

    prefix: sg (deprecated)
    namespace: http://www.springernature.com/scigraph/ontologies/core/

See the Namespaces page for all namespaces used in SciGraph.

Change Description
Base URL The SciGraph namespace itself now uses a dedicated subdomain (scigraph), rather than the earlier path name /scigraph
Expressivity The expressivity of the Core Ontology was simplified from ALHIF(D) to ALHI(D), i.e. functional properties were removed.
