What still belongs to a single node?
An organization, brand, product line, branch or person can be merged or split incorrectly.
DIO brings digital identity work into entity resolution, knowledge graphs, RAG, enterprise data and knowledge products. The current offer is a technical or research pilot and co-development—not finished software.
The technical problem
It emerges from the configuration of boundaries, aliases, attributes, relationships, sources and uncertainty. DIO asks whether different systems can use them to build compatible views of the same entity.
An organization, brand, product line, branch or person can be merged or split incorrectly.
Abbreviations, transliterations, historical names and language variants must be connected without erasing meaningful distinctions.
Conflicts among sources require temporal, contextual and provenance frameworks—not arbitrary preference.
An incorrect edge can alter identity as materially as an incorrect node value.
Confidence in a reconstruction depends on a source’s traceability, role and currency.
Uncertainty should be visible and managed; false precision merely moves the error into the next layer.
Diagnostic taxonomy
The taxonomy follows MVDIO and organizes individual anomalies into a multi-level system. A single reconstruction may exhibit several failure modes at once.
Entity Substitution replaces the referent. Merge Failure merges distinct entities. Split Failure splits one entity across multiple nodes. Entity Omission omits part of a reconstruction even though it was available to the system.
Semantic Fragmentation preserves the entity’s referential unity, but its representations no longer form a mutually compatible semantic whole.
Temporal Discontinuity breaks the continuity of identity. Temporal Misalignment reconstructs the correct referent in the wrong temporal state.
Contextual Displacement foregrounds an aspect that may be factually supportable yet is inadequate to the particular question, role or environment.
Describes an aggregate collapse of reconstruction rather than another item within the taxonomic hierarchy.
Expresses a reconstruction’s susceptibility or resilience to a shift in meaning. It sits outside the failure-mode hierarchy.

The DIO perspective
A pilot defines which entity the system is resolving, from which representations, through which relationships and at what level of confidence. Only then does it make sense to measure change.
Technical or research pilot
The goal is not to bolt DIO onto every system as another general framework. It is to test whether its operational core improves decisions in one precisely bounded entity problem.
Entity type, boundaries, identities of adjacent nodes, aliases and the conditions under which the system should distinguish or merge records.
Current inputs, sources, relationships, rules, conflicts and observed error patterns.
The relationship between what is claimed about the entity, where it originates, how it propagates and how the target system interprets it.
Adjustment of selected rules, data links, source hierarchy, context or uncertainty handling.
Pre/post comparison, control cases, error analysis, transferability and a decision to repeat or narrow the work.
What can be measured
Metric selection is part of the pilot. Without access to the target environment, no single set of measures can be claimed to suit every application.
Precision, recall or a domain-appropriate error matrix over pre-labeled cases.
The share of attributes and relationships with a documented conflict resolution and temporal context.
The ability to trace a claim to its origin and explain why it received a given weight.
Whether the identity change reduces manual corrections, risk or the time needed for a specific task.
Limits of the current offer
The site presents a methodological core and a prepared technical pilot. A dashboard, API and automated monitoring are possible product forms for a setting in which the pilot documents a repeatable problem and stable decision logic.
Problem definition, baseline, entity and evidence model, intervention and evaluation.
Repeatable checks for specific identity failures in a clearly defined environment.
Technical integration of validated rules into the partner’s existing data infrastructure.
A suitable co-development partner
DIO for AI and entity data
The first discussion should define the system, entity, error pattern, available data, possible intervention and how useful change will be recognized.
