Create a common vocabulary for the markup of web pages with the aim of facilitating the identification of contents to spiders (the small software that a search engine uses to search and analyze the contents of web pages).
This is the new web project that a strange trio is working on: Google, Yahoo and Bing, together for the first time. The objective of schema.org (this will be the name of the site) is clear: to improve the results of searches made by users.
The initiative will therefore be strongly oriented towards the semantic web and will try to favor the cataloging of contents on the basis of the respective categories they belong to in a completely automatic way.
The reason for this strange joint venture is simple: the creation of different languages would create inconvenience for developers interested in obtaining the best possible indexing for their pages, who will thus be able to use a single common language instead. The aim of the initiative is to allow users to carry out searches capable of returning more reliable results: by entering the title of a film in the search engine, for example, it will be possible to obtain reviews, or other information according to your needs, excluding anything that may be superfluous. In fact, if at the moment the search for a film review is strongly linked to the presence of the term "review" in the search text, the creators of schema.org hope that one day there will be a "tag" to specify whether a portion of text represents a specific type of content.
However, it must be said that the idea is not new: a search engine already exists (http://www.wolframalpha.com/) oriented in this direction, which however never managed to take off. We can bet that the "triumvirate" will have better luck, given the much wider media impact it can command.
