OGSA-EMS Information Services – Wednesday 6:00-6:45
The OGSA-EMS architecture was sketched out over three years ago. Since
then the lowest level components, e.g., OGSA-BES, OGSA-ByteIO, RNS, have been
developed, and higher level components, e.g., RSS, are under development. At
this point it is time to tackle the OGSA “information services”
problem. BES containers and other services have “resource properties”,
“metadata”, “attributes”, or whatever you want to call
them. What is needed is a standard place and mechanism to query over the
attribute space. For example, services such as MDS in Globus, Collections in
Legion, etc. In this session we will begin the discussion of how to attack this
problem. We invite others, e.g., Info-D group members, to attend.
