Whois & Analysis for schema.org

Schema.org is an initiative launched on 2 June 2011 by Bing, Google and Yahoo! (then operators of the world's largest search engines) to “create and support a common set of schemas for structured data markup on web pages.” In November 2011 Yandex (whose search engine is the largest one in Russia) joined the initiative.

They propose using the schema.org vocabulary along with the Microdata, RDFa, or JSON-LD formats to mark up website content with metadata about itself.

Such markup can be recognized by search engine spiders and other parsers, thus gaining access to the meaning of the sites (see Semantic Web).

The initiative also describes an extension mechanism for adding additional properties.

Public discussion of the initiative largely takes place on the W3C public vocabularies mailing list.

A web search engine is a software system that is designed to search for information on the World Wide Web.

The search results are generally presented in a line of results often referred to as search engine results pages (SERPs).

The information may be a mix of web pages, images, and other types of files.

Some search engines also mine data available in databases or open directories.

Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler.

A data model (or datamodel) is an abstract model that organizes elements of data and standardizes how they relate to one another and to properties of the real world entities.

For instance, a data model may specify that the data element representing a car be composed of a number of other elements which, in turn, represent the color and size of the car and define its owner.

A web page (webpage or Web page) is a document that is suitable for the World Wide Web and web browsers.

A web browser displays a web page on a monitor or mobile device.

The web page is what displays, but the term also refers to a computer file, usually written in HTML or comparable markup language.

Web browsers coordinate the various web resource elements for the written web page, such as style sheets, scripts, and images, to present the web page.

An application program (app or application for short) is a computer program designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user.

Examples of an application include a word processor, a spreadsheet, an accounting application, a web browser, a media player, an aeronautical flight simulator, a console game or a photo editor.

The collective noun application software refers to all applications collectively.

This contrasts with system software, which is mainly involved with running the computer.
