>
> To generate a document signature (MD5 digest) of the binary content requires
> that documents are parsed during the parse or fetch step. The signature is
> required for deduplication and detection of unmodified content and should be
> always available, also in a workflow which does not require that documents
> are parsed, e.g., because HTML content is exported to WARC files.
