Machine tags (and microformats)
 |
I'm finding machine (aka triple-) tags both useful and interesting. I think we've only just begun to scratch the surface of their potential.
For books, instead of (or perhaps as well as) the Open Library scheme (openlibrary:id=) I'd like to see, for example:
book:isbn=0711941092
linking to either this Wikipedia service:
en.wikipedia.org/wiki/Special:BookSources/0711941092
(which, in turn, does link to Open Library); or Flickr's own equivalent; or perhaps a choice of target set in user-preferences. There's more choice for the user there, and it's easier to find an ISBN than a book's ID on a specific website.
Where Flickr knows an ISBN, it could also retrieve, from one of many on-line services, the title and author.
All of the above also applies to ISSNs for journals.
Where pictures are geotagged:
geo:lat=-1.56403 geo:lon=53.60913
you could automatically transfer those values to your map, rather than the user having to find the location manually. Conversely, pictures with coordinates in their EXIF data or on the map could be automatically (and perhaps optionally) geotagged.
For the scientific names of living things, like Alcedo atthis tagged as:
taxonomy:binomial=Alcedo_atthis
(Also divinable from taxonomy:genus=Alcedo + taxonomy:binomial=Alcedoatthis )
and even vernacular names tagged as:
taxonomy:vernacular=Common_Kingfisher
you could link to the Wikipedia page; or one of the many online taxonomic resources; or again offer a choice of links.
There are already over 175,000 "taxonomy:" tags on Flickr, according to husk.org/code/machine-tag-browser.html#tag=taxonomy. They're already been used by the exciting Encyclopedia of Life project's Flickr pages. More about Taxonomic Machine tags on my blog.
You could discretely mark up some machine tags with microformats:
[a href="..."]taxonomy:binomial=alcedo_atthis[/a]
becomes:
[a class="biota" href="..."]taxonomy:binomial=[span class="binominal"]alcedo_atthis[/span][/a]
and:
[a href="..."]geo:lat=53.60913[/a>
a href="..."]geo:lon=1.56403[/a]
becomes:
[span class="geo"]
[a href="..."]geo:lat=[span class="latitude"]53.60913[/span][/a]
[a href="..."]geo:lon=[span class="longitude"]1.56403[/span][/a]
[/span]
I'd be happy to expand on these ideas further (I'm the author of the "species" microformat, and have helped Frankie Roberto with his Open Plaques website), either here or in private e-mail with Flickr staff. You know where to find me.

looks forward to more robot squirrels and more referencing/linking/markup of special machine tags.
Another one, that might be a "happy compromise" between the rules about commercial/non-commercial use of your flickr stream.
Let all the Etsy kids use a machine tag to associate photos of their creations to the item listing on Etsy? Many etsy users upload to flickr, but have to be careful not to do too much overt marketing of their crafts.

re: geo:lat and geo:lon. There's already a tool to convert machine tags to location metadata. I've seen people ask for tools to go the other way, but I can't see the point: Flickr has lots of methods that do Clever Things to turn raw lat/lon pairs into places of various levels and to cluster the data. Compared to that a list of geo: pairs seems pretty useless
However, if you really cared, looping over photos with geodata and setting tags via the API would be pretty straightforward.

Yeah the lat/lon was the least interesting I thought, but also the one that flickr already does the most magic with in other ways.
