Agenda
- GLS status report
- GLS client report (would like to cover the xsd/geotools/OGR issues in here, security as well)
- IE testing requirements
- Performance tests
- OGC Liaison
- Consortium Agreement
- Dissemination, eg, AHM
- AOB
Notes
- GLS status report
  - XSD holds all attributes for GDAS and GeoTools seems to have problems with this:
    - Andy to try and find out who maintains GML stuff in GeoTools and liaise to see if this is a GeoTools problem or a GML specification peculiarity (probably a GeoTools implementation issue).
  - OGR being embedded with OGSA-DAI in the server.
  - Convert activity with OGR using streams a potential for OGSA-DAI.
  - WPS status documents being used for tracking progress.
- GLS client report (would like to cover the xsd/geotools/OGR issues in here, security as well)
  - Images working for canadian data
  - Malformed XML
    - XSD request document from OGC should help
  - Paul happy to plug away and try to get the GML rendering with GeoServer/GeoTools working.
- IE testing requirements
  - We should report on the wiki what we find out.
  - Paul already identified a couple of issues with Canadian GLS Client
- Performance tests
  - Feedback on email from Michael... Need to look at this again...
- OGC Liaison
  - WPS subject to electronic vote for full implementation specification.
  - We are unsure about the GeoLinking WPS Profile status
  - Gail asks about implementing OGC Catalogue CSW as she is looking into this for satellite data
    - GeoNetwork implementation advised as a ISO19115 application profile (reference implementation)
    - There is crossover here with a Geospatial WG meeting...
    - Chris going to help Gail by writing an email summarising EDINA CSW work.
      - That's great!
- Consortium Agreement
  - Alison Turner Keen to get this tidied up
- Dissemination, eg, AHM
  - Chris arranging with Alison Turner to do a demo on JISC stand.
  - Ally will point to this from OGSA-DAI end.
- AOB
  - OGSA-DAI scalability issues that Pascal identified.
    - Concerns raised about not being able to track how issue being dealt with.
  - Mid Project meeting to take stock of what we've got
    - Chris to circulate some dates.
  - Security
    - Junaid Arshad at Leeds working on Shibboleth installation with GridSphere.
    - John initiating a federation for this on the back of doing the same for other projects.
    - Fiona Culloch of SDSS available for providing advice.
    - Other countries moving to use Shibboleth.
    - Permis for authorisation type security on the back end servers.
    - Shibboleth for filtered views of the ack end service at the user end.
    - John to do a survey about this.
    - Creating a policy to explain needs on a project is the harder part:
      - One way to do this is generating an XACML document.
      - Noted that there is a GEOXACML - a geospatial extension to the OASIS standard eXtensible Access Control Markup Language (XACML).
    - Implementing a policy is the easier part.
    - WPS Vanilla http requests
    - WPS SOAP requests
    - GeoRM
    - Gate keepers...
    - VOMS
      - John looking at how Permis fit with this:
        
        VOMS have their own certificates X509 certificates with an extra bit on the bottom saying you can do a,b,c.
      - EGEE and Terragrid using VOMS?
  - Chris well report back to us on a follow up meeting from OGF20 in Paris.
  - Andy to send round feedback from Ken Miller email.
  - Next meeting Friday 27th July
