[Handle-info] OpenHandle JavaScript API

["Hammond, Tony" <t.hammond@nature.com>]

Hi:

Blogged this to CrossTech:

#####
OpenHandle JavaScript API
http://www.crossref.org/CrossTech/2008/10/openhandle_javascript_api.html

    "I just posted updated versions of the OpenHandle JavaScript Client
Library (v0.2.2) and Utilities (v0.2.2) to the project site. Mainly this
post is just by way of saying that there's now a "cheat sheet" for the API
(see figure above, click for PDF) which will give some idea of scope. The
JavaScript API attempts to reflect the Java Client Library API for Handle
data structures, and has in excess of 100 methods. A change log is
available.

    The new API supports:

    * Single namespace
    * Introspection
    * Unit testing, see here

    Why is this of interest to CrossRef? Well, if DOIs are ever to begin
take advantage of their innate Multiple Resolution capabiities there needs
to be nimbler means of accessing the data items stored with a DOI. A
JavaScript API would allow the data to be manipulated in the browser down by
the user and so enable bespoke services. That, at least, is the idea."

Well the cheat sheet is fun anyway. And what's kind of neat is that the full
API can be accessed with a single method call:

  // in the browser, e.g. with FireBug
  console.log(OpenHandle.Library().showClassMethods());


  // in a JS shell (SpiderMonkey, Rhino)
  js> load('openhandle.js')
  js> print(OpenHandle.Library().showClassMethods())

And the unit testing is proving to be strangely addictive. :)

Cheers,

Tony
