Hi Seth, Maybe I didn't make myself clear enough or maybe I don't understand what you mean :) But your example code suggests referring to an actual path (file:///C:/wherefor/whatever/) on a user's machine. Is that what you meant? I can't do that since I don't know what that path is - only the user installing my package knows where they installed the application that my package is an extension for. I still need to refer to files that are part of that application that I don't know the installation path for - all I can say is that those files have a particular path *relative* to whatever the installation path is: I know what the relative path is - I don't know what it's relative *to* except logically as "wherever you installed application X or Y". So my problem is: how do I describe a path relative to a base path that can be described only logically but not as a specific path? Sorry if I misunderstood your suggestion though - I'm still new at this. If I did misunderstand could you try to explain a bit more? Thanks!

Essentially they would still be relative paths - but relative to the "installation path" of the application my package is an extension for. The actual installation path will be different for different users; still that installation path will also be the target installation path for my package, so (more or less): a path relative to the distribution == a path relative to the installed package AND a path relative to the installed package == a path relative to the user's application path. >>I'm not sure if I would need to define a base path for required files in this case (strictly speaking they can't be relative to the distribution of my package since they're not included - but *will* be relative to the package once installed correctly). >> >>A related question is: is there a way to self-reference an RDF file, so that (for instance) I could use an RDF statement *within* the file to state something like: all xlink:hrefs in this file are relative to [some logical description of "application installation path"]? >> >>Suggestions, anyone? >> >>. >> >> > -- Marjolein Katsma HomeSite Help - http://hshelp.com/ Java Woman - http://javawoman.com
