In cooperation with IVA members and partners, Microsoft put Open
XML to the test in real-world business scenarios at the IVA Open
XML Interoperability Lab. Office Open XML (Open XML) is an
international, open standard for word-processing documents,
presentations, and spreadsheets that can be freely implemented by
multiple applications on multiple platforms.
The solutions tested during the lab demonstrated the
interoperability of Open XML files across a wide range of
applications on mixed platforms. Open XML lets the data inside of
documents be tagged for queries; at the same time, it makes them
compatible and editable by many applications across operating
systems and platforms. In this collection of use cases, we
demonstrated these aspects of Open XML documents.

Lab Scenarios
The IVA tested multiple client applications running on different
platforms to demonstrate the interoperability of Open XML through
translation to other formats like Open Document Format, or ODF.
The IVA tested document interoperability on mobile devices and
other client applications that open and preview files. The IVA used
multiple desktop and mobile operating systems to preview Open XML
documents, spreadsheets, and presentations before opening them in a
variety of applications that support Open XML. Dynamic previews of
Open XML files also were tested on multiple browsers with Web-based
e-mail.
