lisämetatiedot

Lisämetatiedot, also known as extended metadata, refers to descriptive information that goes beyond the basic or core metadata of an object or resource. While core metadata typically includes essential identifiers and administrative details, lisämetatiedot provides richer context, deeper categorization, and more granular descriptive elements. This can encompass a wide range of attributes depending on the domain. For instance, in a digital library context, core metadata might include title, author, and publication date, whereas lisämetatiedot could include subject headings, keywords, summaries, abstracts, physical dimensions, preservation status, rights management information, or even user-generated tags.

The purpose of lisämetatiedot is to enhance the discoverability, usability, and management of resources. By providing more detailed information, it allows for more precise searching and filtering, enabling users to find relevant content more efficiently. It also aids in the long-term preservation and understanding of digital assets by documenting their characteristics and context. The implementation and complexity of lisämetatiedot vary significantly. In some systems, it might be structured using predefined schemas and controlled vocabularies to ensure consistency. In others, it can be more flexible, allowing for free-text descriptions or user-contributed annotations. The term emphasizes the supplementary nature of this information, distinguishing it from the fundamental data that defines an object.
