元々は twittermap というサイトで使うために提案された記述方法らしい。







名古屋城についた L:愛知県名古屋市中区本丸1-1
L:愛知県名古屋市中区本丸1-1: 名古屋城についた


* L:
      o Used to define a location
      o May be followed by a trailing colon to indicate the end of the location (Example 4)
      o Example: Good place to visit L: Place Georges Pompidou, Paris, France
      o Example2: Good place to visit L: Place Georges Pompidou, Paris, 75004
      o Example3: Good place to visit L:48.860500,2.352260
      o Example4: L:San Francisco: is a nice place. 
      o Text Syntax: L:<Addres, city or town, region> or L:<Address, city or town, postal code> at the end of  a tweet
            + info  Twittervision API, Google maps
      o Geo Syntax: L:<lat,long>
            + info: (Section 3.4.2 of RFC2426)
      o Tools: Twittervision, Twittervision API, twibble, a location aware twitter client and API, location filter pipe

How can I easily change my location on the map?
Simply send a Twitter update that includes 'L:' followed by your location. Examples: 'Going to the office. L:3000 6th Ave, New York', 'L:Rouen, France', 'L:Disneyland', 'L:Las Vegas, NV', 'L:EWR', 'L:90210', 'L:30.010,-90.007'. There is no need to specify lat:, long: when giving coordinates.
Can I update between home, work, the bar, school, etc?
Yep! Now you can define location macros which you can use to quickly update your position.

  * L:home=517 Spruce Ln, Lenexa, KS 60502
  * L:work=300 Alameda Parkway, San Jose, CA 92012
  * L:sarahs=Rue Ducasse 75, Paris, France
  * L:tim's=Auguststrasse 5, Berlin, Germany
  * L:parents=Burnside Cr, Melbourne
  * L:owl bar=1000 Charles St, Baltimore, MD 20507
  * L:school=3700 University Blvd, Berkeley, CA 95010

Once these are setup you can move from place simply by including 'L:home' or 'L:work' in your updates! Now it's easier than ever to update your position! Here are some more examples of valid and invalid locations.

Valid Location Setting Examples
The following strings are examples of how you can correctly set your location and use personal location definitions on Twittervision and Twittermap using Twitter updates. Personal locations can be defined using the format L:place=address, where place can be any easy-to-remember word.

going to l:home, then to bed
l:arvada, co for now
l:work, for now
l: bar=500 nyals st, chicago
l:work=123 main st, annapolis, md
l: school=320 smith st, columbus, ga: ok?
will it find me in l:nyc?
l:200 Broad St, Philadelphia, PA
going to the l:office
back l:home for some rest, finally
just arriving at l:work, hoping it won't be a crazy day
never to early to go to the l:bar! meet you there
sigh -- l:124 main st, 80303: but wishing I was at home
l:304 Samuels Rd, Newton, WV: through thursday
no time right now l: fiske st, toronto: party tonight anyone?
now going to L:school, wich stinks
You do not have to define personal locations (say for a short trip), but can instead update your location to any geocodable location using the format L:address. You can also separate location-setting from the rest of your message with an additional comment.

For you tech types, the valid supported syntaxes are:

L:place=address[:] store a personal location
L:place[:] set a stored personal location as current location
L:address[:] set an arbitrary location as current location

  * place may be one or more words; one word is preferred.
  * address may be any geocodable location. Use Twittermap search to search on a location before specifying it in an L: tag if you are not sure it is valid.
  * L: is case insensitive, so you can use l: too

・さて、緯度経度が分かったところで、いよいよTwittermapに登録だ。といってもTwitterでいつものように発言するだけ。 TwittermapはみんなのTwitterの中から、L:と書かれた情報に反応するように出来てるらしい。homeという名前で家の場所を登録するには朕の場合なら、
Updating my location. L:home=35.685374,139.753097
魔法の呪文って言うのはまたしても多分嘘なんだけど、なんか英文と一緒に書けば反応するみたいだね。登録時は日本語は書いちゃダメみたい。僕は、 twittermapでうまくやってる人を探して、その人の登録の発言をコピペして登録してみたら、うまくいったので、毎回この人の発言をコピペしてるというわけです。ありがとう○○○○○○。
