10. MEM/FWU Roundtrip Plan

SkillPilot treats Metadata for Educational Media (MEM) and FWU-DE/lehrplan-ontologie as an adjacent semantic metadata and provenance layer rather than a competing model, acting as a practical open-source test bench for traceable AI learning-step navigation (see the operational pipeline in MEM/FWU Roundtrip Pipeline and reference paper https://aifyer.com/ki-lernbegleitung/versions/v1.0/schulisch-verantwortete-ki-lernbegleitung-v1.0.pdf).

10.1. Semantic Roundtrip Probe and Required Coverage

SkillPilot skill landscape (JSON export ZIP)
  -> MEM/FWU-first RDF/OWL bundle + hashed binary sidecars
  -> Reconstructed SkillPilot skill-landscape data (no source JSON access)
  -> Deterministic SkillPilot graph, view, and asset validation

Without embedding opaque JSON blobs or Base64 media literals, the semantic bundle preserves:

  • Goal identity (id, shortKey, title, description), atomic/cluster classification, weight, core, and dimension metadata;
  • Direct contains composition and didactic requires prerequisites;
  • Program structure (programUnits), goalPlacements, competency axes (competencyCatalog, competencyRefs), and learner-facing composition views;
  • Official source/provenance references plus goal-visualization references (schema:ImageObject) paired with byte-identical SHA-256 image sidecars (learner mastery state stays strictly outside public curriculum bundles).

10.2. Core-First FWU Alignment and Application Profile

| Relation / Concept | Core-First RDF/OWL Representation & Constraints | | –- | –- | | Didactic requires | Specialized reified LP_0000554 resource attached via LP_0030071 (hat Verweis) and pointing to the prerequisite via LP_0030072 (verweist auf, introduced in FWU-DE/lehrplan-ontologie#9). Generic CE-Verweis links must never be misread as prerequisites. | | Curricular contains | BFO_0000051 (hat Teil) only for genuine curricular part-whole relations, paired with skillpilot:containsGoal on every authored direct edge so transitive BFO reasoner inferences never obscure direct edges (mixed practice/exam/memory/navigation edges use only skillpilot:containsGoal). | | Minimal application terms | skillpilot:{LearningGoal,AtomicGoal,ClusterGoal,containsGoal,weight,core,shortKey,ProgramUnit,GoalPlacement,CompositionView,GoalVisualizationReference} plus schema:ImageObject for binary sidecars. | {cols="28%,72%"}

Success requires full SkillPilot validator conformance (acyclic requires/contains, referential integrity, valid composition views), deterministic field equivalence, OWL 2 DL / structural core validation, and byte-identical image SHA-256 verification without hidden access to the original JSON input.
