             Summary: Add ResourceCollection to SLING
                 Key: SLING-2853
                 URL: https://issues.apache.org/jira/browse/SLING-2853
             Project: Sling
          Issue Type: New Feature
          Components: API
    Affects Versions: API 2.0.2
            Reporter: Amit Gupta
            Priority: Minor


Creating a collection of resources has been a use case for a while and there has been no inherent support in SLING for the same.

This proposal is to add a ResourceCollection interface and implementation that allows creation of collection of resources. 
Collection is a simple list of members, where each member contains path of resource it refers to. In future, we might need to store additional information with the member, hence following structure is proposed

{code}
N: resourceCollection (nt:unstructured)
        + P: sling:resourceType
        + N : members (nt:unstructured)
            + N: member_res1  > nt:unstructured
                + P: path > string, reference to actual resource
            + N: member_res2  > nt:unstructured
                + P: path > string, reference to actual resource
{code}
