Hi,
as others may be interested in this discussion, I am also including xesam
(= the ontology developers list)
I was a bit slow to answer, sorry.
Tomás - what are you programming? do you have a url or a blogpost about
your work?
nao:Tag is for systems that just use NAO/NIE and are fine with
no-brainer solutions.
a nao:Tag has the semantic meaning of : the tag is a string. its unique.
pimo:Tag is for systems that want to achieve a highlevel integration of
Addressbooks, Calendars, Websites, etc... into a semantic network.
pimo:Tags are then not only tags, but can be also a pimo:Person - that
is, you can use a person's name to tag something but - surprise - it is
also a person.
now clicking on the person will get more...
a pimo:Tag has the semantic meaning of : the tag is a unique string
which is also a Thing out of the real world which can have more attributes.
I also documented this here in the FAQ
https://sourceforge.net/apps/trac/oscaf/wiki/PIMO/FAQ#Whatisthedifferencebetweennao:Tagandpimo:Tag

> About pimo:Tag description:
> "Tags in the context of PIMO. A marker class for Things that are used
> to categorize documents (or other things). Tags must be a kind of
> Thing and must have a unique label. Documents should not be Tags by
> default."
>
> About nao:Tag description:
> "This class is useful for modelling conventional tagging practices.
> The user can tag resources in conventional ways, automatically
> creating an instance of this tag, which is then related to the
> annotated resource via the nao:hasTag property. For more on tagging as
> annotation see Section 2.3.". I've read this section and the
> explanation is very convincing.

> Thanks in advance.
> Kind regards
