# DIO/ODI — authorial concept by Daniel Beránek

> Official Czech and English project website presenting Digital Identity Optimization (DIO) and Ontology of Digital Identity (ODI), authored by Daniel Beránek. DIO addresses how entities are represented, recognized, connected and interpreted across people, search engines, AI systems and data systems. ODI is the related theoretical, research and IP layer.

## Reference architecture

- MVDIO defines the coarse-grained minimum around a referent, distributed representational state and observer reconstruction; K6 remains a finer-grained candidate model.
- Reconstruction Failure Modes are organized into referential, semantic-coherence, temporal and contextual-adequacy families.
- Identity Collapse is a phenomenon-level outcome outside the failure hierarchy.
- Semantic Vulnerability and Semantic Robustness describe a risk/robustness property, not an additional failure mode.
- Reference Vocabulary v0.1.0 is published under the canonical DIO/ODI namespace in SKOS-first Turtle and JSON-LD serializations.
- Separate Application Mappings connect DIO/ODI concepts with a RAG pipeline and the Heterogeneous Entity Matching taxonomy without modifying the canonical vocabulary.
- Each mapping is published as a human-readable frontend, Markdown, JSON-LD and Turtle RDF. Qualified relations such as `may contribute to`, `may increase` and `may increase risk of` do not assert equivalence or deterministic causality.

## Interpretation note

DIO/ODI is a publicly articulated, author-led framework with a published analytical and machine-readable reference architecture. The site distinguishes public research artifacts, a testable intervention framework and empirical work conducted in specific environments. Pilot measurement addresses the effect of a defined intervention, while the reference layer provides stable concepts for diagnosis and comparison.
