definitionsregion

Definitionsregion is a term used in information design and knowledge representation to describe a defined portion of text, data, or a digital resource that contains formal definitions, terms, or axioms. It functions as a definitional boundary within a document, dataset, or ontology, separating explanatory content from other material such as narrative text or procedural instructions.

Characteristics of a definitionsregion include explicit boundaries, consistent formatting, and a clear mapping to identifiers, examples, and usage notes. It is often designed to support linking to terms in other regions, such as glossaries or ontologies, and may be produced or extracted by semi-automated tools that pull definitions from surrounding content.

In practice, a definitionsregion can appear in different forms. In standards and technical documents, it may be a glossary block at the front or a dedicated section embedded within the document. In software and data schemas, it may manifest as a definitions module or object containing term-name to definition mappings, synonyms, data types, and related notes.

Purpose and importance include reducing ambiguity, enabling reliable search and retrieval, and supporting automated reasoning or semantic interpretation. While the exact implementation varies by domain, the underlying idea is to centralize and standardize definitional material to improve clarity and interoperability.
