Glossary

API key — A secret token (oc_live_…) that authenticates an AI tool against a single world, with a fixed read-only or read-write permission. One of two ways to connect a tool; the other is signing in. See Generate an API key.

Collaborator — Someone you’ve invited into a world. Each collaborator has a role. See Collaborators and permissions.

Connector — Orbismo’s single MCP URL (/api/v1/mcp) that, after you sign in, reaches every world you grant it and lets the agent switch between them. See The connector.

Connected app — An AI tool you’ve authorized via the connector. You manage which worlds each one can reach, and revoke them, from the portal’s Connected apps page.

Default schema — The general-purpose set of entity types and relationship types every world is created with. There’s no template to choose; you adapt and extend the one schema. See Data model.

Entity — A thing in your world — a person, place, event, group. Entities are the nodes of your world’s graph. See Entities and relationships.

Entity type — The category an entity belongs to (Person, Place, …). Every world starts with a default set, which you can extend. See Data model.

Lore — Long-form prose attached to an entity. Indexed for semantic search. See Lore.

MCP (Model Context Protocol) — The open protocol AI tools use to connect to your world. See How AI integration works.

Media — Images and files that can be attached to entities; a world’s media storage allowance is set by its plan.

Plan — The paid subscription a world is on (Basic, Standard, Team 5/10/20), setting its limits. Plans attach to worlds, not accounts. See How pricing works.

Portal — The Orbismo web app, where you browse the canon and manage worlds, settings, and collaborators.

Relationship — A directed, typed connection between two entities (“is a member of”, “lives at”). The edges of your world’s graph. See Entities and relationships.

Role — A collaborator’s permission level on a world: Owner (full control, including billing), Editor (read and author content), or Viewer (read-only). See Collaborators and permissions.

Semantic search — Search by meaning rather than exact words, powered by indexing your lore. Surfaced through a connected AI tool. See Search and discovery.

Tag — A label from a shared, controlled vocabulary applied across entities to keep terms consistent.

World — A self-contained universe with its own entities, lore, collaborators, and subscription. You can own several. See Worlds.

Semantic predicate — A meaning-based, conceptual link between entities (inspired_by, similar_to, derived_from, …), distinct from the structural relationship verbs. See Data model.

World prompt — Standing instructions an owner sets for a world, sent to AI agents so they follow its voice and conventions. Edited under World Settings. See World prompt and examples.
