Re: Reserving federated database IDs for RHIC

["Craig E. Tull" <cetull@lbl.gov>]

Sounds like a good idea. However, Is 100 really enough for the long term?

100 is clearly enough for "real" federations. However, I can imagine that
software developers will want to be able to conduct tests using several
federations to avoid any dependencies between tests (This is what I do
these days.). Since many people will be doing software development, it
seems possible to exceed 100 FDB IDs rather easily.

This also raises the question of allocations within an experiment/project.

Currently, I use my LBL extension number (ID=7253) for my own little
scratch FDBs. This would be a nice little policy for assigning scratch IDs
to individuals (if the range allowed it) at a particular site. However,
would not work between sites (I'm tempted to call 516-344-7253 and see who
I would get. 8^) ).

I recommend that the Grand Challenge have a dedicated range of IDs as well.
