The Content Repository is the AFS v7 service (content) in charge of storing and giving access to the document units used to build the index base. It makes it possible to associate accurately the indexed documents and the search results.
The Content Repository also stores each documents layers created by the AFS-PaF process (examples: DocBook conversion, project specific layer such as cross reference indexes, RDF triples, etc.) Because the indexing documents are giving additional data, replies to the search engine client are more specific and relevant.
Through the Content Repository, both AFS standards layers (CONTENTS, etc.) and project-specific layers can be retrieved.
