Novell talks about the OpenXML support in OpenOffice
There's a little blurb up on the Novell PR blog talking a bit more about the OpenXML translator release: https://www.novell.com/prblogs/?p=299
Novell is cooperating with Microsoft and others on an open source project to create the bi-directional translator for documents, spreadsheets and presentations. We're still hard at it on the translator project, working to extend the interoperability to spreadsheets and presentations.
