New participants were welcomed, and thanks given to Legato for hosting this meeting.  Adminitrivia was cared for by approving the last meeting minutes; discussing and adjusting the agenda for this meeting; and registering attendees.

A brief recap of the meeting in July in Boulder with members of SNIA and DMTF was given, along with a description of the consortia SNIA and DMTF and the industry efforts in developing WBEM, CIM, and Microsoft's WMI.  It was learned that Michael Thatcher/Microsoft replaces Andrea Westerinen as the  DMTF chair for CIM.

Also briefly discussed was the upcoming transition in SSSWG sponsorship.  Details are available from the SSSWG chair.

Future work after MMS .1 to .5 was discussed, with the next five MMS standards, Data Mover, scope of SSSWG's charter, the desire for a MSSRM version 6 being considered.

The schedule for the upcoming balloting was examined and updated.  Various members present promised to promote registration so that the standards will be considered by a representative ballot pool.

Status of the  present set of five drafts  was reviewed.  The consensus is that the drafts are pretty close to completion, but that there is a small set of persistently incomplete portions primarily having to do with writing examples and some input to the Architecture which is needed from editors of .2 to .5. 

Geoff and Murali brought revised drafts of the Architecture and MMP documents, respectively, to the meeting.  Change pages to the MMP, MMP model diagram were discussed as well as privileged-based constraints, derived constraints.

A long disussion was held concerning failure response mode and Murali’s MMP suggestion to use datahandles.  Curtis lead the group in a discussion of possible failure modes using the following drawing depicting potential segmentation of the MMS across machine boundaries (blue lines).

The overall result of this discussion was to clarify and document present features of the MMS drafts without making major changes.  The behavior of datahandles, for example, was heuristics, now is a test of control.  Also discussed were the 'where' clause and the multi-machine (SAN) problem and the management of control.

Bruce and Murali profitably discussed sort orders in MMP.

And the things we owe Geoff for the Architecture document (mostly nits) were itemized: writing examples, completing code examples, correct terminology, and token lists (Curtis to provide).

Geoff stated the need for a reading of all five drafts to re-synchronize them.  Don and Brian offered to do this since they each possess a fresh perspective on the drafts.  Joel volunteered Hari for this reading as well.

A renewed discussion about the case of tokens was pursued with the conclusion being that it will be stated in balloter information that case conversion will occur to make all documents conform to C-language convention.  Bruce will write VB tools to convert dducuments.

Don was invited to present virtual tape system ideas to the group, and this was accomplished through numerous small meetings.

Everyone was reminded that the March Mass Storage conference deadline is Friday August 13th.  Jack will submit an abstract reporting on the MMS work.  Geoff may re-submit the MMS tutorial.  And Curtis has a storage paper unrelated to MMS to submit.

Next Meeting.  September 21-22, 1999, Santa Fe, NM at the Hotel St. Francis.  Geoff has to attend the scalable I/O conference in Santa Fe later in the week, and it is hoped that the geographic location of the meeting may entice participants to discuss Data Mover.  This meeting will be used primarily for closure on the five drafts before handing PDF files of them over to IEEE for balloting.

No future teleconferences were scheduled, although they will certainly be held.

Future MeetingsWe expect to hold one additional meeting this year in November or December depending on the progress of balloting.
