"Seegrid will be due for a migration to confluence on the 1st of August. Any update on or after the 1st of August will NOT be migrated"
This project journal is for the benefit of sponsors and other interested parties to the AusIndustry/MCA Information Services Roadmap project. The project is being carried out as part of the SEE Grid Community as there are many components, particularly the WFS implementation work, that will benefit other members of SEE Grid outside of the project stakeholders.

The Geoserver community (in particular the Geotools portion) have been presented with the initial ideas on adding Community Schema Support and Complex Types.

RobAtkinson reports an active engagement has been built with full day coding and release strategy planning activies occuring.

The ground work for development has been done and the Geoserver build environment is working. Once the strategy is clear coding will begin.

Project Schedule Modification for Part B - Geoserver Component

RobAtkinson approached me earlier in the month with a request to modify the project schedule. The primary reason for the change it to align the Roadmap project development schedule for adding Community Schema support with the release schedule for Geoserver (or more correctly Geotools). It was originally intended that the geoserver work being completed by June 30th 2004. The release schedule for Geotools is July 2004. In order for the Community Schema support to be incorporated into Geoserver (and thus become part of future releases) it is necessary to align the schedules.

The principle sponsor for this particular stage of the work is Geoscience Australia so after discussion with LesleyWyborn the schedule was modified to ensure the Community Schema support would be incorporated into Geotools. No additional effort is expected as a consequence of this. It is a matter of ensuring that the development team carries out its activities at the appropriate time to ensure the code can be incorporated.

Project Note for Part B - Demonstrator Component

As a consequence of the change in the Geoserver component schedule RobAtkinson has brought forward some early activities associated with the demonstrator component. In order to allow greater feedback and visibility for the demonstrator development a development server is being setup to host deployed versions of the demonstrator as development proceeds.

For those of you who will be deploying at your own sites the basic setup is:
  • Tomcat 4.1.x where x >24
  • JSDK 1.4.1 (latest is OK)
  • Java Advanced Imaging (JAI) installed
  • Web Map Composer from Social Change Online

The system is actually a vmware GSX server virtual machine which adds the rather nice ability to "snapshot" the entire machine at a single point in time. Think of it as an UNDO capability for all your hardware and software. This means a snapshot can be taken prior to the next build or test being performed and the entire server rolled back if (or should I say when given this is development work!) things don't go quite as planned.

The plan is to:
  • Drop in two example WMC builds - using GML/WFS concepts - one for Ordnance Survey and one for Murray Darling Basin Commission - these will give a sense of what might be achievable in the demonstrator phase.
  • Geoserver war file - which will be progressively updated with Community Schema support
  • Some shape file data sources
  • configure geoserver
  • test remotely
  • create war file for WMC with a preconfigured view to exploit the geoserver install drop in this WAR file.

The details are still being worked out but it will be made accessible to all project stakeholders as soon as possible. In addition, technical team members can request login privileges to access the server directly and try things out (like additional data sets).

Progress Report 01 Jul 2004

The development of a reference WFS implementation is in train. To date, much of the activity has involved taking advantage of the engagement of key developers working in related areas.

Engagement has inluded:

This has engagement proved highly necessary and somewhat prolonged for several reasons:
  • significant changes in code base consistent with our needs are already underway
  • the practical experience driving our abstracted approaches has taken quite a deal of explanation (but a high level of acceptance has be achieved as a result of this effort)
  • other business outcomes are being planned that would impact on our approach
  • the code base has become significantly more complex in recent times and documentation has not really caught up with it

In addition to this design activity, the following tasks have been completed:

  • creation of development environments from CVS and subversion repositories of GeoServer and Geotools
  • successful build and compilation
  • preliminary tests of "off-the-shelf" geoserver with local sample data
  • successful establishmemt of a map view using geoserver with WFS query and SVG rendering pipeline within Web Map Composer
  • installation of geoserver and WebMap Composer to the SEEGrid test server.

Next steps

  • configure SEEGrid test server with relevant sample data for geoserver and creation of map views in WMC

Dependencies

  • sample data - currently have "reports" - still need database tables, XML examples, XML schema and presentation rtesources (eg SVG and HTML outputs desired by the project team)
  • some minor technical setup issues on the server - many thanks to Robert Cheung at CSIRO who has been extremely proficient and helpful smile

NB the domain specialists technical team should not be dependent on SCO for any of this activity.
