What are metadata?
Metadata is basically data on other data. Metadata, also known as methangage, can be used in any medium to describe the content of information. The idea of metalunguage is to provide documentation or information about a specific data set. If a document, image or other data type is created, certain parameters must be added behind the item. They may include elements and attributes such as the name, size or type of file. It may also represent the location or ownership of the file between any other information that needs to be noted about data content.
Metadata is stored with a file at different levels of granularity. Granularity is essentially the detail of which this data is stored. Metadata can be formatted to a low level of granularity where one data line is determined. It can also be more complex, with multiple lines of data stored in a detailed structure, such as a database.
Using metadata includes books, photos, audio files and websites. Books would be givenY with name information, author, date of publication and perhaps a unique identifier, such as the International Standard Book number (ISBN). Photos usually include the time and date it was taken. Digital cameras often record data on standardized format data that is interchangeable with different brands. Similarly, digital audio files names albums, song names, year of publication and often genre. The website usually contains the most complicated metal. Hypertext Markup Language (HTML), which consists of websites, contains everything from simple texts to data and keywords. Metalunguage may include page headers and is Geotagged with coordinates for their location. Hypertext, which connects websites, also uses metanguage.
Using Metalonguage accelerates search and localizacimnoho sources. On the Internet there are data about AIDS data in search queries via web browsers such as Google and Yahoo! Allows the user to save time in the searchinformation. The web browser automatically downloads Metalunguage, so it is part of the search process.
Often metadata is formatted into a hierarchical system called "Scheme". Some data elements are used as descriptors for other data elements. This system can basically continue eternally at many levels. Data data format is usually stored in a central location known as a register of metadata and helps organizations to standardize their data. However, most files do not require such extensive information.
The origin of the metadata language comes from the Greek prefix meta , which describes it is among something.
