Present: Mattias, Balazs, Aleksandr, David, Jon, Anders (last minute), Oxana
= News
Balazs is looking at why GLUE2 of ARC-CE is not visible in top-BDII: GLUE2 spec does not specify the actual tree structure, so everybody defined trees differently, and ARC's is not compatible with top/site-BDII. Converging is not trivial, but it has to be done. Would trigger a major release for sure.
A student in Lithuania would do a master project related to ARC.
Back-ends meeting in Copenhagen tomorrow, Skype can be used for remote paricipation.
ARC-CE workshop will be held in Barcelona during first week of March.

= Release status
Many important fixes are in, including GGUS #116068. Watchdog is yet to be fixed (but no need to wait), and Davis is reporting one more. So the release process can start some time next week.
LHCb uses ARC from their own sources (via CERN afs).
= S3 DMC
Brings in a new dependency (libs3), which is easier to be bundled with ARC, but in turn it needs licurl which so far was not a dependency. Mattias wonders whether it won't be better to package it separately, as bundling is not really welcomed unless it is something very obscure. So far it looks sufficiently obscure. However, there is a Debian package called libs3 which seems to be the same thing. We can package it for Fedora. Mattias and Jon will look into it.
Another question whether it should be a separate package - indeed, most people won't need it, so the best is to package it separately.
