Hi, I stumbled upon DFDL searching about data archaeology - very interesting and relevant work! Is it already applied in practise for information preservation in libraries and archives? Unfortunately DFDL is not documented very well, compared to standards of W3C and similar institutions. Do you plan to set up a website with a more readable description of DFDL like other popular standards? json.org is one of the good examples because it describes the JSON standard easy to understand and with links to implementations. My second question is about the notation of DFDL. Has anyone tried to create a notation that is not based on XML? For instance Notation 3 is much more readable than RDF/XML and Backus-Naur-Form is more readable than a grammar formally defined in mathematical formulas. Especially if you describe non-XML formats it is a barrier to set up the whole XML framework stack in oder to use DFDL. I think that DFDL has strong potential but in the current form (both the way it is documented and its notation) it does not encourage potential users to adopt it.
