Agenda for OGF DFDL WG call 10 March 2010- 13:00 UK (8:00 ET)

1. Spec issues documentFinalTerminatorCanBeMissing: Let's try to avoid creating another property for the postfix separator scenario. I think this property provides a way of modelling the data naturally. We can recommend use of infix-with-a-terminator rather than 'postfix' if the final terminator can be missing. We didn't come to a conclusion on the alst WG call. dfdl:lengthKind endOfParent 'endOfParent' has almost the same meaning as 'delimited' so should have the same semantics. · the item?s terminator (if specified) · an enclosing construct?s separator or terminator · the end of an enclosing construct designated by its known length · the end of the data stream The effect would be the the element could be ended by the nearest known length parent not just the immediate parent. Also the immediate parent could have lengthKind 'implicit' dfdl:lengthKind endOfParent LengthUnits 'characters' is currently for simple representation 'text' only. Should it be allowed for complex? Selectors Should they be moved to an appendix. DFDL Expression Syntax Value comparison operators are 'eq' 'lt' 'gt' etc not '=' '<' '>' because these were defined poorly in XPATH v1 and replaced in XPATH V2. Unfortunately most examples us '=' etc Syntax of expressions in string literals. Add A DFDL string literal which begins with { and does not end with } does not need to have its leading { escaped. IgnoreCase Should ignoreCase apply to numberInfinityRep and numberNaNRep Escapes. Should escapeCharacter, escapeEscapeCharacater etc allow DFDL expressions. 2. Current Actions: No Action 066 Investigate format for defining test cases 25/11:IBM to see if it is possible to publish its test case format. 04/12: no update 09/12: no update 16/12: reminded dent to project manager 23/12: SH will send another reminder. 06/01: Another reminder will be sent 13/01: no update 20/01: no update 27/01: no progress 29/01: no progress 03/02: IBM is still investigating 10/02: IBM is still investigating 17/02: IBM is willing in principle to publish the test case format and some of the test cases. May need some time to build a 'compliance suite' 24/03: No progress 03/03: Discussions have been taking place on the subset of tests that will be provided. 080 AP:Clarify semantics of fn:poisition and fn:count 17/02: no progress 24/03: No progress 03/03: no progress. There are other functions which return a duration which need investgating 3 Status of specification (for OGF28) Alan Powell Development - MQSeries, Message Broker, ESB IBM Software Group, Application and Integration Middleware Software ------------------------------------------------------------------------------------------------------------------------------------------- IBM MP211, Hursley Park Hursley, SO21 2JN United Kingdom Phone: +44-1962-815073 e-mail: alan_powell@uk.ibm.com Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
