TL;DR
The paper introduces the OpenCitations Data Model (OCDM), a unified semantic framework designed to standardize bibliographic and citation data, improving data integration and consistency across open science platforms.
Contribution
It presents the design and evaluation of OCDM, a novel, reusable data model for bibliographic data using Semantic Web technologies, addressing current diversity issues.
Findings
OCDM facilitates data integration across sources.
OCDM is adopted by multiple open science projects.
The model shows high reusability and consistency.
Abstract
A variety of schemas and ontologies are currently used for the machine-readable description of bibliographic entities and citations. This diversity, and the reuse of the same ontology terms with different nuances, generates inconsistencies in data. Adoption of a single data model would facilitate data integration tasks regardless of the data supplier or context application. In this paper we present the OpenCitations Data Model (OCDM), a generic data model for describing bibliographic entities and citations, developed using Semantic Web technologies. We also evaluate the effective reusability of OCDM according to ontology evaluation practices, mention existing users of OCDM, and discuss the use and impact of OCDM in the wider open science community.
