YUP, HyperGraphDB supports JSON document storage (*), just like MongoDB, is transactional, unlike MongoDB which isn't, and the documents are actually graphs, therefore all interlinked through the graph structure transparently, so you can match up any structural patterns.

HyperGraphDB: Yeah, implementing a storage layer over a horizontally scalable key/value store is one approach that can be tried. There's a student that got most of the tests to pass with a Hazelcast based (non-transactional) storage so soon we could try some experiments with this implementation. Anyway, I'd be certainly interested to hear more if you pursue seriously any one of those projects :) Is Open DeepQA an existing project?

Jack Park: My own version resides here: http://debategraph.org/SolrSherlock and here: https://github.com/solrsherlock/
The project started life as a merge agent for topic maps, but it soon became clear that it needed a lot of the compute power of a DeepQA system, so it was expanded to serve other purposes, such as harvesting documents to build the topic map, and to participate in research, biomedical being of greatest interest to me.
Thus far, it has demonstrated its ability to detect simple merges; work is underway to begin the NLP project, which, I should add, will benefit from studying Disko, but is also benefiting from studying various OSS CG platforms such as Amine-Project at sourceforge.
I would like to think there will soon be many more Open DeepQA projects sprouting here and there.

HyperGraphDB: Nice! Yes, I agree, NLP projects will become more commonplace as foundation tools such as parsers and some sort of semantic analysis become available and easier to use.

This paper develops an extension to SPARQL supporting graph paths and "folders" (essentially subgraphs) called FPSPARQL, and then does some common practical queries comparing performance with SPARQL and HyperGraphDB circa 2010. It would be interesting to run their performance tests with the latest version of HyperGraphDB, in particular using the subgraph implementation.

A few Scala hacks to make it easier to work with the HyperGraphDB API: implicit graph object, handle dereferencing and "foreach" iterable traversals.

Ji Doc: The jars are where the error message says, it is my mistake, I need to set sbt up so they are in the eValhalla directory , because eclipse does not have access to root.

HyperGraphDB: Yeah, that makes sense. I thought you were running it as root since the current user shows as 'root'.

Ji Doc: I did run sbt as root , but I don't allow eclipse to run as root, which is what caused the issue, I believed sbt would use the eValhalla directory not the sbt cache in root.
