   approval of minutes

   our next F2F is 18-20th April in Edinburgh, will send out logistics

   planning for Wed-Thurs to be testing, Friday to be processing issues
   and the documents

   pauld: please look to the Action Items list, it's out of hand!

ISSUE-2: test suite

   yves: can we distinguish between examples we exclude beacuse of barf
   dancing and those we exclude because of broken examples?
   ... we also have some broken instance documents

   pauld: please make sure you don't commit broken instance documents!

   yves: need reviewing

   <Yves> http://www.w3.org/2002/ws/databinding/examples/6/09/

   <Yves>
   http://www.w3.org/2002/ws/databinding/examples/6/09/DateSimpleTypePatt
   ern/#DateSimpleTypePattern02

   <Yves> this one is easy to fix

   <Yves>
   http://www.w3.org/2002/ws/databinding/examples/6/09/AttributeReference
   /AttributeReference-AttributeReference01.xml

   <scribe> ACTION: gcowe to review and fix instance documents which fail
   validation [recorded in
   http://www.w3.org/2007/03/20-databinding-minutes.html#action01]

   <trackbot> Created ACTION-121 - Review and fix instance documents
   which fail validation [on George Cowe - due 2007-03-27].

   <Yves>
   http://www.w3.org/2002/ws/databinding/examples/6/09/AttributeReference
   /

   yves: telno has to begin with a '0' and yet it's an int

   pauld: we started out making the element and attribute names human
   readable, but I think we've learnt that it's not clever to make an
   attribute name "telno", we should make it "integerAttribute" or some
   such to avoid semantics above the type

   yves: looks like a toolkit problem after all
   ... we need to do a re-run

   pauld: wondering if it's still realistic to publish the report is
   ahead of the F2F

   yves: having to do lots of caching,
   ... needs more cosmetics

   pauld: main concern is the accuracy

   yves: we have tests marked as failed, need to be sure it's not my
   comparison

   gcowe: on the failures - are you deciding by looking at the HTTP
   response, body?

   yves: just comparing SOAP envelope

   pauld: the perl captures the HTTP headers for extra info, but a
   standalone Java command would be better for those who don't understand
   the ways of CPAN

   gcowe: working on such a thing

   pauld: each toolkit has a
   http://www.w3.org/2002/ws/databinding/edcopy/toolkits/php5_php_5.2.0/t
   oolkit.xml
   ... contains per-toolkit info for the report
   ... and a list of examples to exclude, some are because of the
   examples are broken

   gcowe: I'd like to test just basic or advanced patterns

   yves: i've managed to do this in dashboard.java

   gcowe: spent too much time on the barf dancing and excluding tests,
   now working on building the output.xml file from a Java command

   pauld: would like to wrap this work up as a zip file so others can
   supply tests with their own toolkits

   yves: george, you can edit the makefile to add your tests to the
   report

   pauld: have a couple of tests up my sleeve from non-java kits
   ... thanks for all your hard work, I need to catch up with it

ISSUE-12: identifying a conformant schema

   pauld: nothing to report here, sorry
   ... interesting news from IBM:
   http://www.alphaworks.ibm.com/tech/purexml
   ... looks like work around the databinding for DB2
   ... does anyone have DB2 experience/expertise?

   gcowe: have some experience, but not using it currently

   pauld: haven't quite understood it, yet, looks interesting for us

ISSUE-103 - Cyclic References

   jonc: wondering about raising more complex issues around this issue
   ... has some Java to test this, should we be looking to reuse this -
   as a post-processing step?
   ... views anyone?

   gcowe: haven't yet looked at the java code you sent me

   jonc: same issue applies to extension and element reference

   pauld: valid issue, rasied at the original workshop, but how do we
   test it, do we need Java?

   jonc: we could add this to the Java command which tests a schema

   pauld: other tests we could add for assertions, eg. UTF-8
   ... is this a pattern or an assertion?

   jonc: I'd like to see this tested for as it's easily added almost by
   accident

   http://www.w3.org/2002/ws/databinding/edcopy/basic/basic.html#assertio
   nsummary

   pauld: note Philippe also added a useful appendix on the schema types
   and elements used within Basic and Advanced patterns

   jonc: could be useful to cite the other examples

   pauld: think we could write something generically around the component
   model
   ... suggest adding the same constraint to the other examples
   ... is this for Basic or Advanced?

   jonc: pathalogically cyclic dependencies shouldn't be Basic
   ... e.g mandatory links
   ... with minOccurs="1"
