RE: Additions to BP glossary


I am happy with that dimension definition providing it is clearly restricted to geometry or similar.

I think the that the wider use of dimension, as in the w3C RDF QB definition is valid, as in statistics and spreadsheets - e.g. dimension of: countries in UN; butterfly species in Europe; list of variables in this NetCDF dataset where the other dimensions are x/y/z/t; calendar based timeline; etc. 

This use of 'dimension' is also used in the OGC Web Map Service (WMS) standard for the display of maps and their layers.

Rob Atkinson in the QB4ST work is trying to address this issue.

Subject: Additions to BP glossary


As part of my tasks on the revision of BP8 (ACTION-249), I have been reviewing the BP doc as a whole, in particular wrt the notions used in BP8.

I realised that the notion of "dimension" (and its variants - e.g., "dimensional", dimensionality") is never explicitly defined, despite it is widely used across the BP doc. In most cases, it refers to the dimensions of a geometry, but in few cases it is used also for other contexts (e.g., the dimensions of statistical data).

I would suggest we add an entry to the glossary - at least about the notion of "dimension (geometry)" - we can point to from the relevant sections. There we could include also examples of dimensions, with the notation we are already using in different places of the BP doc - 0D (point), 1D (line), etc.

If this makes sense to you, I wonder whether you have a definition to suggest. I quickly checked on the ISO/TC211 terms, and this is the relevant entry:
