Aaron and I have made a few changes to sail data emf recently. We've basically been adding new properties to the learner data bundle.
Because this is a change to the learner data bundle, any code that processes that bundle should be checked with the new bundle format. If the code ignores xml elements and attributes it doesn't know about, it should not be affected. I think the TELS portal is using EMF to load in the bundle so it can be used by the teacher report tool. That saildataemf.jar file the portal is using will need to be updated so it can handle these new bundles. These new properties help with the following issues: - computer date is not set correctly - bundles are uploaded out of chronological order, but they should be delievered back in chronological order. - associating a bundle with a particular launching session. - recording the portal delivered session properties, so things like the wise session properties are now recorded. This makes it possible for a reporting tool to be coded which could use the properties in the bundle to display the WISE discussion used by the activity. One side effect of these changes is that learner data files are now stored locally in a different place. The old location was: [home folder]/SailUserData the new location is: [home folder]/SailUserData/v368 The 'v' stands for version. The '368' is the current svn revision of the saildataemf.ecore file. That is basically the schema file for the bunlde's xml. If we revise the ecore file to add new properties, then the folder name will change. This folder naming design is for backward and forward compatibility. We can now completely change the format of the bundle and it will not cause any old code to fail.
