Tomek Rękawek commented on SLING-848:
-------------------------------------
Actually, it adds a new marker interface to the ResourceProvider. I think it's
compliant with the previous discussion:
{quote}
The sling resource resolver will extract uri parameters from the uri and pass
them to the resource providers in an additional parameter. Currently the
resource providers just get a path; we will extend this to be a path and a map
of all uri parameters.
The map of uri parameters will later on also end up in the resource meta data.

In the first version I modified the ResourceProvider interface, but Bertrand
pointed out that it would be incompatible with existing ResourceProviders.
That's why there is the new ParametrizableResourceProvider.
> Support getting versioned resources by using uri path parameters

> Key: SLING-848
> URL: https://issues.apache.org/jira/browse/SLING-848
> Project: Sling
> Issue Type: New Feature
> Components: JCR
> Affects Versions: JCR Resource 2.0.2
> Reporter: Carsten Ziegeler
> Assignee: Bertrand Delacretaz
>
> Getting versioned content should be support thorough uri path parameters,
> like /something/hello;v=1.1
> For jcr based resources the value of the version should either point to a
> version name or label.
> In order to not change our existing apis, we introduce a new utility method
> which removes all uri path parameters
> and returns a map of these. Every resource provider could use this utility
> method and then decide to act on these
> parameters.
> If a requested version does not exists, a 404 is returned.
> If the requested node does not directly point to a versionable node, the
> algorithm checks the parent hierarchy until a versionable node is found, and
> tries to get the version of this node and then goes down the path again. If
> the versionable node does not have the requested version or the child, a 404
> is returned.
