GWDG CDSTAR

GWDG CDSTAR (Common Data Storage ARchitecture) is a head-less data repository and framework for research data management applications. The goal is to provide a rich set of common functionality (scalable storage, publishing, archiving, metadata annotations, access management and search) as a web-service for other applications to build upon, and to simplify the rapid development of highly customized tools and workflows for data-heavy research applications.

CDSTAR is developed at GWDG as open-source (apache licence 2.0) and offered to our customers as a fully managed service (including storage, backup and long-term archiving), or as self-hosted software solution for individual use cases. Please contact support for details.

Getting Stated

Source code, binary builds and documentation for recent CDSTAR versions (3.x) can be found at cdstar.gwdg.de. We provide a public API demo (username: test, password:test) for quick tests. Please note that the demo instance is wiped clean at least once a day. You can also run a local or self-hosted instance as described here, or contact support for a hosted instance.

Client Libraries

All functionality is provided as a simple language-independent web API, so any generic HTTP client library or even curl would be suitable to integrate CDSTAR with new or existing applications. Specialized client libraries and command-line tools are available for python3 (see pycdstar3) and Java. Other language integrations may also be available by third-party.

Legacy Versions

The legacy version of CDSTAR (version 2.x) is still supported for existing projects. Source code is available on request. Documentation can be found here.
