1. Current Actions
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
...
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.
10/03: work is progressing
17/03: work is progressing
31/03: work is progressing
14/04: And XML test case format has been defined and is being tested.
21/04. Schema for TDML defined. Need to define how this and the test cases
will be made public
05/05: Work still progressing
12/05: Work still progressing
02/06: Work still progressing on technical and legal considerations
...
25/08: Will chase to allow Daffodil access to test cases. The WG should
define how implementation confirm that they 'conform to DFDL v1'
01/09: IBM still progressing the legal aspect. Intends to publish 100 or
so tests as soon as it can, ahead of a full compliance suite.
08/09: IBM still progressing
15/09: IBM still progressing, expect tests to be available within a few
weeks
22/09: IBM still progressing, expect tests to be available within a few
weeks
29/09:Test cases are being prepared.
06/10: Some test cases should be available next week. Steve would like to
be able to show the test case information at OGF 30.
13/10: Still progressing
085
ALL: publicise Public comments phase to ensure a good review..
14/04: see minutes
21/04: Press release, OMG and other standards bodies.
05/05: Alan and Steve H have contacted other standards bodies. Will ask
them to add comments on spec
15/05: still no public comments
02/06: No public comments
16/06: Public comments period has ended with no external comments. Alan
had posted changes made in draft 041. Steve suggested send a note to the
WG highlighting these changes. Steve also suggested requesting an
extension as other IBM groups may review. We discussed whether this was
necessary as changes will need to be made during the implementation phase
anyway. Alan to ask OGF what the process is for changes post public
comment.
23/06: Still no comments. Alan will contact OGF to understand the rest of
the process.
30/06: Alan has emailed Joel asking what the process is now public comment
period is over and can we update the published version with WG updates. No
response yet.
07/07: No response. Alan will chase up
14/07: No response from Joel. Sent email to Greg Newby by no response.
21/07: Still no response.
04/08: Joel has responded that it is up to the WG to decide if the changes
are significant enough to need additional review. Alan to contact David
Martin and Erwin Laure for guidance if we split the specification.
11/08: Received a response from Joel that the WG can decide if a re-
public review is necessary before becoming a 'proposed recommendation'.
Alan responded that the WG agreed that a re-review was not necessary. The
next stage is for OGF review committee to approve publication.
11/08: Specification is now 'awaiting author changes' before being
submitted to the OGF technical committee for approval as a 'proposed
specification'.
Alan would like to have the updated specification complete by Sept 10th.
The WG needs to complete all actions by then or decide that they do not
need to be included in this phase of the process.
01/09: Alan and Steve have discussed and propose Sept 30th for completion
of draft 43 and closure of all actions.
08/09: Target for completion September 30.
15/09: as above
22/09: as above
29/09: Draft 43 will be published this week for WG review prior to
submitting to OGF
06/10: Draft 43 was distributed on 30 September and includes all
outstanding work items. This will be the last draft before submission to
OGF for the final committee review. All comments should be sent to Alan by
Tuesday 12th Oct and final version will be submitted on Friday 15th.
13/10: Thorough review by Steve and comments from Suman and Stephanie.
Most updates done. Final review draft will be issued 14th Oct and final
version to OGF soon after.

Daffodil DFDL parser
11/08: Bob and Alejandro described the new implementation that they have
developed. It is a new code base and is not based on the Deffudle
prototype. It is written in scala and implements approximately 80% of the
features in the public comments draft of DFDL V1. Alejandro will send a
list of the features not implemented.
We discussed the scenarios that motivated the development which was to
extract data from various sources and transform into canonical formats.
Bob offered to make Daffodil available for the WG to assess the
functionality. IBM WG members will get approval the company to allow them
to receive Daffodil.
Bob raised the question that if Daffodil becomes the public implementation
of DFDL then we will need to work out how that would be funded and
managed.
It would be helpful if IBM test cases were available to Daffodil. IBM will
investigate
25/08: Alejandro had sent a list of the functions that he has implemented
and Steve ahd responding indicating the extra functions he thought were
essential.
Since then Alejandro has implemented some of the missing functions, such
as escape schemes, pre-defined variables, binary decimal numbers, etc, and
will update his list.
Bob is planning to make the parser available on the internet to allow
testing.
His organisation is being reorganised and he doesn't know what the
priority of Daffodill will be so it is essential that we move quickly. It
would help if IBM could indicate its support for Daffodil in some
semi-formal way.
01/09: Alejandro updating Daffodil to include escape schemes, unordered
sequences and ignoreCase.
Daffodil being placed under formal source control in anticipation of
external release.
Bob has a start October deadline to create a report on what has been done
for his sponsors.
It would be great if we could get Daffodil on the web and have run some
IBM tests so it could be highlighted at OGF 30 at end October.
08/09: Alejandro is marking up Spec draft 42 to indicate which features
Daffodil implement. Bob expects Daffodil to be available on the web soon.
15/09: Alejandro had indicated in the specification which functions were
implemented in Daffodill. Steve had reviewed and identified which function
need to be implemented and which could be considered optional (see action
099). Alejandro is implementing the missing core functions. There was some
discussion about the limitations on unordered groups. (stop value and
expression not supported). It was agreed that it should be a schema
definition error if dfdl:occursCountKind is 'stopValue' on any element
within an unordered sequence and a floating element.
22/09: not discussed
29/09: not discussed
06/10: Alejandro has left NCSA. Bob is making the case for continuing and
having a replacement. Bob to agree with Steve what can be said at OGF30.
13/10: Bob still progressin project funding and making Daffodil publically
available.
112
DFDL certification process
25/08: Discussed how to certify DFDL implementations. Alan to investigate
if OGF have a defined process.
01/09: In progress, spec needs to state what conformance means, as part of
this work
08/09: Discussed what needs to be said in the spec and agreed that details
of a conformance test suite should be in another document.
Alan to draft conformance section.
15/09: Alan had look at the conformance sections in XML and Schema
specifications both of which indicate sections which must be implemented.
None just say 'execute the test suite'. They talk in terms of conformance
of document, schema and processors..
22/09: no progress
22/09: Alan has added short Conformance and Optional Features sections to
spec which was briefly discussed. Discussed naming for processors that
don't implement optional features and those that implement all features.
06/10: Need to decide what/how test cases and certification process should
occur
13/10: no progress
123
DFDL tutorial
13/10: Draft of first 3 chapters has been written and will be distributed
to WG
124
DFDL web content on OGF standards pages
13/10: no progress
125
-p111 13.16 nilValue literalCharacter. If not fixed length how many should
be output? Steve to check what MRM does.
126
-p85 13.2.1 generateEscape really only applies to escape blocks so could
be renamed.
127
3. dfdl:roundingIncrement
Problems with rounding and ICU
13/10: not discussed
128
5. AOB - Is support for locales sufficient?
13/10: not discussed
