At the risk of pointing out the obvious, why not use what tomcat uses to store hierarchical data, XML? -- Charles Knell [EMAIL PROTECTED] - email

I have a structure like PC file system with meta data. There a folder objects and files objects of different types. Every object have data like permissions, date and author. And they have type-specific data fields like resolution (of an image type) or location (of an meeting type) or ingredients (of an recipe type). What is the best way to store that kind of data? What database is recommendable? What concepts of persistance? Or not using managed persistance and do it manually? Thanks for all ideas!
