Dear Valeria,

In our discussion on pruning Agrovoc you wrote:

"We can hopefully provide a more straightforward solution in the next months, as we are going to implement a similar setup in our AgriFeeds portal. We will use the FAO Topics instead of the ASC, but the approach is the same: we will use two taxonomies for the FAO Topics and for AGROVOC and we will link them based on the AGROVOC mapping. This will help us have a simpler navigation using the FAO Topics but still use the power of the AgrovocField automatic indexing.

Another idea could be that of implementing the mapping directly into the AgrovocField module, so that every time an Agrovoc term is selected, the corresponding mapped terms from mapped classifications are imported into other local taxonomies and linked to the Agrovoc term. Thsi would require some configuration functionalities to allow the administrator to enable only specific mappings."

As I am targeting a user group that has an interest in agriculture, trade and social issues, I will anyhow have to work with a more diverse set of vocabularies than Agros-Agrovoc only. Many vocabs are however not of-the-shelf. ISO 9000 related terms are copyright protected. The ILO vocabulary and ILO Thesaurus don't seem to be built in the same structure and logic as the Agrovoc.

I doubt whether it is attractive for me to start developing linked vocabularies via VocBench. Lots of work, and the interested target group might be too small.

An alternative approach towards linke data may be to work via entity references from within my own site: I import a set of controlled vocabularies locally to my site, and use these for tagging of content. When I tag one document with terms from two or more vocabs, on the fly I thus create a linkage between the vocabs.

What do you think?
