N0393

If you are drafting a piece to align with or describe this model, your content should focus on these core structural and semantic principles: Core Concepts of the N0393 Reference Model

: Section 6 of N0393 describes how to define constraints and semantics for specific applications. A TMA definition uses the model's primitives to specify:

: Unlike some other syntaxes (like XTM) that allow for "lazy" references, the TMM requires reification to preserve integrity when maps are merged. If you are drafting a piece to align

: Conformance to N0393 is often considered a matter of subjective human judgment rather than something easily verifiable by automated software alone.

: N0393 defines a specific information modeling language consisting of three primary primitives: topics , properties , and assertions . : N0393 defines a specific information modeling language

: The kinds of relationships that can exist between topics. Role Types : The parts topics play within those assertions.

: How to handle situations where two topics are determined to represent the same subject. : How to handle situations where two topics

: Efforts to "draft a piece" regarding N0393 often involve the Standard Application Model (N0396) . Alignment requires separating purely structural material from the material that defines higher-level semantics, like "Occurrence-ness". Drafting Considerations
