Hi,
The thesaurus of objects, as we are using it, it clarifies somehow use and function: in the example above:
Categoria: Indumentària - Component d'indumentària- Element de fixació
The structure that leads you to "botó" gives you information about "us i funció":
it says that is an "element de fixació" so is used to fix things, that is a "component d'indumentaria" so it says is a part of dress, and use it for dressing. So, as I see it, it is not the final item "botó" that is of intesest here, but the threat that leds you to this kind of information.
To specify this questions:
Context
Where
Who
When
Are connected to tematic tesaurus that it is not so specific about the information we need as the structure of the tesaurus of object.
So I'm not sure how to proceed, but it seems not efficient to "copy" the threat (structured field) to a text field (not structured).
Thank you
