Subject: Re: [oiic-formation-discuss] Proposed Use case -- Interoperability in vertical and horizontal ODF markets

This has roots in the former OpenDocument Foundation's failed "da Vinci" project, which was an attempt to write an ODF plugin for MS Word. They planned on storing proprietary MS Office formats as opaque markup associated with the ODF content. So, if Word had a list style that could not be represented perfectly in ODF, then they would make a best-fit mapping to ODF and then also store the original Word list definition as essentially a blob in a foreign namespace. So this information would be unusable to anyone else in the word, except to the da Vinci plugin, who could look at it when the document returned into MS Word.
