melléktaggal

Melléktaggal is a term used in metadata tagging to describe an auxiliary or supplementary tag attached to a primary tag within a dataset. It denotes secondary contextual information that accompanies a main label without altering the core categorization.

Etymology and terminology: The word appears to be formed from mellék-, meaning auxiliary or supplementary, combined with tag) and the instrumental suffix -ga/-gel, yielding a construction akin to "with an auxiliary tag." It is primarily discussed in the context of Estonian-language discussions of data annotation and metadata schemas.

Usage and function: In practice, melléktaggal refers to notes or tags that provide extra context for a primary tag. This can include provenance, confidence level, temporal applicability, or domain-specific qualifiers. In a digital library or content management system, an item might carry a main tag such as "historical document" and a melléktaggal like "region: Baltic States" to supply supplementary context for search and filtering without changing the main category.

Relationship to other tagging practices: Melléktaggal is distinct from nested or hierarchical tagging, where subcategories become part of the primary tag structure. Instead, it functions as an auxiliary layer that enhances interpretability and searchability by encoding ancillary information alongside the primary tag.
