日子汪国真_微格式的大日子

日子汪国真

Today was a big day for Microformats - very big. First, they announced that the new value-class-pattern is ready for implementation. The value-class-pattern is a great step forward, as it provides needed accessiblity improvements, and in my opinion, gives the developer a bit more flexibility over how to structure their markup.

今天是微格式的重要日子-非常重要。首先，他们宣布新的价值类别模式已准备就绪，可以实施。值类模式是向前迈出的一大步，因为它提供了所需的可访问性改进，而且我认为，这为开发人员在如何构造其标记方面提供了更大的灵活性。

That was a pretty big announcement in its own right, and I was very pleased to see the new pattern approved and garnering a bit of buzz. That announcement, however, was trumped by Google announcing that they will be starting to index Microformats and RDFa and using that data to enrich their search results.

就其本身而言，这是一个相当大的宣布，我很高兴看到新模式获得批准并引起了一些轰动。不过，这一宣布遭到了Google的号召，他们宣布他们将开始为Microformats和RDFa编制索引，并使用这些数据来丰富其搜索结果。

Microformats has been around since 2003, but the adoption has been a bit sluggish. While overall quite easy to implement, it can been difficult to demonstrate the value of using Microformats at times due to a lack of major support, and therefore, major incentive. That shouldn’t be a problem anymore, because Google is definitely providing that major incentive.

自2003年以来，微格式就已经存在，但采用速度一直很慢。尽管总体上很容易实现，但由于缺乏主要支持，因此也缺乏主要的诱因，有时很难证明使用微格式的价值。这不再是问题，因为Google肯定会提供这一主要激励措施。

如何使用它们 (How They’ll Be Used)

Google has a good vision for how to make use of the harvested data in their results. They’ll be providing these “rich snippets”, as they’re calling them, to provide both additional content and meaning about the pages in their search results. For example, a page featuring reviews will feature the average star rating, and number of reviews the page contains, right there in the search results.

Google对如何在结果中利用收集到的数据抱有良好的愿景。他们将提供这些“丰富的摘要”，正如他们所说的那样，以在搜索结果中提供有关页面的附加内容和含义。例如，一个包含评论的页面将在搜索结果中显示平均星级和该页面包含的评论数量。

In addition to reviews, this initial launch will also provide “rich snippets” for people. Using contact information parsed from sites like LinkedIn, for example, search results may indicate a person’s job title and location, to help users determine if the results they are looking at are likely to be associated with the person they’re looking for.

除评论外，此首次发布还将为人们提供“丰富的摘要”。例如，使用从类似LinkedIn的网站解析的联系信息，搜索结果可以指示某人的职位和位置，以帮助用户确定他们正在查看的结果是否可能与他们正在寻找的人相关联。

On top of that, Google plans for to use these Microformats to allow users to be a bit more specific with their searches. An example given was that a user could search for all reviews on a printer where the average rating was over 3 stars. This allows users to tailor the content they receive by the context in which they are interested.

最重要的是，Google计划使用这些微格式，以使用户对其搜索更加具体。给出的示例是，用户可以在平均评分超过3星的打印机上搜索所有评论。这允许用户根据他们感兴趣的上下文来定制接收到的内容。

Not only does this new feature enhance the user experience, but the use of Microformats and RDFa data should also provide signifcant value for sites smart enough to markup their content using them. According to studies done by Yahoo on similar enhancements to search results, they found these kinds of improvements resulted in a significant improvement in click-through rates, in some cases up to a 15% increase.

这项新功能不仅可以增强用户体验，而且微格式和RDFa数据的使用也应为足够聪明的站点提供显着的价值，从而可以使用它们来标记其内容。根据Yahoo对搜索结果的类似增强所做的研究，他们发现这些改进导致点击率有了显着提高，在某些情况下达到了15％的增长。
