R
-
GMA and OGSA


R
-
GMA is conceptually close to OGSA


OGSA


replaces resources with services


MDS was for locating resources


OGSA has an index for locating services


MDS does not fit naturally though it will no doubt be kept
some time for backwards compatibility


R
-
GMA might (eventually) use OGSA index to provide the
functionality needed for the Schema/Registry


In the short term the R
-
GMA Registry and Schema will
instead be OGSA services


We plan to be quick off the mark with this work

TB2


For TB2 we plan that the main info service
will be R
-
GMA with MDS as a fall back
solution if we can’t get everything ready on
time.


“Being ready” will involve a lot of testing

network monitoring)


March (1.2)
