Supporting the ontology data model are a number of processing technologies to manage your ontologies.
This feature allows you to create schemas for new ontologies and to create concepts, link concepts and carry out any other ontology building tasks.
This feature allows you to navigate and interrogate the ontology. On top of this you can build visualisations of your knowledge and infer information about your domain.
Often multiple ontologies are modelled with the intention of creating larger ontologies by merging smaller ones. For example within an organisation there may be ontologies for different departments which are merged to form a company-wide ontology.
Sometimes an ontology needs to be transformed into another ontology. In this case a set of filter rules can be defined to describe how the transformation should take place. This allows you to maintain a single ontology for potentially multiple purposes. For example a product ontology may have regional variations, so we can build a single ontology and define rules for each region to build the regional ontology.
There may be cases where multiple ontologies are maintained separately but certain aspects need to be in alignment with each other. This is particularly useful in mapping external ontologies to your own variant. For example you may aggregate information from a number of sources and need some way to map the terminology used by those individual sources to that used by you internally.
Refer to the detailed specification and guide for the ontology definition language.
