[Yum-devel] Q: New <origin> attribute in repomd.xml?

[Michael Andres]

Hi.

We (@opensuse) want some easy way to check whether a some rpmmd repository is 
already used on a system. Detection should work even if the repo is available
via different URIs (e.g. http and DVD, or two different mirrors).

The idea is to introduce a new tag in repomd.xml:

       <repomd xmlns="http://linux.duke.edu/metadata/repo"
 +             xmlns:suse="http://opensuse.org/metadata/repo">

 +     <suse:origin>obs://build.opensuse.org/zypp:Head</suse:origin>
       <revision>1267717198</revision>
       <data type="primary">
       ...

<origin> should be some optional string provided by the creator of the 
repository. If two repomd.xml contain the same string then they are expected 
to contain metadata for the same repository (maybe in different revisions).

This would enable you to detect duplicate repositories or test for the 
presence of a specific respository on a system (provided you know the 
creators naming schema). 


The question came up whether you'd find such a tag usefull as well?
If so and we could agree on a common name, we'd use this instead of 
<suse:origin>.
