Ontology Gateway Services

Previous

Object Set Service

Next
Built with

Ontology Gateway is Method’s data layer. It owns the platform’s ontology — the typed knowledge graph that links environments, objects, properties, and the issues raised against them.

All services in this section share a base host (typically https://<stack>.method.delivery/ontology-gateway/api), with each service rooted at its own sub-path.

Services in this section

  • Object Set Service — find an object set and list its member IDs.
  • Object Service — load individual ontology objects, search them, and read their history at a given timestamp or version.

Common types

  • ObjectSetId — a Method Resource Identifier (RID) of the form ri.ontology..objectset.<uuid>.
  • ObjectId — an identifier for a single ontology object, unique within an environment.
  • EnvironmentId — identifier for a customer-defined environment that scopes objects.
  • PropertyId — identifier for a typed property defined on an object type.
  • UserId — identifier for a user.

These are referenced by name throughout the per-service pages.
