Descriptive applied functional analysis griffel pdf describes a resource for purposes such as discovery and identification. It can include elements such as title, abstract, author, and keywords. Structural metadata is metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters.
It describes the types, versions, relationships and other characteristics of digital materials. Administrative metadata provides information to help manage a resource, such as when and how it was created, file type and other technical information, and who can access it. 1980s, when libraries converted their catalog data to digital databases. This metadata can automatically improve the reader’s experience and make it easier for users to find the web page online.
A principal purpose of metadata is to help users find relevant information and discover resources. Metadata also helps to organize electronic resources, provide digital identification, and support the archiving and preservation of resources. Metadata assists users in resource discovery by “allowing resources to be found by relevant criteria, identifying resources, bringing similar resources together, distinguishing dissimilar resources, and giving location information. In many countries, the metadata relating to emails, telephone calls, web pages, video traffic, IP connections and cell phone locations are routinely stored by government organizations. Metadata means “data about data”.

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. However, without context and a point of reference, it might be impossible to identify metadata just by looking at it. For example: by itself, a database containing several numbers, all 13 digits long could be the results of calculations or a list of numbers to plug into an equation – without any other context, the numbers themselves can be perceived as the data. The term “metadata” 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 metadata” i.
While this is the generally accepted definition, various disciplines have adopted their own more specific explanation and uses of the term. While the metadata application is manifold, covering a large variety of fields, there are specialized and well-accepted models to specify types of metadata. 2 similar categories: technical metadata and business metadata. On the other hand, NISO distinguishes among three types of metadata: descriptive, structural, and administrative. An example of structural metadata would be how pages are ordered to form chapters of a book. Administrative metadata refers to the technical information, including file type, or when and how the file was created. Two sub-types of administrative metadata are rights management metadata and preservation metadata.
