Yahoo releases many API's to enhance Web Services...

I tip my hat to Yahoo. Good job! It makes me shout "Yahoo!"

Yahoo has summed it all up so well, that here is the text from the web site (the content on Yahoo's page will be updated, so visit the link above to view the most recent version).

New! - Yahoo! User Interface and Design Patterns Libraries

Everyone talks about Web 2.0. Talk is cheap. How about some real help? Just in time for Valentine's day we're giving you a delicious candy box of tools and guidelines for building cutting-edge dynamic web sites.

First, there's the Yahoo! User Interface Library. The UI Library is a set of JavaScript components that let you quickly add all kinds of really nifty features to your web site, from dynamic UI elements like drag and drop, tree views, and animation; to underlying functionality like custom events and easy-to-use cross-browser XMLHttpRequest connections. Its a small easy-to-use framework for building AJAX applications. And get this: Its free to use and its open source (BSD license). Better than flowers any day.

Code is cool, but howabout some advice, too. We've also got the Yahoo! Design Patterns Library, where our best visual and interaction designers have gotten together and created a set of patterns and guidelines for design in a Web 2.0 world. Here you'll find ideas on the best ways to implement web site elements, along with pointers to examples and the tools within the Yahoo! UI Library that will let you do it. Today's Pattern Library is just the beginning -- expect this part of the site to grow quite a lot over the coming months.

Our Yahoo! UI folks, in addition to the insane amount of work they did to bring you all these cool tools today, have also started a blog over on yuiblog.com to keep you updated on stuff going on in the Yahoo! UI world and to get your feedback on patterns and tools. Drop over and say hi!

Webjay

Yahoo! welcomes yet another great new company into the fold -- this time into the Yahoo! Music corner of our universe. Webjay, built by one-man wonder Lucas Gonze, is a site that lets you create and play music, audio and video playlists on the web. With Webjay you can create playlists, build them, share them, blog them, search for them, discuss them and of course play them -- in any music or video player. We here at the developer network are doubly excited because webjay has an API and we like nothing better than an API. (OK: we like gummi bears better than a API. But not by much.) The Webjay API enables you to manipulate and access playlists through familiar REST-like requests. Check out the API at http://webjay.org/api/help or down there on the left in the nav bar under "W."

Yahoo! Travel Trip Plan APIs

The Yahoo! Travel Trip Planner lets you create, organize, and browse, and share information about trips you're planning to take or just want to take. Use the new Yahoo! Travel Trip Plan APIs to search for and retrieve trip plan data created by the trip planner. If you've used the Yahoo! Search APIs, our new Travel APIs will look immediately familiar—they've been designed around similar parameters and schema so you can reuse your code. And as with the Yahoo! Search APIs, the Yahoo! Travel APIs also support JSON output with the output=json and callback=function parameters.

JSON Extravaganza

Now with all our Search Web Services and Maps Building Block APIs you can get JSON output in addition to XML. JSON (JavaScript™ Object Notation) is a small, easy to parse, object notation which is growing in popularity as an alternative to XML for data interchange. You can use it in any programming language, although it is especially easy to use in JavaScript. JSON text evaluates directly into JavaScript objects and the elements can be accessed with standard JavaScript methods. Use the output=json and optional callback=function parameters to use JSON with our REST services. See the new JSON documentation for details.

JavaScript Developer Center

In conjunction with the release of JSON support for our REST web services we're also announcing the JavaScript Developer Center, a new section of the Yahoo! Developer Network packed straight up to the rafters with links and code samples and tutorials and HOWTOs for using JavaScript with the Yahoo! Web Services and other APIs. If you're a JavaScript developer, or want to do more with AJAX and web services and Yahoo!, there's enough here to keep you busy for a very long time. You can get to our JavaScript Developer Center any time from the side bar over there on the left.
