We are still trying to get a complete end-to-end scenario working. There were several issues that the team needs to address.

  • It is still not clear how the notion of context and navigation will work and what APIs should be used.
    • Sheldon & Marius will work on this and post their conclusion on the wiki
  • There was an issue around how the initial configuration would be bootstrapped.
    • Sheldon mentioned that using report parameters would be a stop gap way to get around this for the demo
    • Marius will take an initial pass at how this will work long term
      • Bugzilla here
  • The CBE Events report, or the code that loads the data needs to be modified to use the data access layer
  • Sheldon has created a statistical report that needs to be integrated
  • We need a pre-canned database that contains the log and statistical data for the demo. This will be a derby db.
  • The Production.XML file needs to be update to have parent->child relationships, not just the child->parent.
  • Need to determine if we need to have a top level “topology” element
  • We need to determine whether we should allow editing of genic/phenic documents inside the SML-IF editor
    • Currently the user is able to modify the content that appears in the identity element, add/remove/modify document aliases, and add/remove genic/phenic documents. We need to determine if we want to allow the user to modify the content of genic/phenic documents inside the SML-IF editor. In a previous discussion Valentina argued that modifying the content of genic/phenic documents in the SML-IF editor is not a valid use case. Her argument was that the signature of an SML-IF document can be void if the content of genic/phenic documents are modified. Since we are already allowing editing of other parts of the document (e.g. aliases), then the user can still void the document signature. This needs to be sorted out in the resource modeling call. Providing an editor with very little editing capabilities doesn't have much use to the community.

Joel walked us through the set of work that he has done around adding a WSDM-based control interface for the agent.

  • This was done using some annotations that add management support
    • NOTE: This adds a dependency on Java 1.5
  • Next step is to incorporate the persistence API
  • We need to work in how we check in the code in CVS
