What is the microdata?

microdata is a specification of HTML-5 to add machine-readable code to a document such as a website, and the specifications should not be confused with companies called microdata systems. All microdata is usually added to HTML brands that show information that is visible to human users. By adding information to the brands already used, the developer can indicate page content elements to make search engines and other applications easier to categorize. These labels describe the type of content, such as various aspects of products, organizations or information about people. The specification does not describe the presentation or appearance of the content. With the HTML-5 code, the developer does not mean content as an item, and then adds items such as strings, URLs, data and time to this item. And Tags are often the basic brands to add information about microdats. Like HTML, it can be nested, microdata can also be nested. Initial Dictionary Set for Item properties is to DSPosition on the website of the organization of vocabulary data.

The use of microdata is compatible with the framework of resource description (RDFA). RDFA works with expansion of XHTML attribute attributes. However, this specification is easier than RDFA specification and is part of the HTML-5 specification. The use of RDFA and microdata are forms of semantic marking.

Any microdata can be extracted for use with JavaScript Object (JSON). JSON is an interch formatAnge data, considered a bright weight that people can read. JSON can be used with asynchronous javascript and XML programming methods. These methods allow you to load web applications from the server without affecting the behavior and appearance of the website. Web 2.0 applications often use Ajax, so microdata can be useful for these programs.

search engines scan pages for content structured by microdats, so its rich snippets can represent a better information page of search results. It is particularly used to improve local search results, which consist of special search engines passing on the business lists of a specified region. The company has information on how to add this code to the HTML documents in the WebMaster tool.
