The CX Ontology is a versioned folder of domain ontology files (and tools to process them)
Each domain ontology file is written in a format named Turtle (TTL). Following the Resource Description Framework (RDF), these files defines
- semantic concepts (classes of entities/nodes, where a node can have multiple classes)
- properties (attributes of entities using primitive node types) and
- relations/predicates (which are links between nodes where the source node is called subject and the target node is called the object)
All definitions in a file should belong to the same namespace (which is the technical key of the domain) and should be using a common nickname (prefix) that is also the name of the file.
Domain ontologies can refer to concepts of other domains/prefixes. Relations are usually attributed to the concept/domain which cannot exist without the relation.
