Introduction to Custom Ontologies and Custom Schemes

A custom ontology is the conceptual representation of the concepts, their attributes and the relations between them in Graph Modeling. It also defines the underlying data model for a Graph Modeling project. This is where to organise your data, to improve the search and to integrate this data. To apply this data model to a Graph Modeling thesaurus, you need to create a custom scheme based on your custom ontology or a predefined ontology and synchronize it.

A core ontology has a set of classes, relations and attributes for a specific domain. You can use them on their own or as part of a new custom ontology.

A custom scheme is a container with elements of custom and/or a core ontologies. A custom scheme is where these ontology elements can be brought together and applied to your Graph Modeling data. The definitions of the elements used by the custom scheme cannot be edited within the custom scheme itself, but by editing the custom ontology.
