People at the talk had some interesting ideas about how they might use SDOs to solve problems - if you did go home and try them out, I'd be pleased to hear how you got on, and any opinions you'd like to share, positive or negative. I had great time at php|tek, especially hearing about so many diverse areas that people are working in - everyone seems to have something special about their requirements or their environment. I also liked watching the alligators in the lake, and taking my morning swim in the open air (not in the lake).
In recent months we've had some requests from developers who would like to contribute to the SDO for PHP project. We recently added a Contributor License Agreement file to the project, so we can now welcome any developer who would like to be involved. There are instructions in the file about where to send it. Our CLA is based on the Apache CLA, and does not ask you assign the rights to your code, or inhibit you from using it for any other purpose. It simply serves to state the the code is yours to give, and that you do not impose any restrictions on its use.
