id

I made a small web application, IDAvailability that checks how available the entered ID is in the world.

Web services

I added only 8 web services at the begenning. However, web service information is stored in wedata, a wiki-like data store that everyone can edit, everybody can add web services to it (for now, 28 web services has been added). Database is here.

You can add a web service from Create New Item, and enter following information.

• name : name of web service (any)
• urlToCheck : URL embedded #{ID} variable (like http://nantokakanto.ka/user/#{ID})
• condition : a XPath expression to check whether the ID is used when the server response is HTTP 200 , not ”404 Not Found” while accessing urlToCheck. (for example, see flickr)

Code

• Coderepos/websites/idavailability
• revised BSD

ToDo

• Move check functions to client-side (retrieving HTML via Ajax, examining XPath…)
• Better looks

Try and enjoy it, also add your favorite web service missing.
