 The OpenAIRE scholarly graph is a collection of interlinked objects represented according to a given schema where both nodes and edges in the graph conform to it. The schema declares the set of properties that characterize each entity type as well as the properties that allows to characterize the edges. The schema is defined in the maven module `dhp-schema`.
 
-Each materialzation of the Graph **G_** is encoded as a set of files and directories, one directory per entity type, plus one directory holding all the relationships. Note that although the schema includes a hiearachy of entities (e.g. Publication is a subclass of Result), only actual classes materialize as tables. Each file contains newline-delimited JSON records, produced by the serialization of each corresponding object.
