I've developed an ORM RESTful JSON based framework, using SQlite3 for its database persistence.
It's not so complete than Bold or OPF, of course (no UML nor OCL), but it works, and is tested with Delphi 7 up to Delphi 2010. And it's still maintained, and will be forever, because it's free and opensource.
You've interesting features like integrated User Interface generation and i18n, reporting and export to PDF, client/server services, integrated unit testing. It uses JSON for data transmission, and a RESTful architecture over in-process communication, windows GDI messages, named pipes, or HTTP/1.1. So it could be used for developing AJAX applications.
This framework integrates gracefully with our SynProject tool, which creates documentation from the source code, with nice graphs and complete document traceability (it has been used to fulfill IEC 62304 requirements for a medical SW we wrote with this framework). So you don't have UML, but you have documentation and diagrams available at hand.
If you're interested in ORM and Delphi, you're welcome joining the adventure of Open Source!
