I need to adapt a plone portal do include a customized NEW item that would allow users to upload files and fill in a form with informations about the file. Besides the usual 'description' field already available, the form would have more 5-7 fields describing the file (author, colaborator, keywords, title, description...). The view of this item should render all the information filled by the user, a link to the file, and should also have a link to the RDF (its a kind of xml) format in another page inside the portal. I would also need a doc with the instructions of how this is done, so I could make minor changes later if necessary. Thanks.
