Automatic synchronization of RDF graphs representing ontologies and Wikibase instances

Version control systems provide ways to ease collaboratively working on a set of source files. Due to the nature of RDF models that represent ontologies, there is a clear benefit on using those kinds of systems, and many well-known datasets and vocabularies are already being worked on collaboratively. However, there are domain experts who could provide feedback and add new knowledge to the data, but do not know how to work with version control systems or with RDF files directly. Wikibase provides a human-friendly interface with an underlying Linked Data model, and can be used as a publication service for the data where those experts can easily browse and add their knowledge. In this paper, we propose a system that automatically synchronizes RDF files hosted in a version control system with a Wikibase instance. We describe the system from an architectural point of view, and explain the main components needed for the synchronization of data. Some of the challenges for an effective synchronization of RDF files with Wikibase are also addressed. This system is currently being used as part of the Hércules project to synchronize a research ecosystem ontology with a Wikibase instance.
