Date: Feb 7, 2005 2:00pm EST

Attendance: Dan Marcus, Yong Gao, Heidi Schmidt, Tony Lissot, Tim Clark, Georgios Asteris, Hans Breiter, Dave Kennedy (Did I miss anyone?)

1. We will be using the mBIRN/NAMIC wiki site (http://www.na-mic.org/Wiki/index.php/XNAT) for ongoing discussion and documentation. Use of this facility is essential to assist in the development of the necessary documentation for XNAT.

2. Hans provided brief background of PGP project to Dan Marcus. Additional information (executive summary, etc.) will be provided to Dan to help them understand the overall structure and goals of the PGP project.

3. A mid-level XNAT system description will be developed, to assist potential users of the XNAT system in understanding the nature, design and implementation practices employed in the system. Dan and Yong will continue this discussion off-line.

4. Hardware/software requirements were reviewed. The initial 'installation memo' was reasonably complete in the requirements. Additional dependencies will be packaged into the XNAT distribution itself, and will not require preinstallation.

5. Approach to Installation. Multi-phased approach.

Phase I: MGH test of WashU sample app (Notes: schema stays same, only installation site changes; this to initially be database generation tool, with it's xml schema and test data; web app testing is still approx 2 weeks away; MGH will concurrently test Postgres and Oracle versions)

Phase II: MGH will prepare sample xml data models for PGP specific data (subject, structural imaging, functional imaging, diffusion imaging, ASL imaging, behavioral testing, etc.). These models will also be tested at WashU to provide feedback on the generation code. (Note: for WashU testing, installation stays the same, only data model changes).

Phase III: MGH will continue local implementation of PGP data requirements at MGH.

6. Action Items:

a) Dan to provide sample schema and data and database generator to MGH (Yong/Heidi)

b) Yong and Heidi (and Georgios?) to test the generation functions.

c) Tony to provide existing schema (xml?) of the database structure he's already using

d) Dave, Tony, (with help from many others) to create initial data models for structural and functional data requirements

Agenda:

1. PGP-extensions to oasis sample

sample data conforming to this schema

Reviewed the specific extensions that have been proposed from PGP standpoint, and that the new XSD has been tested through the generator and with 'fake' sample data.

Work is ongoing to prepare a data document with real PGP data, first for one subject, to test; then with mulitple (~10) subjects for further testing. This involves work on formating the output of local programs to export data in the necessary XML format.

Issues regardinging what namespaces should be used arose. Dan will review the proposed changes and suggest what changes should be part of the base XNAT namespace, versus which elements belong in a PGP extension namespace.

Ways for checking XML validity were discussed (rxp, Xerces, smlspy, etc.). Where should be ways for data files to be checked prior to upload; there will also be some checking as part of XNAT.

Over the next week, this sample data will be finalized and loaded.

2. WebApp... Dan discussed the general form of this a bit; including XML display documents related to each element in the schema. Disucssion of the difference between listing pages and report pages was introduced.

Since this is not well described in the current MGH example, Dan will prepare some documentation on the process, and review some examples of how to control the Webapp, so that the MGH group can begin to see how this will work.

Over the next week, this information will be sent to MGH.


3. Documentation Yes. It is needed. What ever can be generated should be. As questions arise, they should be sent to Dan, so that he can both answer them, and prepare a FAQ.


4. Dan Visit to MGH

Tentitive: April 27-29


5. Other things... 'Standing' weekly teleconference on Mondays at 1:00 (EST) for ongoing dialog.
