Thomas Mueller commented on OAK-178:
------------------------------------

I suggest the index metadata should be stored at

    /jcr:system/indexes

> Unlike Jackrabbit 2.x, indexes in the Oak query engine are user defined, that means data is only indexed if there is a matching index. Those indexes are then automatically used for the appropriate queries. The current plan is to define indexes as nodes within a repository. An index is created if an index metadata node is created, and the index is removed if the index metadata node is removed. The index content is automatically updated if the content changes (either synchronously or asynchronously).
> The location and structure of the index metadata needs to be defined and documented.
> Also, to simplify defining and managing indexes, it may make sense to write a utility (helper class) for managing indexes. Internally, this utility uses the regular JCR API and accesses the documented index metadata nodes.
