Graph Triples ETL

Hi,

Don't know if this list is adequate for this kind of posting. I'm currently
doing research about the possibilities of building some sort of framework
or tool which should enable knowledge extraction of information coming from
data in the form of raw graphs of triples:

One goal would be to automatize ETL tasks inferring the structures that
could arise (knowledge) once the available information is aggregated from
the source data.

Best regards,
Sebastián.
