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

[Scott Lewis <slewis@xxxxxxxxxxxxx>]

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.
