Nice! Out of curiosity can you share what your use case is? I would be
really interested to hear more as I am interested in domain modeling and
deduplication is part of this.

Absolutely yes. I just need to know more about the structure of the
Signature implementation. Did you extend Signature [0]? If so then it will
be packaged along with the Nutch .job jar and can be invoked via the
following property [1] db.signature.class

[0]

You may be good invoking this as part of the 'core' codebase instead of as
a plugin implementation. Please let us know based upon the above.
Thanks
