CCCEV 2.0.0

4 months ago

This page describes version 2.0.0 of the Core Criterion and Core Evidence Vocabulary (CCCEV) specification, which is the latest release addressing all the comments and recommendations received during the public review period.

The following fundamental modelling changes have been implemented in CCCEV version 2.0.0:

  • Introducing common distinct kinds of Requirements
  • Allowing requirements to be described in more detail to support machine-based decision making
  • Supporting multiple request-response patterns by sharing facts or more complex interaction patterns
  • Shifting the description of the different possible ways to fulfil a (Criterion) Requirement from the Requirement side to the Evidence side
  • Making Evidence a subclass of dcat:Dataset

More information about these changes is available in the changelog on GitHub.

During the revision period new “Principles for creating good definitions” were introduced by the SEMIC action, which are available on GitHub. Based on these rules, the definitions of the Core Criterion and Core Evidence Vocabulary have been reviewed.

About CCCEV

Similarly to all the Core Vocabularies, the Core Criterion and Core Evidence Vocabulary (CCCEV) is "a context-neutral data model that captures the fundamental characteristics of an entity". A Core Vocabulary specifies a semantic data model covering a set of use cases across domains. The specification consists of terms with a minimal set of constraints (recommended codelists, usage guidelines, etc.).

The Core Criterion and Core Evidence Vocabulary is designed to support the exchange of information between organisations or persons (more generally Agents) defining Requirements and organisations or persons responding to these Requirements by means of structured or unstructured Evidences.
