We’re happy to announce the public release of part of Clepsydra, data aggregation and enrichment framework. It is released under the Apache Licence, Version 2.0.
Clepsydra is a flexible and scalable system for aggregation, processing and provisioning of data from heterogeneous sources. It was designed and developed to be a basis for services focused on aggregation and enrichment of data, e.g. metadata describing on-line collections of cultural heritage objects from Polish memory institutions. The first production deployment of this system is the PIONIER Network Digital Libraries Federation. Clepsydra is developed as a part of PSNC activities in the SYNAT project.
This first release of Clepsydra contains one component, Clepsydra Storage, which main aim is to serve as a flexible and scalable service allowing storing and accessing large amounts of heterogeneous data.
Installation instruction, documentation and source code for Clepsydra Storage module can be found here.
