It introduces a novel view layer that integrates blockchain technology to secure and optimize query processing across diverse RDF data sources.

Findings

Improved data security through blockchain access control

Enhanced query processing efficiency in heterogeneous RDF datasets

Effective management of multi-user data access

Abstract

The Semantic Web, an extension of the current web, provides a common framework that makes data machine understandable and also allows data to be shared and reused across various applications. Resource Description Framework (RDF), a graph-based data model for describing things (entities), facilitates data integration. Due to the explosion of the amount of RDF data, developing tools to support processing and answering of complex queries over the integrated data has become challenging. To overcome this challenge in query processing in semantic data integration frameworks, we provide a view layer inserted between the heterogeneous data sources and user interface layer while ensuring only authorized users are allowed access to the information. The view layer must provide a support in terms of access, integration, querying, management of data sources in a multi-user environment.
