ISSUE-34 (Subslices): Clarify or drop qb:subslice ? [Data Cube Vocabulary]

http://www.w3.org/2011/gld/track/issues/34

Raised by: Dave Reynolds
On product: Data Cube Vocabulary

The Data Cube slice mechanism allows hierarchical organization of slices though the use of qb:subSlice.

However, it is not possible to distinguish between different levels of sub-slice when defining attachment levels, which in terms makes abbreviated formats for such cubes under-defined.

Possibilities include:

(1) Deprecate qb:subSlice (der has not seen it use in practice, despite originally arguing for its inclusion in the spec).

(2) Retain it and add machinery or constraints on its use with abbreviated formats.

This relates to ISSUE-33
