I'm a semantic web folk (I'm on the PROV Data Model), and I'm willing to
advise as needed. PROV is very generalized, but workflow provenance was one
of the primary use cases for its design (it descends from OPM, which was
almost entirely workflow provenance-oriented).

Workflow tools probably should be prov:Plan, a subclass of prov:Entity.
PROV can cover attribution of things, agents (people and orgs) acting on
behalf of other agents, and virtual and physical locations
(prov:atLocation). Tool provenance is a little smaller-scoped than workflow
invocation provenance, but obviously we want the two to mesh neatly.

Below I'm going to use Turtle to write out an example, but the tool XML can
obviously embed RDF-XML instead.

We would need to supply a little bit of our own vocabulary:

galaxy:Tool rdfs:subClassOf prov:Plan.

Citing a book in a tool might look like this:

:mytool a galaxy:Tool;
   prov:wasDerivedFrom <http://dx.doi.org/10.1119/1.15378> ; # For DOI-able
references. [1]
   dc:creator <http://tw.rpi.edu/instances/JamesMcCusker>.

[1] dx.doi.org will return RDF for the document if you ask for it. We can
use their vocabulary within our own RDF if there is no DOI for it.
