Metadatastandardid

Metadatastandardid is a field used in metadata records to identify the metadata standard applied to describe a resource. Its primary role is to enable interoperability by signaling to consuming systems how the metadata is structured and which elements and rules govern its interpretation. By providing a machine-readable pointer to the standard, metadatastandardid helps ensure consistent processing across catalogs, repositories, and data portals.

The value of metadatastandardid is typically a persistent identifier, such as a URI, or a compact code that names the standard. Formats vary by model, but common forms include a full URI that resolves to a registry entry for the standard or a short code like a standard name (for example, a name such as "DublinCore" or "ISO19115"). In many implementations, metadatastandardid is paired with a metadatastandardversion field to indicate the exact version of the standard in use.

In practice, metadatastandardid is used to advertise which standard governs a metadata record, guiding tools in applying the correct interpretation rules for elements such as title, abstract, keywords, and spatial or temporal information. It supports data discovery, validation, and interoperability by making the applicable metadata framework explicit to users and software.

Best practices include keeping identifiers stable, referencing an authoritative registry, documenting any mappings between local practices and the standard, and including both the identifier and a human-readable name where helpful. In schema design, metadatastandardid is typically represented as a string value.
