This report documents the work undertaken within project Task 4.7 Modeling the SSHOC data life cycle and describes the process of mapping social science research metadata standards DDI Codebook and CMDI to the SSHOC Reference Ontology (SSHOCro). The resulting mapping rules are also documented.
SSHOCro is a common meta-level schema based on CIDOC CRM. By offering a conceptual model capable of describing the real-world lifecycle of data produced and managed via generic collection, connection, and interpretation workflows and associated sorting and publishing activities, SSHOCro provides a semantic interoperability framework with two key advantages for Social Sciences and Humanities researchers:
In showing researchers how to relate and combine data documented with the DDI and CMDI source schema with minimal loss of meaning and data perspective the report traces the following steps:
1.Selection of the specifications of versions and profiles for DDI and CMDI
2. Selection of the tags to be mapped into SSHOCro
3. Updating of SSHOCro, following the harmonisation process
4. Conceptual mapping process: establishing correspondences between selected elements of the DDI/CMDI and elements/full paths of SSHOCro
5. Implementation of the mappings between selected research datasets documented with CMDI/DDI and SSHOCro
