Description
Developed in the context of the 2017-2020 Swiss national program "Scientific information: Access, processing and safeguarding", the DLCM solution (dlcm.ch) consists of an open and modular architecture for long-term preservation of research data, compliant with the OAIS standard (ISO 14721). The independent modules, once deployed in the cloud, offer a range of services that allow researchers to prepare their data for preservation, namely: to submit them with a pre-ingest step followed by ingest (submission package), to store them physically (archival package), to index the metadata (METS container with PREMIS and DataCite fields) and to be able to access them according to specific rights (distribution package). This set of services, available via RESTful APIs, guarantees on the one hand the implementation of best practices in the domain: virus detection, format detection, checksum calculation, integrity check, replication, etc., and on the other hand a tight integration to Laboratory Information Management Systems (LIMS). A preservation planning module (preservation-centric workflows) handles replication and synchronization of data, stored in different data centres, with the possibility to be interfaced to the LOCKSS technology, which is based on the Byzantine Generals' Problem, with 3n+1 geographically-distant storage nodes, allowing to tolerate up to n faults.
