CCMM (Czech Core Metadata Model for Research Data) is the base metadata model for describing research data in the Czech Republic and is an output of the CARDS project.
The model is built on existing metadata schemas, primarily DCAT-AP and DataCite, and to a lesser extent incorporates elements from DCAT-AP-CZ and Dublin Core.
The aim of CCMM is to define general elements for describing datasets that can be applied across different data repositories and to ensure the interoperability of core metadata across disciplines.
The foundational model will serve as a basis for unified metadata search in the National Metadata Directory (Národní metadatový adresář, NMA, in Czech), i.e. it will function as an exchange format among repositories within the Czech National Data Infrastructure (NDI), the National Repository Platform (NRP), and the National Metadata Directory (NMA).
CCMM and information about its documentation can be found on the Documentation page. The model and the vocabularies used are available on GitHub. The model is published under the CC BY license.
