  • API: Application Programming Interface: a set of protocols and instructions that determine how two software components will communicate with each other. 
  • Assessment Rubric: A narrative that describes the features of a digital object, repository, etc. that should be tested, why, and using what metrics/tests and how to interpret/value the result of each test applied. These are built on a community-by-community basis. the Rubric will act as the foundation for the definition of a FAIR Assessment. This may become the place where we define minimal levels of FAIRness.


  • DMP: Data management plan as a document (any type) or stored/represented within a DMP platform
  • DMP Evaluator: A conceputal component that takes a DMP as input and outputs as a result measurements indicating if the DMP meets given compliance requirements. These requirements depend on the evaluation scenario but consists of measurements for subsets of information contained in a DMP. Such measurements can be FAIRness of included digital objects (such as datasets), compliance of the DMP with the DCS standard, automated measurements of funder requirements such as existence of relevant information and their allowed values. To provide these measurements the DMP Evaluator coordinates the inclusion of the result of other evaluators and resolves information contained in a DMP through SKGs and other sources.
  • DMP platform: Platform, tool, or service (software system) for data management planning, producing data management plans (DMPs) and potentially also machine-actionable data management plans (maDMPs).


  • FAIR Assessment: The application of a set of one or more FAIR Tests against a digital resource.
  • FAIR Metric: A narrative description of a (fine-grained) behavior/set of behaviors that is expected from a particular type of digital object, for a particular community, including how to invoke the behavior, how to observe the behavior, and what is considered “pass” versus “fail”. 
  • FAIR Test: A piece of software code that implements a FAIR Metric.
  • Fair Test Result: Output of a FAIR test over a resource, including provenance metadata about the process followed in the assessment.
  • Fair Test Result Set: A set of FAIR test results, together with their respective metadata. Common metadata may describe the set. For example, if all results where run by a request to the same API.


  • SKG: For the purpose of the OSTRails project, an SKG is defined as any database/repository with information pertaining to research products, process and actors & agents which is able to present a graph type view on this information via a suitable API
