Semantic integrity
Claims, relationships and representations do not undermine one another without a visible explanation.
Ontology of Digital Identity is a distinct theoretical, terminological, research and IP layer. It examines the conditions under which digital identity becomes recognizable, stable, relationally grounded, interpretable and reconstructable.
A distinct layer
DIO engages a specific identity with an optimization objective. ODI examines the conditions under which digital identity exists, can be known and can break down—without requiring immediate application.
The two layers share concepts and the K6 model, but answer different questions. DIO asks how to intervene. ODI asks what must first be defined before identity, intervention and the resulting reconstruction can be discussed coherently.
Epistemic restraint
ODI treats digital identity as a distributed, emergent object. Different observers work from different traces and rules; the goal is therefore not a metaphysically final description, but transparent conditions for compatible interpretations.
Claims, relationships and representations do not undermine one another without a visible explanation.
It is possible to trace who created a claim, what supports it and the context in which it applies.
The distinction among data, interpretation and inference remains visible.
Different systems can arrive at compatible definitions of an entity and its relationships.
K6 as a shared language
The dimensions do not form a sequence. Any change in representation can alter interpretation, trust, relationships and the resulting reconstruction—while also redefining how the entity itself is bounded.
What is stabilized as a distinguishable interpretive node, and where its boundaries lie.
The traces, signs, data and statements through which the entity becomes present to each observer.
The meaning produced from representations within a specific mode of reading and decision-making.
How reliability, authority, evidential support and resilience to contradiction are established.
How connections to other entities, works, roles and sources anchor meaning.
How the whole is reassembled from available traces, and with what loss or uncertainty.
K6 is the operational and conceptual framework of DIO/ODI. Its universal empirical validity remains open to external evaluation.
Research agenda
ODI gains value not by expanding abstraction, but by translating concepts into research problems, metrics, domain adaptations and open expert critique.
Under what conditions do distributed traces stabilize as one entity—and when do they split into multiple nodes?
When are human, search, graph and model-based reconstructions compatible—and when are they not?
How can an identity update be distinguished from a discontinuity, conflation or illegitimate overwrite?
How should provenance and confidence affect the weight of a claim, relationship or derived interpretation?
How can we tell that a change in representation improved reconstruction rather than merely hiding an inconvenient contradiction?
Existing reference infrastructure
Reference Vocabulary v0.1.0, Reconstruction Failure Modes and Reference Model v0.3.1 connect the publication layer with a canonical namespace and open data formats.
A controlled vocabulary of concepts, definitions and relationships with persistent identifiers.
Four failure families distinguish the referential, semantic, temporal and contextual levels of reconstruction.
The published release connects concepts, model relationships, documentation and distributed artifacts.
The namespace https://vocab.danielberanek.cz/dio-odi/# gives the terms an addressable and linkable form.
Machine-readable serializations make the reference layer available to ontologies, graphs and other knowledge systems.
Application Mappings connect DIO/ODI concepts with a RAG pipeline and the Heterogeneous Entity Matching taxonomy while remaining separate from the canonical vocabulary.
Follow-on work can develop metrics and protocols, domain mappings, research projects, standardization and specifically defined licensed uses.
The reference vocabulary preserves stable meanings; application profiles can translate them into specific systems without being conflated with the canonical layer.
A suitable partnership
ODI is not looking merely for agreement. It seeks environments where its concepts can be refined, challenged and translated into usable structures.
ODI for knowledge infrastructure
The proposal should define the research or institutional problem, the available capability and the expected form of the result.
