kuvausmetatiedot

Kuvausmetatiedot, or descriptive metadata, are a type of metadata that provides information about the content of a resource. Unlike administrative metadata, which focuses on the management and technical aspects of a resource, descriptive metadata is concerned with the intellectual content. It is used to describe the who, what, when, where, and why of a resource, making it easier for users to discover, understand, and use the resource.

Descriptive metadata can be found in various formats, including Dublin Core, MARC, and MODS. Each format has its own set of elements or fields that are used to describe a resource. For example, in the Dublin Core format, common elements include title, creator, subject, description, publisher, contributor, date, type, format, identifier, source, language, relation, coverage, and rights.

Descriptive metadata is crucial for digital libraries, archives, and other information systems. It helps in cataloging and indexing resources, enabling search and retrieval functions. It also supports interoperability between different systems by providing a standardized way to describe resources.

Creating descriptive metadata requires a good understanding of the resource and the context in which it is used. It is often created by librarians, archivists, or other information professionals. However, with the rise of user-generated content and the need for more dynamic and flexible metadata, there is also a growing interest in crowd-sourced and automated metadata creation.

In summary, kuvausmetatiedot is a vital component of information management, providing a structured way to describe and access digital resources. It plays a key role in the functioning of digital libraries, archives, and other information systems.
