Hi all, I have produced a revised Internet draft, http://www.ietf.org/internet-drafts/draft-miller-media-type-cellml-01.txt, following the earlier draft for the registration of application/cellml+xml reviewed on this list. This draft replaces the MIME type being registered, application/cellml+xml, with two MIME types application/cellml-1.0+xml and application/cellml-1.1+xml, based on the recommendations of several ietf-types list members. While CellML versions are not substantially different from each other in terms of the XML element localNames, the changes between 1.0 and 1.1(and likely any future versions) will make backwards compatibility for impossible for most, if not all, CellML processing tools. As such, a new media type for each version is justified. Similarly, the version parameter and the section on determining the version from the XML has been dropped. Both versions of the CellML specification are now referenced as normative references. There was a recommendation on the list that a file extension other than .xml be used for CellML files. This has been discussed with the CellML community on the CellML mailing list, and at the last (and earlier) CellML meetings. However, the consensus was that we should keep the convention of using .xml, as this is currently in wide use. A lot of CellML content currently being served is done by scripts, which can arbitrarily set the MIME type. Most other CellML content served over HTTP would be in its own directory, and so mechanisms like .htaccess(or content based type determination) supported by most popular webservers will be available. In addition, it is probably better that existing software be able to at least determine that it is an XML file, and so using an XML extension will result in text/xml or application/xml. As such, the section on File extension(s) has been left unchanged. Due to the fact that the names of MIME types have changed, I am restarting the two-week review period from today. If there are no new objections, I will submit the document for IESG approval on the 25th April, 2006. Please Note: cellml-discussion@cellml.org is a public list for the CellML community, but only accepts postings from list members. I am on the cellml-types mailing list, and will forward any responses posted there to the cellml-discussion list.
