Augmenting ODF with OOXML elements
Rick Jelliffe One possibility for the co-existence that hadn’t grabbed my attention until today has probably been obvious to everyone else: when converting from OOXML to ODF just embed OOXML-namespaced elements inside the ODF where there is no direct equivalent. This allows good round-tripping, doesn’t require ODF to be extended with legacy Office-isms, allows developers who want to support more than the ODF base to do so, gives better fidelity for Office users ... ODF already allows foreign namespace elements. I guess what ODF would need to support this well would be a mechanism to say “This kind of foreign element should be stripped out when its context changes, but round-tripped otherwise.”
You know, that last idea could be handy for AtomPub too...
