In reading the threads I didn't get the part about including a URL in an hCard to point to another hCard. That is helpful. OTOH I think (as you imply) this discussion might be attempting to use a pickaxe to resolve a problem that requires a bulldozer. Or said another way, trying to resolve a problem whose proper solution lies in a different domain. I've actually recently been thinking about a related question. i.e. what is a person's canonical URL? Google Roy T. Fielding, Bill Gates, Linus Torvalds, or even John Allsopp or Mike Schinkel and tell me which URL is the canonical URL? I've been planning to blog about this for weeks. Do you, or anyone, have a proposed solution to this dillema? Basically the problem is simplified as What URL identifies a person, and more importantly, how does someone who doesn't know that person or can't reach that person to ask be able to find it? And, being an advocate for Well Designed URLs, I do not think the right solution is to simply tag a random and undiscoverable and unmemorizable UID onto the end of a URL. But I'd have to understand the problem domain and use-cases to be better able to make an alternate proposal. -- -Mike Schinkel http://www.mikeschinkel.com/blogs/ http://www.welldesignedurls.org http://atlanta-web.org - http://t.oolicio.us It never ceases to amaze how many people will proactively debate away attempts to improve the web... ___ microformats-discuss mailing list microformats-discuss@microformats.org http://microformats.org/mailman/listinfo/microformats-discuss

But I'd have to understand the problem domain and use-cases to be better able to make an alternate proposal. I think you're still a bit confused about what was suggested. Every URL is already a potential UID, so there's no need to add anything onto the end. URLs are unique, and some of them (e.g. http:// theryanking.com/blog/contact/#vcard) identify people. That's all a UID needs to be: unique and identifying. Many UIDs happen to be random strings of numbers and/or letters, but that's not at all a requirement for UIDs. So the proposal was just to add the UID class name to the URL class name, e.g. a class=url uid href=http:// theryanking.com/blog/contact/#vcardRyan King/a, not to add anything to the actual URL.

I think that makes a huge amount of sense. Determining authoritativeness is hard, leave it to another initiative and get almost everything else needed w/o it.

Hi, Ryan
Thanks for summarising. It was getting confusing skipping around all
those threads
I want to address your points out of order, if I may. Firstly, just to
check that I have understood your proposal correctly
Also, the algorithm for finding the most authoritative hCard:
1. if no uid or uid == the uid from the previous iteration/recursion
= you're done
2. if url == uid and there's an hCard at that url, recurse with the
new hCard
To provide examples of my understanding of your proposal:
various hCards for Chris Messina (thanks for having so many hCards,
Chris!) at places such as ClaimID, blogrolls, conference sites etc
would read:
ClaimID:
a class=url uid fn href=http://factoryjoe.com/blog/hcard;Chris
Messina/a
or blog link to Some Conference:
a class=url uid fn
href=http://someconference.com/speakers/chrismessina;Chris
Messina/a
or link from Some Conference:
a class=url uid fn href=http://factoryjoe.com/blog/hcard;Chris
Messina/a
At each of these URLs it finds another hCard that leads on again, thus
identifying a series of related hCards. All of which are tied, by
virtue of the UID, to the value of the element (in this case, 'Chris
Messina')
Eventually, our parser ends up at factoryjoe.com/blog/hcard and finds
an hCard containing:
a class=url uid fn href=http://factoryjoe.com/blog/hcard;Chris
Messina/a
or
a class=url fn href=http://factoryjoe.com/blog/hcard;Chris
Messina/a
The self-referential nature of this link indicates that it is the
'authoritative' hCard.
Have I understood you correctly, Ryan?
I believe so.
I'd propose that the UID is still required at the final hCard, to
explicitly confirming that *this* URL is the definitive one for the
object of this hCard.
Or is an explicit reference superfluous given the implicit
confirmation of the self-referential URL?
You actually bring up a good point that I hadn't thought of yet.
I don't think we need a UID at the terminal hCard in order to
conclude that the hCards represent the same person/organization (or,
at least, their publishers think so).
However, the addition of UID at the terminal hCard may allow us to
conclude that it is authoritative.
My proposal is that we use UID+URL to hint that there's an hCard on
the other end of that URL which represents the same entity. Also,
multiple hCards with the same UID may be considered as representing
the same entity.
To move on, I get the feeling I'm missing something here. Your
proposal seems to me to suggest that we add UID to all URLs to that
indicate the presence of a related hCard (of another hCard which has
the same subject - either person or organisation)
I'd suggest that UID is initially unnecessary. FN+URL could provide
the same understanding - eg a unique combination within a hCard,
defining the subject of the hCard and providing a pointer to further
information
This is too brittle and lacks explicit semantics. I've actually build
a tool that tried to do cluster of hCards by FN+URL (based on data
from our search engine [http://kitchen.technorati.com/search/]), but
found a large number of false negatives. For example, if you linked
to by blog the link form the mf.org blog to my blog wouldn't work,
because the FN's are different ('Ryan' vs. 'Ryan King').

(a) Start Source Page (e.g. http://microformats.org/) address class=author vcard a class=url fn uid href=http://theryanking.com;Ryan/a /address The url uid indicates that the consumer should dereference to http://theryanking.com; (Rule #2) (b) URL Page (http://theryanking.com): Ryan changes: a href=http://theryanking.com/blog/contact/; title=contactcontact/a/li To div class=vcard Contact a class=url fn uid href=http://theryanking.com/contact/#vcard;Ryan King/a /div The url uid indicates that the consumer should dereference to http://theryanking.com/contact/#vcard; (Rule #2). Note: - we have to use a heuristic to join Step (a) (b). I don't think this is avoidable (c) Authorative URL Page (http://theryanking.com/blog/contact/#vcard): div class=vcard id=vcard a class=url fn uid href=http://theryanking.com;Ryan King/a ... more stuff ... /div Rule #1 stops iteration (uid=http://theryanking.com, which is the uid from step (b)). --- This works pretty good. Two potential changes. Rule 1. if no uid or uid == the uid from _a_ previous iteration/recursion = you're done change _the_ - _a_: no need to go around in circles Rule 0. if this is the first hCard you've seen, and there is a url but no uid, the consumer may dereference once + works with what's out there - asking consumers to do potentially unnecessary work Regards, etc... -- David Janes Founder, BlogMatrix http://www.blogmatrix.com http://blogmatrix.blogmatrix.com ___ microformats-discuss mailing list microformats-discuss@microformats.org http://microformats.org/mailman/listinfo/microformats-discuss
