AGENDA
Call to order
Review agenda
Review meeting minutes from 05-D meeting. Approved without change.
Liaisons:
IMS in AES: Looking for something that we can provide to them
OSA-CBM: nothing to report
Action Item Review
Lunch break, 11:40 to 1:45
Tim Davis led “sticky-note” exercise to start modeling SIMICA data.
Exercise is similar to affinity diagramming, described by Bill G. Next step would be to create an association diagram.
Joe S. briefly described his existing classification, but we did not use it.
Divided about 300 sheets among attendees, each sheet listing a SIMICA data “attribute” and a description.
Person takes his/her sheets and put them in a folder, where folder identifies a major category (e.g. Test results, UUT, test station, ...). There were 13 folders.
Each person takes a folder, review and the sheets, and potentially puts them in a different folder.
Distribute folders again, review and potentially move sheets.
Distribute folders again, review and potentially move sheets, but this time you must discuss the sheets you want to move with the group.
“Messed With” is a phrase found in several attributes on the sheets. E.g. “serial number messed with”. Tim suggested tearing them up, but we kept them.
Repair Action is a subtype of Maintenance Action
We did not distinguish between a maintenance action instance and a maintenance action procedure.
“part date code” is the date that the part was manufactured.
Meeting finished at 4:40.
Tim Davis presented an ISO 10303 Part 28 overview. Found most recent version on NIST web site, dated 2004
Darryl presented slides describing methods for validating beyond W3C XML Schema, including programming code, Schematron, and XSLT.
Tim Wilmering discussed OWL
Oscar F. presented LM's work on WSDL services. For the most part, the WSDL services do not depend on the XML Model Schemas
New services discussion:
We do not want new services that rely on the other ATML schemas, so this rules out sendTestResults.
The services “fetchDiagnosis” and “fetchRecommendedTest” make sense
Darryl presented slides on XML-enabled services. Objective to try and pass more information with each service call, building on existing services.
Extend save_exchange_model and load_exchange_model to support option of moving XML rather than part 21. Also change the parameter specified as "path" to a URI that will support save/load from “anywhere.”
show_session_trace: leave as is but tighten the spec to say that the formatted string is meant to be displayed as formatted, and not processed further. Change name to show_session_information?
show_session: (new) – dumps all session data as an instantiated DCM in XML format
show_node – the idea is that the entire XML node is returned – and in order to preserve the fidelity with the EXPRESS model an approach to constructing the 1232 XML schemas that uses XML links (refs) to represent the many to many graph relationships in the model.
show_nodeclass – no specific use case – seems useful though
The realization occurred that "get" services return things of type <attributetype> - Darryl will revisit his proposal to see if this has any effect on his proposal.
Lockheed will also revisit their service definitions based on this interpretation of the spec.
Lunch Break
Darryl presented his approach to the model schemas. He has not yet shown it to Tim Davis and John Ralph. He will discuss it with them off line.
Joe Stanco described SIMICA in general.
Software interfaces for data management systems
Models & Schemas for collecting historical data
Bottom up approach taken so far (what data is available)
Mukund M. presented the PAR for 1636.2, Maintenance Action Data. Group reviewed and edited the PAR form.
Afternoon Break
Mukund M. presented the MAF requirements spreadsheet, and the comparison spreadsheet.
Mukund presented the draft requirements document for MAF. The DMC reviewed and edited the document.
John Ralph presented the Test Results Schema. John just presented it to ATML and they pointed out that sometimes one does not know the various UUT identifier information in TR. Their discussion and ours resulted in making all the UUT identification-related data optional. The same same thing happened to the test station identification-related data.
Tim W. pointed out that Test Results, while designed as a doc description, represents the data and relationships that are available in system repositories and can be used in the API into those repositories.
Meeting finished at 5:40
Wrap-up of discussions
Darryl said that the services need to be reexamined, given the agreement that services can pass structured entities.
Bill G. presented relevant MIL standards to SIMICA
Agenda for 06B was approved by the committee.

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: OPEN Medium Priority
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.
