OIW ODA SIG REPORT March 9-11, 1993 10 attendees, plus 4 for the tutorial Highlights: - Discussed Application Portability Profile (APP) reference to ODA and SGML. - Discussed need for new SIG for content architectures, recommendations will be available. - Approved changes to Parts 22 and 23. - Progressed Part 27 for migration DAP from FOD26 to FOD36. Technical Activities: * Image application subgroup: - Approved a technical change to Part 23 (ODA Raster DAP) to modify the "application comments" attribute. - Approved editorial change to the value for "ODA-version" in both Part 22 and Part 23. - Prepared liaison statements to DoD and AIIM concerning changes to the ODA Raster DAP. - Prepared PAGODA 13 contributions: 1) Revisions and additions to FOD112 pDISP; 2) OIW ODA SIG position on development of FOD126 pDISP; 3) urgency in publication of ISO 8613. * Text processing subgroup: - Reviewed and provided comments to workshops on the proposed ISR proforma from EWOS - Reviewed and revised level 2 to level 3 migration DAP. This DAP will be Part 27 of the working agreements to be used to help generate a migration ISR for FOD36. - Prepared contributions for PAGODA 13: 1) comments on ISP Proforma proposal from EWOS; 2) general requirements for ISR Proforma; 3) Position on conformance testing; 4) position on ISP enhancements. * Interoperability subgroup: - Reviewed testing methodology technical report. - Reviewed fidelity criteria for evaluating I14Y quality. - Reviewed project budget and new sponsorship proposal. - Reviewed new product directions, possible future I14Y testing needs. - Discussed change of technical consultants. Meetings: OIW ODA SIG - Gaithersburg, MD 6/8/93 - 6/10/93 PAGODA #13 - England, 3/30/93 - 4/2/93 ========================================================= Minutes of the CATG Meeting from: Jon A. Stewart, Acting Chair March 10, 1993 4:30-5:30pm Attendees: ODA SIG Members Carlton Neville, Neville Associates Lynne Rosenthal, NIST This was the third meeting of this CATG; and many of the topics previously discussed were revisited, including: o Required capabilities of a "wrapper" or interface from content to "the world" (applications, formatters, document architectures) o Critical requirements for preserving information content (objects) for long durations (e.g., 50 years for Boeing aircraft documentation) o Independence and neutrality of content objects to various applications -- e.g., potential use of a a CGM content object in both an SGML documents and an ODA document o Difficulty (some said impossible) of describing all the processing methods (such as layout, imaging) required for particular content types o Interaction of content types, e.g., character text content within a CGM content object o Need for independent content profiles -- such as those being developed for CGM, in CALS and elsewhere Although this has been useful brainstorming it does appear that there is no great interest from the current members of the OIW (including those members of the ODA SIG) in continuing the activity, either as part of the ODA SIG or as a separate SIG. The profile requirements for CGM in particular are being handled nicely with the current process. As new content types (such as audio,video, other character content than that described in ODA -- e.g., Unicode) become more important then interest may grow and justify the formation of a new SIG. We will meet one more time (at least) at the next (June) OIW and decide whether to continue this activity or redirect it through some other possible SIG (e.g., Information Interchange, Multimedia Content, etc.). ======================================================= OIW/ODA 93/0319 To: Mr. Bill Gorham CALS Integration and Evaluation Office Mr. Alan Peltzman DISA Ms. Jean Baronas AIIM Mr. Jim Crawford CALS Industry Steering Group From: Mr. Jon Stewart Acting Chair, OIW ODA SIG Date: March 12, 1993 RE: Revisions to ODA Raster DAP, Stable Implementation Agreements At the March 1993 OIW meeting, the OIW/ODA SIG approved revisions to the ODA Raster DAP in NIST Special Publication 500-206, Stable Implementation Agreements for Open Systems Interconnection Protocols Version 6 Edition 1, December 1992. The "application comments" attribute now consist of two fields. The attachment describes the specific changes. This action was necessary to align the DAP with the International Standards Profiles (FOD11, FOD26, FOD36). The error was detected during verification of the ODA Raster DAP using the ODA Conformance Testing (ODA-CT) tool. In addition, the value of the "ODA version" attribute was changed according to actions approved by International standards bodies (see attachment). This action is necessary to properly reference the joint CCITT/ISO publication of ODA which incorporates the tiled raster graphics and additional bit order mapping addenda. Sincerely, Mr. Jon Stewart Acting Chair, OIW ODA SIG
