Big Agenda Item: DAML+OIL release

Frank's open issues: 

Ian has already sent around the new language definition a few weeks
    ago.  He wrote a new version of the walkthrough and also updated
    the example file to match it.  He wrote a description of the
    language elements described in english. Only feedback from Ian and
    Peter.  Two versions of the reference file, short and
    long. Suggests that we remove the short version and use only the
    long as a single reference document.

How to deal with lists, hiding content (avoiding exposed content),
    domain and name restrictions as inherited from RDF schema. 
    
    First ... how to deal with lists.  Dan invented a new parse type
    "daml:collection" which is a shorthand for list notation.  This
    will parse but it will just get thrown out.  Do we go with this or
    make life easier for tool developers?  Ordered but ordering not
    relevant in the collection notation.  Will order ever matter?
    ... long discussion ...  Requests to do this outside of the
    telecon!!  Could this just be a naming issue?  We need to make
    sure we don't break rdf parsers even if they don't understand it.
    Lets break on this and come back with some info on this and pros
    and cons for next week!!  Dan and Stephan will contribute before
    next weeks telecon.

    Next ... avoiding exposed content.  We are ok except with
    cardinality.  New syntax to fix this ... looking for an ok from
    the group.  Mike says that most people are probably more
    interested in avoiding exposed content in instances.  Two options,
    one is more useful.  Complaint about numbers being strings.  We
    have syntax for numerals, but not integers.  (numeral is "1111").

    Third ... Domain and range restrictions. In or Out?  If we want max
    compatability with RDF schema then we need to leave then in, but
    RDF Schema is already broken (but we assume / expect it will be
    fixed).  Put in the walkthrough to be careful with their use
    (maybe deprecated) but do not completely cut them out.

Any thing else holding up the release?

Frank: KIF core -- SUO KIF Not well defined so far.  Dont think we
	should do too much with this because it might be a working
	group.

ACTION ITEMS:
Frank:  Replace the reference long and short with just ref.html
Dan and Stephan:  Prepare list proposals before next week
Frank: exposed content - footnote addition
Peter and Deborah: updating for DAML+OIL for domain and range
Frank: Add comment to be careful with domain and range
Frank: Add note about no concrete types in this release
Ian: When using same property as can be used in both directions
