No no, it was about the meaning of the tag, and not the tag itself :)

No, at least, I don't think so based on what Alex wrote on MOAT's web site.

It is why each meaning is linked to a person that linked the tag with 
its meaning. If you check the cardinality of a Meaning, then you will 
notice that there have to be a "maker".


Semi-supervised system because it seems that a MOAT server send you a 
list of possible meaning for each of your tag, then you choose the ones 
you want to link a meaning with a tag.

Yeah, totally agree. Terminology is always the problem, and reaching a 
consensus is the worse part of any such projects :)

Not the tag that has a meaningURI, but a "meaning" :)

But the real question is there: does a meaning is a concept only, or 
anything? It is the question we have to investigate with pros and cons :)

Currently yes it does. It is one of the problem I have with it.

It could at some level, explicitly by not authorizing anything to be a 
meaning. So this could helps reasoners a bit.

No, it is not :)

Possibly. But in that case, you can query the system to get a list of 
tags related to a specific meaning. This is where the whole thing is 
powerful! :)

There is one more step though (linking a tag with meaning(s)

But there is no meaning with a seeAlso. Possibly if we think about 
browsing, but not really if we think about querying the dataset.

Sure, but it doesn't mean that we shouldn't take some time to get things 
done properly :)



Take care,
