ADAPT TCD Researchers Publish Study on Improving Documentation of Declarative Mapping Projects

01 May 2026

Researchers at the ADAPT Centre and Trinity College Dublin’s School of Computer Science & Statistics have published new work addressing a key challenge in semantic data integration.

In their latest paper, MMV: A Lifecycle-Based Ontology for Declarative Mapping Projects, Sarah Alzahrani and Prof. Declan O’Sullivan introduced the Mapping Metadata Vocabulary (MMV), a framework designed to improve how declarative mapping projects are documented and understood.

Declarative mappings play a central role in enabling interoperability across diverse data sources, supporting tasks such as ontology alignment, data uplift, and interlinking. However, such projects are typically documented only through their final outputs, with limited structured insight into how they were developed.

The MMV ontology addresses this gap, capturing metadata across the full lifecycle of a mapping project, from initial analysis and design through to development, testing and ongoing maintenance while reusing established Semantic Web vocabularies. 

The paper outlines the design of MMV, demonstrates how it can be applied in practice, and sets out plans for expert evaluation.
