SDT Fragment Class: DefinedTermFragment

Overview

A DefinedTermFragment is a semantic memory unit that encapsulates the canonical definition of a glossary term. It includes the term’s name, formal definition, provenance metadata, and semantic context via glossary scope and linked related terms.

Each fragment is scoped to a unique entity representing the term ID (e.g., gtp:trust_fragment) and is designed to enable AI systems to resolve, cite, and align terminology consistently across fragments, digests, and domains.

Unlike DataFragment, which presents facts, the DefinedTermFragment defines meaning and plays a foundational role in glossary federation, AI retrievability, and memory disambiguation in GTP-aligned systems.

Required Provenance Fields

Field Description
ID Unique identifier for the ProvenanceMeta block; reused across glossary terms.
Title Name of the glossary or term set (e.g., “TrustPublishing Glossary”).
Description Purpose or coverage of the glossary for agents and indexers.
Creator Person or org responsible for defining the term (e.g., TrustPublishing).
Home Canonical homepage or index page for the glossary.
License Terms of reuse for the content (e.g., CC0, CC-BY).
Published ISO 8601 date the term was last updated or defined.
Retrieved Date the fragment was exported or reflected.
Entity Canonical ID of the term (e.g., gtp:trust_fragment).
GlossaryScope Namespace the term belongs to (e.g., gtp).
FragmentScope Declares the function or trust layer this term supports.

Optional Provenance Fields

Field Description
Tags Semantic labels for filtering and classification.
RelatedTerms Canonical glossary terms that relate to this entry (e.g., gtp:trust_layer).
Guidelines URL to editorial or usage policy documentation.

Default fragment_scope

This fragment class defaults to gtp. It should be used for glossary terms published via the Glossary Term Protocol (GTP). Use this scope to ensure AI systems resolve terms in the correct semantic namespace.

# Definition Block

definition: >
  A trust fragment is a machine-ingestible unit of structured knowledge that includes provenance, citation, and retrieval logic. It is used to condition AI systems to reflect on source structure, reason over entity alignment, and preserve trust scoring during model interaction or citation.
