metaadatkészletet

Metadata refers to data that provides information about other data. A metadata set, or "metaadatkészlet" in Hungarian, is a collection of such descriptive data. These sets are crucial for understanding, organizing, and managing larger datasets. They typically include information such as the source of the data, its creation date, the format it is in, its intended use, and any relevant licensing or ownership details.

The purpose of a metadata set is to make data discoverable and usable. For example, in a library, the metadata set might include the book's title, author, publication date, genre, and Dewey Decimal classification. This allows patrons to easily find the books they are looking for without having to sift through every item on the shelves. Similarly, in scientific research, metadata sets for experimental data can describe the methodology, instruments used, and parameters recorded, enabling other researchers to interpret and potentially reproduce the findings.

Metadata sets can vary significantly in their structure and complexity depending on the domain. They can be simple lists of attributes or highly structured schemas following specific standards like Dublin Core or ISO 19115 for geographic data. Effective metadata management ensures data quality, facilitates data sharing, and supports long-term data preservation. Without proper metadata, even the most valuable data can become inaccessible or misunderstood.
