Metadata


Data about a document


In Next®, we group all documents into document types - or item types.

Each type of documents has its own set of data fields, also known as "metadata".

Originally, each data field was defined where ever it was used, but going forward we have introduced the centralized Metadata repository.

With Next®, metadata are predefined by Nextway as part of a standard, best-practice solution. And, can be customized towards individual customer needs.

Definitions

Different types of metadata exist:

  • Descriptive metadata
  • Structural metadata
  • Administrative metadata
  • Reference metadata
  • Statistical metadata

Descriptive metadata
Descriptive metadata is descriptive information about a resource. It is used for searching, filtering and identification. Examples are elements such as title, abstract, author, and keywords.

Structural metadata
Structural metadata is metadata about containers of data and indicates how objects are put together, for example, how pages are ordered to form chapters. Examples are types, versions, relationships and other characteristics of digital materials.

Administrative metadata
Administrative metadata is information to help manage a resource, like resource type, permissions, and when and how a document was created.

Reference metadata
Reference metadata is information about the contents and quality of statistical data.

Statistical metadata
Statistical metadata, or process data, describe processes that collect, process, or produce statistical data.
