This research extends an earlier work [11], which focused primarily on social media data quality evaluation for decision making, and initial validation of metadata management architecture for big data systems.
The contribution of the paper is (an extended) RA design of metadata management layer for big data systems, which focuses on data quality management.
Grid computing systems required stronger support for file and metadata management; for workflow processing and for resource management.
The comparison with two popular relational RDF stores, Jena and Sesame, and two commercial native RDF stores, AllegroGraph and BigOWLIM, showed that our optimizations result in improved performance and scalability for provenance metadata management.
The cancer Data Standards Repository (caDSR), an ISO/IEC 11179 metadata registry [ 2], provides for reference metadata management and distribution.
Atlas [27] is an agile Apache enterprise framework for data governance and metadata management in Hadoop data lakes.
The IUGONET metadata database is already used outside the IUGONET institute, for example, as a metadata management system of the imager and medium frequency (MF) radar of National Institute of Information and Communications Technology.
Considering this need, this paper presents solutions for semantic data interoperability, distributed metadata management, and an agent-based query processing approach for supporting the exchange of learning content from different e-learning systems.
