But when you're writing the DTD, how do you know what is "content" and what is "metadata"? For example, if you have a genealogy DTD, and you're representing things like: Biological father Biological mother Location where birth certificate is recorded Place of birth Date of birth ...and so on. Which are content, and which are metadata? It seems to me that there isn't any inherent distinction, but rather an arbitrary distinction is imposed by the designer at the time the DTD is written. > It is much >easier to process (and eventually to ignore or filter, e.g. for >displaying/editing content) additional information that is encoded in a >different way than the document's content. The only problem is that you are more or less locked in to the designer's original (arbitrary) designations regarding what's content and what's metadata. If you want to come along after the fact and do some ad hoc processing (supposedly one of the advantages of XML), you may very well find that what's content and metadata for you isn't quite the same as what the original designer thought of as content and metadata. At that point, the content/metadata distinction becomes a liability, rather than an asset. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Mark Nutter, <mnutter@f...> Internet Applications Developer FORE Systems Some people are atheists 'til the day they die. xml-dev: A list for W3C XML Developers.
