Metadata Integration with Labeled-Property Graphs

The work reflects on the use case developed by FREYA project that employs labeled-property graph for the integration of metadata from diverse sources. The role of persistent identifiers in metadata integration is discussed, and a solution is proposed for the dynamic characterization of the integrated graph. The result of this characterization can be considered a metadata model for the labeled-property graph and can be used for the graph exploration, the graph content monitoring, also for the graphs comparison and for the automated generation of machine interfaces (APIs).
