The OntoRail knowledge engine supports multiple means to visualize, navigate and search ontologies that have been imported into its RDF knowledge graph.

Global Search

The OntoRail knowledge engine supports the import of multiple ontologies into a RDF knowledge graph and each of those ontologies may be imported in multiple versions. To support searching through a potentially large set of concepts, OntoRail implements a Global Search functionality which allows to search across a subset or all ontologies that have been imported. It is acessible from the main panel.

Once invoked, the Global Search widget allows to:

  • select (filter) the ontology or ontologies that will be the object of the search
  • provide a search term

The results are displayed below, ordered by ontology. The search results are hyperlinked so that they may be consulted in the Tree Browser.
