Hello,

Following the moving of action

> "guus to check with veronique on the terms being outside the iso 
> standard [recorded in 
> http://www.w3.org/2007/01/22-swd-minutes.html#action07] "

from Guus to me, here are the result of my discuussion with Véronique:


GTAA thesaurus (cf. http://www.w3.org/2006/07/SWD/wiki/EucGtaaBrowser) 
contains two main non-standard features.

First are *categories*. These are classes that enable to gather concepts 
independantly from the way they are arranged in the thesaurus (standard) 
hierarchical structure. For example, you have a 'Philosophy' category, 
which comes with a certain number of subdivisions, and gathers concepts 
from different part of the thesaurus.

Second are *inter-facet associative links*. GTAA comes in the form of 6 
different facets (Keywords, Locations, Person Names, 
Organization-Group-Other Names, Maker Names and Genres) that divide the 
thesaurus into semantically coherent lists of entities (and different 
from the aforementioned categories). Inside each of these facets, there 
are traditional broader and related links. There are also associative 
links between concepts from different facets. For example, the name of a 
Queen (Person Names facet) can be connected with the subject 'Queens' 
(Keywords) and the country that she rules (Location). These were the 
links mentioned at 
http://www.w3.org/2007/01/22-swd-minutes.html#action07. Formally, there 
are not in the ISO 2788 standard, but this might be actually due to the 
fact that this standard does not anticipate the introduction of such 
explicit facets. From a semantic point of view, nothing indeed really 
distinguishes the inter-facet link from a traditional associative link.

Cheers,

Antoine
