SYSE.7:0.1 - Terms and Distinctions
Words such as model, view, specification, requirement, data, digital thread, digital twin, traceability, and single source of truth are recognition cues. Before relying on them, restore the objects and relations that matter to the decision.
| Cue | Decision-usable interpretation in this pattern |
|---|---|
| description | One claim-bearing U.Episteme with a recoverable EntityOfConcern, claim content, effective reference scheme, edition, and current use. An expression or carrier—for example, a file, diagram, database row, screen, or spoken utterance—may carry it or be used in a publication occurrence; identify the episteme and publication relation separately. |
| model | A description episteme used under a stated modeling purpose, assumptions, omissions, interpretation, and validity boundary. Record these conditions independently of its executable, mathematical, visual, or tool form. |
| view | The same episteme individual qualifies as U.View only when a U.Viewpoint episteme and obtaining EpistemeViewpointConformanceRelation are present under E.17.0. Establish that membership through the conformance relation; presentation labels—for example, a page title, diagram type, dashboard face, or viewpointRef—remain publication cues. |
| viewpoint | A claim-bearing episteme specifying concerns and conformance rules for a view. A cue such as a stakeholder name, discipline label, screen layout, or familiar view list qualifies only when it supplies that content. |
| representation | A visible or formal expression and, when current, its correspondence to an independently recovered object, relation, claim, or mathematical structure. Treat expressions—for example, diagrams, tables, queries, graphs, or executable files—as representations. Ground performed Work through Agent–Work attribution, authority through its own relation, and depicted claims through evidence. Use C.29 for a declared mathematical-lens use and its preserved and lost structure. |
| publication | An E.24.PUB publication occurrence with its form, carrier, audience, bounded use, and selected source edition when those identities matter. Ground the described world-side relation independently and use E.17.0 when U.View membership matters. |
| engineering data | Claim-bearing epistemes and values used in engineering Work, together with the identities, editions, reference schemes, provenance, applicability, and relations needed by that use. Ground their world-side subjects separately. |
| trace or link | A recoverable direct relation: for example, a claim depends on a source claim; a test result assesses a named claim; an interface description concerns a selected configuration; or a change affects a configuration item. A hyperlink or same-name token is only an index until the intended relation and participants are stated. |
| digital thread | A maintained arrangement of description, source, configuration, change, publication, and use relations across named engineering Work. State its bounded use, participating relations, Agents assigned to maintenance Work, and currentness conditions instead of inferring them from one chain or repository. |
| digital twin | A selected description, model, data, automation, observation, and use arrangement concerning a named subject. Support every additional claim—for example, about System kind, fidelity, synchronization, beneficial use, or completeness—on its own grounds. |
| ensemble | The selected description epistemes and relations needed by one bounded set of decisions. This is an ordinary collective word. Identify each carrier and governing reference scheme independently. |
| consistency | A named set of claims can be jointly used under stated schemes, configurations, intervals, and tolerances. Establish it from claim content under those conditions; syntactic agreement, shared identifiers, and storage co-location are only comparison cues. |
| coherence | The selected claims and their correspondences support the receiving decision without an unresolved contradiction or missing distinction material to that use. Its scope is the named decision and material claims. |
The described subject, description episteme, model use, representation, mathematical lens, view, viewpoint, publication occurrence, carrier, source, evidence relation, configuration, and performed Work remain different objects. Restore only the distinctions that can change the receiving decision.
