The document discusses Open Document Format (ODF) which aims to make office documents more accessible and interoperable by being based on open standards like XML, ZIP, and CSS. It describes how ODF files can be programmatically processed at different levels of abstraction from direct XML to object models. Frameworks like odf4j and AODL provide ODF support for Java and .NET respectively, hiding some of the XML complexity and exposing ODF semantics. Future work areas include harmonizing ODF toolkits and extending ODF through new metadata mechanisms.
