Just as an example, here's a talk I gave to an SRM workshop in November
2007:
http://indico.cern.ch/materialDisplay.py?contribId=8&sessionId=1&materia
lId=slides&confId=21405
Note the comment about glue 1.2 SAs at the bottom of slide 15.
(Incidentally, the publication scheme we have now has moved on from
what's described there - in particular we do now publish an SA per
space, the technical objections turned out not to be so serious.)
Overall we've had some major migrations in the data management area
over the last few years - edg-rm to lcg-utils, RLS to LFC, classic SE to
srm v1 to srm v2 plus space tokens, and glue 1.1 to 1.2 to 1.3 to 1.3
plus installed capacity publishing. Personally I think it's fairly
impressive that we've done all of that without breaking
backward-compatibility, and to some extent without people even noticing,
as shown by this discussion. Would a huge disruptive change have been
better?!
