Dear Macro, Thanks a lot! I've updated the code in the following ways: 1. Add the support for indexing literals without datatypes, i.e. the support for b.) in the previous mails. You can find the demostrations in the test [1], and in the example code [2]. 2. Add a test [3] for a file based TDB Dataset with the spatial index. Actually, jena-spatial is suitable for any types of Dataset, including in-memory ones, file based ones (such as TDB), or something else. Please check "JenaSpatialExample1.joinDataset()" in the example code [2], which shows how to add the spatial indexing support for a base Dataset.

I'm very grateful to your valuable feedbacks!
