Yes, it seems straightforward and important.  But a thought occurs.  

Should we go in the direction of creating non-thread safe flat files and reinventing the thousand little patches already sewn into full-featured wikis like Wikipedia?  Is your objective now to create a maximally useful and scalable product?  If yes, why continue past proof of concept in framing AceWik in Echo if it can instead be fully clothed in e.g. MediaWiki (www.mediawiki.org/)?

But it's also very useful to describe something that may or may not be present.  I don't know where regular expressions fit on the expressivity scale vis-a-vis predicate calculus, but it's sometimes better to search for todos with "to ?do" rather than "to do" or "todo".  And if one want to describe what the world may contain, do we have to settle for "the world contains elephants and eggplant and ..." and make guesses as to whether the world is closed, or can we simply communicate that "The world is all creation, at least 0 Creators, and nothing else"?

Adding Oracle's demo tables emp and dept (http://www.psoug.org/reference/insert.html) into AceWiki yesterday, I noticed that in some sentences it was clearest to refer to the tables as "demo.emp", sometimes as "emp table", etc.  I think maybe instead of just having abbreviations (a nice feature by the way), each proper noun should have a user-defined set of synonyms, and that clicking a proper noun while in Edit mode drops them down and allows any to be chosen.  Regardless of which is chosen, Attempto continues to see each proper noun's fully qualified "headword", or first representation, only.

Also, how would you continue past "Every key column has at most 1" to add "instance of a value"?

thank you,
