Metaadatstruktúra

Metaadatstruktúra refers to the way metadata is organized and structured. Metadata, which is data about data, requires a defined framework to ensure its consistency, usability, and interoperability. This structure dictates how descriptive, administrative, and technical information about a resource is cataloged and accessed. Common structural approaches include hierarchical models, flat structures, and relational databases.

In a hierarchical structure, metadata elements are arranged in a tree-like fashion, with parent-child relationships defining the scope and context of different pieces of information. This is often used for large collections where resources can be categorized into broader and narrower groups. A flat structure, on the other hand, presents metadata as a simple list of attributes, without inherent relationships between them, which can be suitable for simpler datasets. Relational database structures store metadata in tables with predefined relationships, allowing for complex queries and linking of related information across different resources.

The choice of metaadatstruktúra is crucial for effective metadata management. It impacts how easily metadata can be created, searched, updated, and exchanged. Standards like Dublin Core or ISO 19115 provide common vocabularies and structural guidelines, promoting consistency across different systems and applications. A well-defined metaadatstruktúra enables better discovery, preservation, and reuse of digital assets and information resources.
