Subject: Setting up a recommender

Also a question about user history.

I was planning to write these into separate directories so Solr could fetch them from different sources but it occurs to me that it would be better to join A and B by user ID and output a doc per user ID with three fields, id, A item history, and B item history. Other fields could be added for users metadata.

Sound correct? This is what I'll do unless someone stops me.

Once you have a sample or example of what you think the
"log file" version will look like, can you post it? It would be great to have example lines for two actions with or without the same item IDs. I'll make sure we can digest it.

I thought more about the ingest part and I don't think the one-item-space is actually a problem. It just means one item dictionary. A and B will have the right content, all I have to do is make sure the right ranks are input to the MM,
Transpose, and RSJ. This in turn is only one extra count of the # of items in A's item space. This should be a very easy change If my thinking is correct.

I am working on this issue now.

The current state is that I can bring in a bunch of track names and links
to artist names and so on.  This would provide the basic set of items
(artists, genres, tracks and tags).

There is a hitch in bringing in the data needed to generate the logs since
that part of MB is not Apache compatible.  I am working on that issue.

Technically, the data is in a massively normalized relational form right
now, but it isn't terribly hard to denormalize into a form that we need.
