It was Ivan Frade who said at the right time 26.09.2009 09:55 the
following words:

pimo:Tag is for systems that want to achieve a highlevel integration of<br>
Addressbooks, Calendars, Websites, etc... into a semantic network.<br>
pimo:Tags are then not only tags, but can be also a pimo:Person - that<br>
is, you can use a person's name to tag something but - surprise - it is<br>
also a person</blockquote>
<div><br>
Out of curiosity: so "pimo:Tag" is then a generic "link" between two
resources? <br>
</div>

nope, uppercase always indicates a class. if you can read N3 (afaik you
do):<br>
<br>
claudia:Belfast a pimo:City, pimo:Tag.<br>
<br>
claudia:MeetingInBelfast a pimo:SocialEvent;<br>
pimo:hasTag claudia:Belfast;<br>
pimo:hasLocation claudia:Belfast.<br>
<br>
as you see in this simple example, there is a "transition path" between
dumb tagging and clever semantics - the city can be seen both as a Tag
for the meeting but also as a location. Difference in code is: only the
pimo:hasLocation is authorative enought that the code issues a google
maps plugin to show the location.<br>
<br>
today, we live in a world of dumb tags and this is fine,<br>
above example shows how we can get to semantic web in the next years,
without breaking backward compability.<br>

It sounds like we could replace all properties between concepts
(exclusing inheritance) as tags: "music piece belongs to an album"
could be a Tag, Contact sent an email..." another tag, "Contact has
postal address" another tag....<br>

now clicking on the person will get more...<br>
a pimo:Tag has the semantic meaning of : the tag is a unique string<br>
which is also a Thing out of the real world which can have more
attributes.<br>
</blockquote>
<div><br>
Then it is opening the door to all kind of "custom properties". A
pimo:Tag is like a property between two things that the user can
label... it sounds pretty dangerous.<br>

hm, I think its not.... but I don't understand everything you said....<br>
<br>
please read the section on tagging in the spec and ask again:<br>
