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.
Hierarchical view (Tree Browser)
The Tree Browser provides a searchable hierarchical view over a source ontology and its concepts. It can be accessed as a consequence of using the Global Search or when invoked from an ontology subpanel on the main page of OntoRail.
It provides a rich, hyperlinked & unified browsing of source models with quick access to:
- the official documentation page of the model
- a tree view of the model packaging structure
- the entity high-level description (where retrievable)
- the entity properties
- the entity documentation page (where retrievable)
as well as search functionalities allowing to quickly navigate models that can be quite comprehensive.
Graph view
The graph view of the OntoRail knowledge engine is provided by the Visual Graph functionalities of the GraphDB Semantic Graph Database.
It provides a graph view of the relations between the concepts of an ontology (here, the RailSystemModel)...
... but also between concepts of multiple ontologies (here, the concept of VehicleStop).
For details on how to explore the Graph view, please refer to the GraphDB documentation.
