Scaling Islandora
0 likes•795 views
The document outlines challenges with an inactive project that struggles with performance due to triplestore issues and incomplete SPARQL implementation. It proposes strategies for improving scalability and performance through media streaming, load balancing, and caching configurations, while also detailing the need for developing a scalable repository that can handle more concurrent users and objects. Continued integration work with Fedora 4 is also noted as part of the solution.
