Carsten Ziegeler commented on SLING-9662:
-----------------------------------------
[~henzlerg] What is the idea to integrate the existing mapping functionality?
Will that be wrapped by a ResourceToUriMapper that is always there?
I think one of todays problems (that we also see in the issues mentioned by
Robert) is that we tied resolve/map to a resource resolver. In hindsight it
would have been better to have resolve() as a separate operation which is run
as a first step, even before authentication. I'm wondering if this SPI can
provide a path to such a change?

> Key: SLING-9662
> URL: https://issues.apache.org/jira/browse/SLING-9662
> Project: Sling
> Issue Type: New Feature
> Components: API
> Reporter: Georg Henzler
> Assignee: Georg Henzler
> Priority: Major
>
> Introduce a simple SPI that allows to contribute to the resource resolver's
> map() and resolve() methods:
> *ResourceUri:*
> General purpose class to represent a ResourceUri (like e.g. a link in an html
> <a> tag). Immutable itself but adjustable using the builder pattern. Part of
> the Sling API and can be used anywhere to simplify handling/modification of
> Sling ResourceUri. Implements RequestPathInfo. ResourceUri can be created
> easily from a String, a Request, a Resource, a URI or a RequestPathInfo.
> *ResourceToUriMapper:*
> SPI interface to be implemented as OSGi Service. All registered services
> build a conceptual chain sorted by service ranking. The resource link is
> passed through the chain while any ResourceToUriMapper chain member may or
> may not make adjustments to the resource link.
> rr.resolve() passes through the chain starting at the ResourceToUriMapper
> with the <strong>highest</strong> service ranking and rr.map() passes through
> the chain starting at the ResourceToUriMapper with the
> <strong>lowest</strong> service ranking
