TRSI Standard - Report on Progress Towards Ballot
John Ralph joined the meeting via telecon. The ballot invitation is out. An email was sent to the ATML/TII group letting them know about the ballot invitation. The invitation has been extended to 45 days rather than the usual 30 days. The ballot invitation closes October 30. MEC will provide another set of comments between the close of the ballot invitation and before commencing the ballot.
There are some editorial comments from MEC. The comments are more related to format than content. All changes are in, and the new template has been used. This will be very helpful when publishing.
AI-ESTATE Draft Review
Model Changes
The model changes were reviewed with particular attention given to why the hierarchical element is being eliminated/re-done.
Entity Definitions
The definitions for the Common Element Model are proceeding well. They will be presented to the group following completion of the work by the ad hoc working group.
XML Service Review
Lockheed-Martin has taken the March model and created WSDL services for that model. Obviously, these services will change when the model changes. The service definitions are being updated as the model updates; they are being worked in parallel.
Prognostics Annex Review
Pat Kalgren presented a paper at AUTOTESTCON on information requirements for prognostics with the hope this would be used to help develop the prognostics annex. A lexicon for PHM exists. It would be nice if we could use it. Unfortunately, people don't agree on what the definitions of PHM mean. Pat will provide his paper as a log item to be used for extracting an initial set of definitions for the annex.
Conformance
Darryl, Tim, and John still need to work on this. Nothing to report here.
SIMICA Discussions
SIMICA Architecture and Document Structure/Content
A rough version of the SIMICA information model was presented.
One of the questions raised was whether or not to use the 1232 DCM for diagnostic session information. Alicia noted that they save out the DCM information and believe the information is sufficient for capturing this type of information for use in SIMICA.
There is also a question about whether there are elements in the DCM that should be separated out (or replicated) in a SIMICA schema to represent the diagnostic session data that needs to be archived/stored but would not carry with it a large amount of additional information specified by AI-ESTATE.
MAI Status
The requirements document is under development and needs to be approved by the subcommittee prior to sending to Admin. Mukund was confirmed as the chair of the MAI working group.
Talked to SMEs to develop use cases. These led to modification of the schema. Some instance XML documents against the schema to validate the use cases. This led to some modifications to the schema.
The MAI requirements document was reviewed and revised. A motion and second were made to approve the revised requirements document. It was approved without opposition and will be submitted to Admin for review.
The schema was reviewed.
Final Discussions on All Topics
Roadmap was updated.

Status: OPEN
Action
Item 06C-4: Pat Kalgren to use his AUTOTESTCON 2006 paper to
start developing a prognostics annex for 1232. This paper will
provide a set of definitions as a starting point.
Status: OPEN
Issue 01C-1:
Testability metrics based on maintenance philosophy, such as Fault
Resolution, can provide a means of validating predictive measures.
At this point, the information models used to support definition of
metrics in P1522 are insufficient to address maintenance philosophy
– it is hoped that this deficiency can be addressed in the
future through the creation of the SIMICA information model. Moved
to SIMICA.
Status: OPEN Medium Priority.
Issue 02A-1:
Log # 335 – a draft version of the False Alarm Appendix
(Annex) submittal contains several sections enumerating metrics for
False Alarm and Assurance Tolerance. These metrics are to be
considered for later inclusion in the standard – after we have
formalized the definitions of False Alarm metrics. Moved to SIMICA.
Status: CLOSED, OBE
Issue 03C-2:
Committee will examine STEP standards to determine if/how part
identification is modeled relative to system indenture
identification.
Status: OPEN Medium Priority
Issue 05D-1: Higher order
services will be needed for each of the principal standards under
development within the DMC. These services include traversal and
analysis support of the static models. For example, Qualtech
proposed at the 00-B meeting the addition of a new service,
get_test_outcome_from_diagnosis(diagnosis, set of test). This
service allows user to get the test outcomes predicted from the
seeding of a particular diagnosis (fault). This corresponds to a
lookup of the fault in the test-diagnosis (D-matrix) matrix.
Status: OPEN Medium Priority
Issue 06C-1:
IEEE Std 1522 is not currently being used. Need to examine reasons
for this and determine the future of the standard. Some
possibilities to examine include: Does it a need management
component (ala MIL HDBK 2165)? Are metrics too inaccessible due to
tie to 1232? Is it simply a publicity/perception issue? Is there
resistance to objective accountability? Discuss with program
managers (Russell Shannon—NAVAIR).
