Hi Robert, I'm glad to hear that you are interested in pushing Betwixt on and embrace new ideas. But before I start to come up with some of my ideas I would like to know what your preferences are.
The ID/IDREFS is a good way to support references, when your data is kept inside one single XML file. As long as you can make sure, that the beans implement an equals method, it should be quite simple to provide an support for the ID/IDREF stuff. What I was talking about in my previous mail was the ability to support a kind of XLink, which supports references between different XML documents. Until now I am not really sure, if this is a subject to Betwixt at all, because you will have to provide extra information or special objects for those references. At the moment I did not think about how to keep this flexible, if it is possible at all. But anyway I would like to use Betwixt in a more flexible way (e.g. having own XMLBeanInfos for some Beans). Sadly my interest in supporting ID/IDREF is small, because it doesn't help me on with my problem. In fact using ID/IDREF is just a way to keep your XML files smaller. But on the other hand, if you are interested in making the way beans are written and read more flexible I would like to support you. For example what is it about the .betwixt files? I could not further information about them. BTW: I have posted this message to the user and the dev mailing list, because I think we should move this topic to the dev list. - Harald > -----Ursprüngliche Nachricht----- > Von: robert burrell donkin > [mailto:robertburrelldonkin@;blueyonder.co.uk] > Gesendet: Montag, 11.
