Module: Project Record

A “ProjectRecord” class has been added to make the underlying structure explicit and to specify the semantics more formally. This concepts does not refer to observations or to the dataset holding the project observations, but to a part of a database or spreadsheet that contains a complete set of information about the project. This is a concept which was implicit in the 2017 model [[PPSR-CCM]], with a variety of characteristics which were well-defined, necessary and easily reusable. The project record, which is not essential to the representation of a project, given that all project metadata are defined and linked directly to the Project class, is basically used in catalogues and repositories of projects, such as Scistarter or BioCollect. Therefore, multiple project records can exist in different catalogues/repositories, which refer to the same project, and the “ProjectRecord” class helps the linkage among them. This class can also represent a snapshot of project information, which is used to make search and reasoning more efficient.

Class: Project Record

RDF Class:	`dcat:CatalogRecord`
Definition:	??
Usage note:	??

Property: Describes

RDF Property:	`foaf:primaryTopic`
Definition:	It associates the record with the project it refers to.
Usage note:	In a concrete implementation, the link could be through the identifier “Project.GUID”.
