There is no formal way to sign it, but you can get a trusted copy of the
original if the author provides a faithful representation in it in RDF
(which is what GRDDL and other similar mechanisms - RDFa, etc. - are all
about).  This does carry some authority about how well the statements
represent the information in the original artifact.  In addition, the
concrete syntax can be signed digitally (same as any other file), authorship
can be asserted in the content (Clinician A created the set of RDF triples
B) in addition to other provenance such as when it was created which
structured data source it was transcribed from.
