A few discussions have already occurred amongst community members and a release code-name Komodo (a type of lizard akin to Teiid, the whip-tail lizard) was adopted to identify the next-generation Teiid Designer for the time being.
Options
for incorporating elements of Teiid's new direction could be
accomplished through drastically modifying/removing Designer's current
underlying EMF framework and developing anew from a fresh user
perspective. In addition there may be benefits to creating a tighter
coupling between Komodo and Teiid runtime, as well as incorporating
other JBoss technologies/projects like ModeShape and SRAMP work being done in Overlord.
A summary of the discussions that have taken place and links to applicable JIRAs are available via wiki at:
