modify discovery service
Hello! I need to modify the reference implementation of discovery service, in order to use a set of keywords as search criteria. The getRemoteAdvertisement method allows user to specify the pair Attr e Value to define the criteria that advertisement must fulfill to satisfy the query. I would like to build up a new discovery service in which users should specify a set of pairs "Attr-Value" instead of a single pair. Is there any known project or any documentation in which this issue has been already faced? Maybe I've should implement a new group service, but I'm confused about it. The programmer's guide 2.5 doesn't tell much about it...
Thanks for any suggestion!
