Alive and Kicking...
We moved much of the functionality out into libraries to allow people to pull in only what they need. Virgil really only contains the rudimentary javascript UI. Since we broke the project out, we haven't had much cause to update the UI or the REST layer. We've focused primarily on the trigger and indexing modules.
Here are links to the other sub-modules:
We're using the modules internally for our core data processing platform though, so definitely let us know if you have any issues or ideas for enhancements.
If you are looking to integrate with SOLR, we thought to leverage our trigger framework to index data w/ SOLR. You can see the proof of concept code here:
