Sekundäärimeta

Sekundäärimeta refers to metadata that is derived or generated from primary metadata. Primary metadata describes a resource directly, such as the author of a document or the date of creation of a file. Sekundäärimeta, on the other hand, is created by processing or analyzing the primary metadata. Examples include information about the usage of a resource, such as how often it has been accessed or downloaded, or aggregated statistics about a collection of resources. It can also include derived relationships between resources, like a citation index showing which documents cite a particular paper.

The purpose of sekundäärimeta is often to provide context, facilitate discovery, or enable new functionalities. For instance, usage statistics can help in evaluating the popularity or importance of a resource. Derived relationships can reveal connections within a dataset or a larger information landscape. Sekundäärimeta can be generated automatically through various algorithms and tools, or manually by domain experts.

The distinction between primary and sekundäärimeta is not always rigid, as metadata can evolve. What starts as primary metadata might be transformed or enriched over time, leading to new forms of secondary metadata. Understanding this distinction is important in areas like digital preservation, data management, and information retrieval, where managing and utilizing metadata effectively is crucial.
