Re: [equinox-dev] [prov] ECF discovery of artifact and metadata repos


Initially, I'm thinking of setting up a discoverable http server to expose p2 meta-data and artifact repos. I noticed that there is an Equinox application: FileServerApplication (in org.eclipse.equinox.p2.tools plugin). Would it be OK to add discovery to this app (via patches)? Or should I create a new separate DiscoverableFileServerApplication?


Also, would there be any interest in adding a discovery client to the ProvAdminUI? We have a general service discovery view in ECF

http://wiki.eclipse.org/Update_Site_Discovery
http://wiki.eclipse.org/Discovery_of_Remote_Services

but it would be desirable to have a UI with less detail, that only shows meta-data and artifact repos rather than all services...and doesn't show all the details of the service properties as the ECF discovery view does.

Hi Scott, repository locations are simply represented as a URL. Since both metadata and artifact repositories are pluggable via extension point, any valid URL could potentially represent a repository. Currently the one way to find out if a give URL actually represents a repository is by calling loadRepository(URL, ...) on either IMetadataRepositoryManager or IArtifactRepositoryManager. Hope that helps get you started...

In prep for EclipseCon, the ECF team would like to create a demo that
discovers p2 artifact and metadata repos.  ECF has a discovery API [1],
now implemented with both zeroconf/bonjour and SLP providers [2].  We've
recently done an example that discovers update sites on lan [3].

So, my main question is:  for discovering artifact and metadata repos,
what is the necessary meta-meta-data? (data about location/access to
repos).  Is it simply an URL, or is there more to it?  Pointers into p2
code desired...as I need to do that anyway.

Thanks,

Scott
