Thank you very much for your help Richard.
I will start another thread about my "distribution" problem to set a
context and hopefully get some insights about other possible approaches
to the problem.
Regards and thanks again.

Is that API available as a bundle to download?
The Felix OBR bundle provides that API. The OSGi API is also
optionally provided, but you have to download that OSGi OBR API as a
separate bundle. (i.e., you only need the Felix OBR bundle installed
to use the Felix OBR API, but you need the Felix OBR bundle and the
OSGi OBR API bundle installed to use the OSGi OBR API with the Felix
OBR implementation)
I see in the Felix svn trunk that the RepositoryAdmin has a "new"
method:
> Resource[] discoverResources(Requirement[] requirements);
Is that what you mean?
Yes.
Also, I need to "ask" for the resource (bundle) in other server, so I
need to transmit the "requirement" through the network. Is there a
way to do this (e.g. create a requirement from a string) using only
the exported API or should I use the specific implementation?
Not sure what you mean. The OBR bundle and/or spec has nothing to do
with distribution, so you are on your own there. However, yes, it
should be fairly easy to serialize a requirement since they are
already read from an XML file to begin with.

The original proposed OSGi OBR API didn't provide a way to do this
from the RepositoryAdmin. You need to use the Felix OBR API, which
exposes such functionality on its RepositoryAdmin.

Hi everybody,
I'm doing some experimentation with OBR (API) and I don't know how
to find a missing requirement with it.
That is, if I have a filter expression (as used in a <resource>'s
<require> description in a repository xml file), is there a way to
query the OBR service (by means of the repositoryAdmin, I guess)
for the bundles that satisfy that requirement?
For example,
I have the filter: "(&(package=org.foo.somepackage)(version>=1.3.0))"
Then I would like to query for some bundle that exports the package
"org.foo.somepackage" with a version >= 1.3.0.
From the documentation in the RepositoryAdmin class (revision 1.3):
"Checking the capabilities of the filters is not possible because
that requires a new construct in the filter."
I guess it can't be done. But maybe I'm missing something.
Thanks in advance for any insight about this.
