Knowledge Source Knowledge Source protocol schemas
Knowledge Source — declarative metadata describing what to index and
which adapter to use.
A KnowledgeSource is the metadata-level equivalent of an
IDataEngine driver binding: it pairs a logical source description
(object/file/http) with the id of an IKnowledgeAdapter plugin
that will actually do the work. The adapter resolves the id at
runtime via IKnowledgeService.registerAdapter.
See content/docs/protocol/knowledge.mdx for the full design.
