Short answer

Design systems for cultural heritage data to support many-to-many relationships and explicitly model uncertainty, rather than forcing one-to-one mappings.

Field: User-Centred Design
Source: Journal of Documentation (2026)
Method: Case Study
Evidence: Moderate effect

Direct, one-to-one mapping of entities is insufficient for reconciling diverse cultural heritage records due to inherent ambiguities, incomplete data, and varying cataloguing traditions. This user-centred design research insight is drawn from a 2026 study published in Journal of Documentation. Using Case study, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design systems for cultural heritage data to support many-to-many relationships and explicitly model uncertainty, rather than forcing one-to-one mappings.

Key Findings

01Entity reconciliation is rarely a one-to-one operation.
02Ambiguities, incomplete data, shifting attributions, and varying practices significantly shape reconciliation outcomes.
03Observed strategies include creating anonymous/collective entities, using umbrella terms, adding uncertainty qualifiers, and acknowledging unresolvable ambiguity.

Application

Design takeaway

Design systems for cultural heritage data to support many-to-many relationships and explicitly model uncertainty, rather than forcing one-to-one mappings.

How to apply

When designing a database for historical documents, allow for multiple authors, multiple subjects, and multiple locations to be associated with a single document.

Project actions

01Consider how your design will handle situations where a single input relates to multiple outputs, or vice versa.
02Think about how to visually represent uncertainty or multiple connections in your user interface.

Method & Evidence

AimWhat are the usability challenges and effective strategies for reconciling heterogeneous entity records across cultural institutions, particularly within art historical photo archives?

MethodCase Study

ProcedureThe study analyzed reconciliation workflows and cataloguing traditions within art historical photo archives, considering institutional contexts, data granularities, and modelling strategies.

ContextCultural heritage institutions, specifically art history and photographic archives.

Variables

IVData reconciliation workflow strategies (e.g., one-to-one vs. many-to-many modelling).

DVUsability challenges and effectiveness of reconciliation.

CVInstitutional cataloguing traditions, data granularity, specific cultural heritage domain (art history photo archives).

Strengths & Limitations

Strengths

+Focuses on a real-world, complex problem in digital humanities.
+Provides practical strategies observed in practice.

Limitations

The complexity of implementing a true many-to-many database structure can be a significant technical challenge for a design project.

Reliability & validity

The study's validity is strengthened by its focus on real-world case studies within specific institutional contexts. Reliability could be enhanced by a larger, more diverse sample of institutions and data types.

Think critically

How might the 'many-to-many' nature of entity reconciliation impact the user experience and the perceived trustworthiness of the information presented?

Design Principles

"Embrace ambiguity: Design systems that can represent and manage uncertainty and complex relationships, rather than assuming perfect, singular data."

This research highlights a critical usability challenge in digital humanities and cultural heritage informatics. Designers of databases, archival systems, and research platforms must move beyond simplistic data models to accommodate the complex, often non-linear relationships found in real-world historical data.

What This Means for Your Design

When you're trying to link up information from different places, like photos and art descriptions, it's not always a simple one-to-one match. Sometimes one photo can relate to many artworks, or one artwork can have many photos. You need to design your system to handle these 'many-to-many' connections and show when information isn't perfectly clear.

How to use in your project

1.Reference this study when discussing the challenges of data modelling or user interface design for complex datasets.
2.Use the findings to justify the need for flexible relationship types in your proposed design solution.

Paragraph starter

This design project acknowledges the inherent complexities in data reconciliation, drawing upon research that highlights the inadequacy of one-to-one mapping for heterogeneous records (Daquino, Mambelli, & Kozlov, 2026). The findings suggest that systems must be designed to accommodate many-to-many relationships and explicitly model uncertainty to effectively manage ambiguous or incomplete data, a principle that will guide the development of the proposed solution.
