That's probably it -- can you provide any errors? it is almost surely something to do with paths, which I might be able to fix quickly. core and examples must build for this to work. > On another note: Has you out anythought to implementing TASTE for a)google > App Engine for Java and b) using simple db has the database App Engine is Python-only for the moment and no I would not seriously consider reimplementing in Python myself. But it is to support Java shortly. In that case, yes perhaps. I had already created a machine image (AMI) for Amazon's EC2 which would load data from S3, process all recommendations, and shut down. This sort of thing could be replicated on App Engine; it is a nice model. However, even better, Amazon just announced an easy framework for MapReduce (Hadoop) on EC2. On top of my to-do list is to put together the steps to run recommenders this way. The Hadoop bindings are already written; should be easy. This will be an even better model that the App Engine / EC2 model above. So I suppose I'd focus on this mostly. SimpleDB, Amazon's DB? I wouldn't object to a DataModel based on it. My concern is that recommenders are so data-intensive and access data so frequently that even a local database is quite slow -- let alone a distributed database like SimpleDB. I sense it is not cut out for this use case.
