Metadata Meaning: Meta-data is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of meta-data, including:
Metadata means "data about data". Although the "meta" prefix means "after" or "beyond", it is used to mean "about" in epistemology. Meta-data is defined as the data providing information about one or more aspects of the data; it is used to summarize basic information about data which can make tracking and working with specific data easier.
Some examples include:
For example, a digital image may include meta-data that describes the size of the image, its color depth, resolution, when it was created, the shutter speed, and other data.
A text document's meta-data may contain information about how long the document is, who the author is, when the document was written, and a short summary of the document.
Metadata within web pages can also contain descriptions of page content, as well as key words linked to the content.
These links are often called "Metatags", which were used as the primary factor in determining order for a web search until the late 1990s. The reliance of metatags in web searches was decreased in the late 1990s because of "keyword stuffing". Metatags were being largely misused to trick search engines into thinking some websites had more relevance in the search than they really did.
Metadata can be stored and managed in a database, often called a meta-data registry or metadata repository.
However, without context and a point of reference, it might be impossible to identify meta-data just by looking at it.
The term "meta-data" was coined in 1968 by Philip Bagley, in his book "Extension of Programming Language Concepts" where it is clear that he uses the term in the ISO 11179 "traditional" sense, which is "structural meta-data" i.e. "data about the containers of data"; rather than the alternative sense "content about individual instances of data content" or metacontent, the type of data usually found in library catalogues.
Since then the fields of information management, information science, information technology, librarianship, and GIS have widely adopted the term. In these fields the word meta-data is defined as "data about data".
