Sounds very interesting initiative. Based on my understanding, I think
it should be possible to write a tool that read any OWL document and
generate a VOAF document. May be Swoogle could be a good starting
point, but not sure how the API can provide the list of ontology
namespaces through the REST API. The imports section would corresponds
to the imports statement. The tools would count the number of classes
and properties in the ontology namespace. It would be interesting to
aggregate all this information and see which vocabularies have the
most influence using SNA algorithms.
You can also make SPARQL CONSTRUCTs against: http://lod.openlinksw.com
.. that's a massive quad store with most of the LOD cloud data sets. You
can see effect via http://lod.openlinksw.com/fct (type in pattern:
Ontology and then filter by Type or Attributes).

VOAF is of course a clear homage to FOAF, which is the hub of the network :
more than half of the listed vocabularies rely on it one way or another.
I've asked Dan Brickley a couple of days ago if he did not mind this
friendly hack. Without answer from him, I just went ahead following the
adage "Qui ne dit mot consent".
Maybe it's just Saturday morning, but what exactly is the goal of your
VOAF effort? What problems with existing ontologies does it address?
Just curious, as it sounds interesting...

Egon,
If possible, please look at the links I posted in response to
Bernard's mail.
You can also look at some of my tweets about voaf (Twitter:
hastag: #voaf) which shows how the following questions can be
answered:
1. What are the sources of terms used in a given vocabulary?
2. Who authored the vocabularies in question?
3. Which terms are most commonly used, across vocabularies, and
when where these vocabularies created?
Basically, we have a vocabulary graph endowed with de-referencable
URIs that provides an extremely powerful mechanism for holistic
navigation of the LOD cloud or other data spaces (e.g. within
enterprise intranets).
All of the above still skims the surface of what VOAF delivers :-)
