OpenCSA大会启动SCA标准化工作

　　在提出SCA两年之后，OASIS宣布分别针对SCA的不同方面成立六个新的技术委员会。如果你还没有听说过什么是SCA，Burton的副总裁与研究领导Anne Thomas Manes为你做了总结：

　　“SCA的基本想法是以一系列服务的形式提供各种业务功能，并能够把它们联结到一起创造出满足特定业务需要的解决方案。在这些复合应用中可以包含特别为此构建的新服务，也可以重用现存系统中已有的业务功能。SCA为开发者提供容易使用的工具，让开发者将IT资产转换成可重用的服务，从而使SOA的设计过程更加顺畅。”

　　新成立的六个委员会是：SCA-Assembly、SCA-Bindings、SCA-BPEL、SCA-C-C++、SCA-J和SCA-Policy。随着SCA在各个领域的发展，还可能成立更多的技术委员会。OASIS 的标准开发领导James Bryce Clark补充说：

　　“这六个OASIS SCA技术委员会打算解决SOA项目实现中非常困难的‘最后一公里’的问题。比方说，如果一群软件工程师打算用C和BPEL把两个专门的服务整合进一个应用，他们会遇到一些艰难的设计决策。各个SCA技术委员会计划提供实质性的帮助，通过语言绑定、策略框架、代码模式等等方式。”

　　由SAP主办并与Oracle共同赞助的全体大会（Plenary）将是这些技术委员会真正开始工作的地方。会议将以“开放日”作为开始，人们可以在那里了解SCA和它带来的好处。我们曾经多次讨论过SCA，而这个话题经常引发激烈的争论。现在离SCA的发展向所有宾客（好吧，所有OASIS成员）敞开大门只剩几周了，除了最初的发起公司之外，会有多少其它人卷入其中，他们又试图在改变的道路上走多远，这些都是值得观察的有趣问题。这次大会有理由成为一次重要的事件，同时也可以从中看出人们的兴趣所在。

　　Almost 2 years after first being released on the world, OASIS announced that the formation of 6 new technical committees dedicated to the various aspects of SCA. In case you hadn't heard about SCA, Anne Thomas Manes, VP and Research Director of Burton summarizes:

　　"SCAis based on the idea that business functions are provided as a series of services that can be wired together to create solutions for particular business needs. These composite applications can contain new services created specifically for the application and reuse existing business functions from existing systems. SCAoffers the potential to streamline the SOAdesign process by enabling the delivery of easy-to-use tools developers need to transform IT assets into reusable services."

　　The 6 committeesare: SCA-Assembly, SCA-Bindings, SCA-BPEL, SCA-C-C++, SCA-J and SCA-Policy. More TCs may be created as other areas of SCAare developed. James Bryce Clark, director of standards development at OASIS added:

　　"These six OASIS SCATCs plan to address the tough 'last mile' of SOAproject implementation. If a group of software engineers want to compose two specific services into an application using C and BPEL, for example, they'll face some challenging design choices. The SCATCs plan to provide practical help, in the form of language bindings, a policy framework, and code patterns."

　　The Plenary, to be hosted by SAP and co-sponsored by Oracle, will be the place where these technical committees really get going. But there's an "open day" at the start, where people can attend and learn about SCAand the advantages it provides. We've discussed SCAseveral times in the past and it often generates heated debates. Now that there are very few weeks left before SCAdevelopment opens up to all comers (well, all OASIS members), it will be interesting to see how many people from outside the original author companies get involved and to what extent they try to push changes. The Plenary will be a very important event for several reasons, as it will act as one measure of interest.
