I've just discovered the tagging feature of RHQ. I've been looking for it in JON but can't find it. Has it not been ported or have I missed something? I'm using JON 3.2.0.GA.
Tagging together with dynagroups by tags and search queries by tags and maybe even bundle deployments by tags would just what I'm looking for right now. (I have a rather big setup here with very specific use-cases that would be solved very elegant with tags.
