eTDRis a service provided to ensure that digital scientific information remains findable, accessible, interoperableand reusableover time. It includes capacity/resource planning and application oflong-term preservation techniques/technologies. It also combines policies, processes and actions to ensure access to “born-digital” and reformatted data, regardless of the challenges of technological changes or failures (metadata, file format, media). The eTDR data repository is certified as Trusted Digital Repository.
The instance of eTDRdeployed at CINES is a digital preservation infrastructure that relies on mature, “ready-to-use” EUDATservices, which have been in production for several years, and provide data transferring functionalities. These services expose well-documented APIs, which were interfaced for dataset transferring and indexing purposes. These include:
- A B2SAFEnode to transfer datasets (digital documents, images, videos, etc.) ;
- A B2HANDLEPID allocation ;
- Data quality function modules such as integrity and antivirus control, file format validation and metadata validation;
- Post-processing modules (e.g OCR analysis, etc.) performed on CINES’s High Performance Computing (HPC) facilities ;
- Indexation and access interface. The post-processing results are indexed in full text in a search engine, allowing access to data and metadata with multi-criteria search capabilities, as well as harvesting in B2FIND;
- Long-term preservation performed on the CINES TDR, which has been awarded the Data Seal of Approval (the predecessor of the Core Trust Sealcertification) in 2010 and 2014, and complies with the FAIRprinciples.
