Issues requiring clarification --------------------------------- Summary of progress from last week: Issues still to resolve: 1128 http://www.w3.org/Bugs/Public/show_bug.cgi?id=1128 Summary: Accessing and modifying members of lists and arrays URL: http://www.w3.org/TR/2004/WD-ws-cdl-10-20041217/ GB: http://lists.w3.org/Archives/Public/public-ws-chor/2005Mar/0013.html PROPOSAL: PROPOSAL TO CLOSE WON'T FIX and add text to primer Basis: To properly modify information (lists/arrays/xml documents) in concurrent threads requires a level of isolation/synchronization, and CDL only provides a coarse mechanism for this - so would prefer to leave these modifications for ***silentActions***, which can then implement any necessary synchronization. We should not really be adding further activities that make this a more turing complete language. Thus silentActions can be used as a suitable silent mechanism for accessing and modifying lists and arrays and therefore we do not need explicit support in WS-CDL to do this. The primer should include an example of how this might be done using WS-CDL, silentActions and a suitable end point language. FROM Comment 2 attached to bugzilla issue Other issues: Why do we have so many places in which we declare relationships and roles? e.g. "participate relationhip", "channel types" 9. AOB -------
