LoCloud D2.3: Modified MoRe prototype

This deliverable presents the modified cloud MoRe prototype which has been implemented according to the specifications layed out in the D2.1 deliverable. The cloud prototype has been implemented based on a pluggable storage architecture where multiple technologies can be combined in order to extend the system. The Apache Cassandra framework has been used as the prototype’s storage layer with a content model inspired by the previous MoRe version (a content model that supports coxmplex digital objects with versionable datastreams). The core services implementation of the MoRe prototype are presented with the most significant to be the messaging service that acts as a glue for the rest of the core services. Finally, the scalability architecture and capabilities are presented in detail.
