Agile in Practice: What Is Actually Going On Out There?

To define and describe a web-service API, many developers would use WSDL. Although WSDL is meant to be extensible to any protocol and message format, most people use it for HTTP GET/POST and SOAP, when writing to WS-* standards. On the other hand, developers writing a REST API using XML over HTTP typically don't use WSDL, or any other standardized definition/description of the API. There will usually be some kind of human-readable documentation, but that's as far as it goes.
Not everyone is convinced that we need to describe and define REST-ful APIs, but there are those who believe it's useful. Tim Bray suggests that it's what we need to allow users to consume an XML/HTTP API in a few lines of code. It's certainly true that machine-readable descriptions of web APIs can allow the generation of a language-specific library. Service Quality and Validation eKit

Many companies use XML and HTTP with no WSDL. Why bother? Thanks. http://www.1qcc.com
An early success for use of XML within BT was in the exposure of existing mainframe services using SOAP/XML messages described in WSDL. These existing services typically consist of structured text messages which could be exchanged over a variety of transports including raw TCP/IP sockets, JMS and IBM MQSeries, however most systems accessed these services via a mid-tier using a client/server technology such as DCE and later CORBA.Business-Internet
I understand the benefits of defining a standard, but it does not always mean that a standard will become widely adopted, instead, some de-facto standards can be very popular and widely accepted and implemented, for example, TCP/IP. Our goji berries website uses XML over HTTP without WSDL, as it is simple to declare the services, and is simple for users to call the services.
Andrew, thanks for the quick note. I've been working on a project to add some more utility to the concert and festival listings at http://www.websortings.com. Basic webpage listings for festivals aren't very good by themselves without date and location data for the actual event. I had done some research, and found some graduate research http://ils.unc.edu/MSpapers/2830.pdf done by Michael Graves at the University of North Carolina. He did a good job of defining the data schema, etc. But was recommending using RDF/XML. He recommended an ontology called OWL to define the event. I was fine with the data, sources, etc. but kind of got confused at the OWL layer. I do want the concert and event data to be available and accessible to outside applications, so it looks like WADL will provide a much simpler way to make sure that the data is structured properly. I read through the Sun power point presentation and it seems pretty straightforward. If it continues to be supported by Google, Sun, et all, it should be a pretty safe choice. Don
Interesting overview of WADL. I've never heard of this language before. Looks like it's about to become more popular. Weight Loss Diet | Best Online Dating Service
I found this post very interesting... I have used WADL for http get and http post... I think I willneed to re-read this a few times really! Ethical
Since Yahoo, Google and Sun are implementing WADL, I think other large tech companies will follow as well. For more information on technology you can review Technology Stock News and other innovative sources for up and coming enhancements to our society. If you speak another language and need help in graspng another one quickly to learn and understand tech manuals or applications try these study abroad courses and language courses within the USA. The results can only broaden your talent with people and potential employers. I have heard a lot of news of other countires delpoying tehnology more advanced than ours earlier !! So, there is real opportunity.
I totally agree that it produces a more streamlined development process, and use its benefits on a daily basis. The holiday letting industry uses this software extensively and we use it on our site to help advertise Ski chalets in Europe. The superior coding qualities help sites build advertising networks quickly. This is of paramount importance in the industry of holiday home advertising. I thank you for your clear, concise information.

I don't see any point in this at all. Some normal readable documentation should be just fine. I do not believe we need to go to such lengths to describe REST API's Clenbuterol Weight Loss

I wrote a couple of blogs(A RESTFull WSDL?,WADL, REST and WSDL,WSDL 2.0 - a REST Friendly Language) about the need of a service message description for REST. One solution is actually WSDL, and WSDL 2.0 may even fit better. There I explain that WADL, to me, it not a clear way to describe a service, but it is more a detailed way to describe interaction. The level is lower than describing a web service, and thus closer to implementation than to contract description. Following this, WSDL is not replaced by WADL, but may be complemented by it. A WSDL may define the service, and a WADL generated from it to actually describe a REST implementation of the web service. William Martinez
