Lucene Layer Cake

With a proposal for Pig (a query language interface for very large datasets) to go into the Apache Incubator, it looks like the Lucene family is growing once more. With so many members it gets harder to track the inter-project dependencies, so I created a quick family portrait.

Update: not long after writing this I noticed this patch to run Lucene on Hbase (a part of Hadoop) - so now my diagram's wrong. It was a bit of an oversimplification anyway - it's meant to give a rough idea of the building blocks of Lucene.
