Good talks at DPM workshop

It's nice to see plans and  issues for DPM sites are similar around the world. Here are my musings:

The fact Australia and Taiwan sites see the approximate percentage of dark files after ATLAS RUCIO renamed their site as I have seen in the UK (8-9%) is encouraging to know that the UK is not especially bad; (now just need to work with ATLAS on how to efficiently clean up these files, delete empty directories; and how to reduce dark data creation in the future.) It will be interesting to see if other VO's have a lower or higher percentage of dark data.

Also good to hear that a puppet deployment of DPM (rather than YAIM) is almost complete for usage and now I have a better understanding of the development cycle of the individual components; I am less worried about the move away from a single product release.
