It is likely to be a more traditional approach, with automation of the mapping for simple cases. Certainly an approach like Glorp reflects my biases :-)

While I'm not familiar with REServe, I don't see as much value in trying to do an OODB-like approach layered onto relational. If people can use an OODB, then they are better off using one directly. One of the motivations for using a relational databases is that there are other things accessing the data that want it in relational form. This is less likely to be doable using something that maps the objects onto its own opaque relational schema.

An example of the sort of things I have been thinking of can be seen in the GlorpActiveRecord packages in the Cincom Public Repository. I also talked about that at the Cincom User Conference in December in Frankfurt. It's sketchy, and things always change, but it's a start.
