I will (probably) miss tomorrow's teleconference also.

Update about PROV-SEM: 

I have been working on converting the various rules to LaTeX-style rules to the wiki page:


Most of them are now done; the exceptions are the key constraints and definitions.  I am leaning towards dropping the definitions from the formal model (since they are really about syntactic desugaring) and simplifying the formal model by factoring attributes into a separate relation (or relations, one for each "type", since an id can be both an agent and an entity, with separate attributes in the agent() and entity() statements). Then a lot of attrs parameters go away, and the KEY constraints really are functional dependencies.

It would be helpful if others could have a look at the LaTeX-ified rules in case typos have been introduced.  Also, if anyone that has a better idea about how to convert this into W3C-note-style HTML than brute force, that would be great.  I believe it is realistic to project that the wiki version will be stable by December 19th (when I leave for the holidays), so it would be useful to line up potential reviewers or people to help with conversion now.  I think this work is parallelizable, but it might be a better use of time for me to spend a couple of hours hacking up a simple way to generate the rules from something higher-level, that could be targeted to HTML or TeX or whatever else.
