语义Web

2007 is the make-or-break year for the Semantic Web.2007年是精心部署,为打破一年语义Web. The specs are done.正在做的规格. The tools are in place, and there's still not a whiff of a killer app anywhere to be seen.工具都到齐,还有一个杀手没有味道预检地方待观察. The Achilles heel of the Semantic Web may well be the complete disinterest of most authors in producing anything remotely approximating metadata for their pages.<语义Web的致命伤可能是最完整的冷淡产生什么作家遥他们逼近数据页. Search engines have learned to ignore any user-created metadata because honest publishers don't bother with it and dishonest spammers abuse it.忽视任何搜索引擎了解用户的数据,因为诚实创造了出版商不要理会滥发电邮及不诚实儿. Screen readers don't even bother with the limited semantics already in HTML, trying instead to figure out what the page looks like.屏幕读者甚至不中听的语义已经在有限的HTML、反而试图搞清楚页样子.

If publishers can't be relied on to provide metadata, then where can you get it from?如果不能靠出版商提供数据,那么它从哪里得到? How about from the data itself?从数据本身如何? Gleaning Resource Descriptions from Dialects of Languages (GRDDL) is the first Semantic Web technology that does away with the notion of publishers generating their own metadata.抓资源描述语言从方言(grddl)语义Web技术是第一概念,摒弃了出版商自行发电数据. GRDDL consults XSLT stylesheets supplied by third parties to scrape the metadata off Web pages.XSLT的样式由grddl征询第三方的数据刮过网页. The output from these stylesheets are Resource Description Framework (RDF) triples that you can process with the underutilized RDF toolset.输出样式都是从这些资源描述框架(RDF)的过程中,你会以三倍的工具箱RDF的不足. Different stylesheets can be applied to different sites as needed.不同样式可以根据需要应用于不同地点. Indeed, different consumers can use different stylesheets that provide the information they find of most value.事实上,不同消费者可以使用不同的样式,提供有关资料发现,大部分的价值.

It's a clever plan, and it seems like it might work (which is more than I can say for most of the Semantic Web).它的高明计划仿佛它可能与工作(即超过我可以说,大部分的语义Web). But this is the last chance.不过这是最后的机会. If GRDDL can't make the Semantic Web happen, nothing can.如果不能使语义Webgrddl发生不了.
