(via Sam) "Our main data store is Jena (http://jena.apache.org/), a graph-based database. Based on the concept of the Semantic Web, it allows you to store every kind of data in a completely flexible way, while still being capable of having a common structure in the data. Very handy. We run PostgreSQL as a supporting database." [1] -- Martin Böhringer, Co-Founder & CEO Hojoki
Thanks Martin for sharing (and kudos to you and all the Hojoki team. A great example of data integration breaking the barriers between the too many useful services out there). Paolo [1] http://www.quora.com/Hojoki-1/What-are-the-building-stones-of-Hojoki
