             Summary: We need a model type for handling chains with one-level versioned directories
                 Key: CONNECTORS-999
                 URL: https://issues.apache.org/jira/browse/CONNECTORS-999
             Project: ManifoldCF
          Issue Type: Improvement
          Components: Framework crawler agent
    Affects Versions: ManifoldCF 1.6.1
            Reporter: Karl Wright
            Assignee: Karl Wright
             Fix For: ManifoldCF 1.7


The framework currently handles CHAINED models by expecting that reference extraction take
place on all documents with references, regardless of whether those documents have changed.
 But a far more common kind of situation is when a document's references are accurately captured
by its version information.  It would be great to perform incremental crawls in this case
without doing any reference reference extraction.

Such a scan would require requeuing of all existing documents, which would make minimal scans
have to process more documents.  But this could be a positive tradeoff if versioning a document
was cheap compared to processing it.

Maybe a new class of models, e.g. VERSIONED_CHAINED, might make sense to consider adding.
