We propose to make the following changes to the SD spec - attribute names to start with a capital letter This has already been discussed and agreed - add attribute "InformationServiceUrl" containing a ref to the source of the information We want this so that it is possible to determine where the information has come from. It will not be possible to use this attribute for selection - use the URL in the discoverer constructor instead. Note that it is "InformationServiceUrl" rather than "InformationServiceURL" - add attribute "ImplementationVersion" - taken from the corresponding GLUE field - add attribute "InterfaceVersion" - taken from the corresponding GLUE field - add multi-valued attribute "Capability" to match the GLUE-2 capability which in turn uses the OGSA defined set of values This was discussed within a small group at LSU F2F This will be more useful than the current "Type" as service types tend to be peculiar to one grid. The description of type will simply say: "type of service. This API does not restrict values of the service type - it might be a DNS name, a URN or any other string." and table 1 will be deleted.
