:-) Absolutely fine with me. I'll soon (hopefully this evening) submit
an update which also covers OWL RDF-Based Semantics and the OWL RL
profile. All the RDF-Based entailment regimes are very similar, just
OWL Direct Semantics is a bit different. I hope RIF can be handled in
much the same way as the RDF-Based regimes. Maybe you can have a look
at the document and then either just start or we can discuss the
options for RIF in a teleconf for those interested in that.
