Metatietotyppejä

Metatietotyppejä, or metadata types, refer to the various categories or structures used to describe and organize metadata. Metadata itself is data that provides information about other data. Understanding different metadata types is crucial for effective data management, retrieval, and interoperability.

Common metadata types include descriptive metadata, which identifies and describes a resource, such as its title, author, and subject. Structural metadata describes the organization and relationships between components of a digital object, like the order of pages in a book or the relationship between different parts of a database. Administrative metadata provides information to help manage a resource, including its creation date, file type, and access rights. Technical metadata describes the technical characteristics of a data object, such as file format, size, and encoding. Preservation metadata records information necessary for the long-term maintenance and accessibility of digital resources.

These types often overlap and can be combined within metadata schemas. For example, a Dublin Core element like "title" is descriptive, while "format" can be considered technical. The specific types and their organization are often defined by formal metadata standards, which ensure consistency and facilitate the exchange of metadata between different systems and organizations. The choice of metadata types depends heavily on the purpose of the data and the intended use of the metadata.
