A Document 2.0 world needs standards. In our past/current (Document 1.0) world, documents were mainly stored in their own proprietary formats. In Document 2.0, documents are increasingly stored in open, interchangeable formats — to everyone's benefit. I am not claiming that Ismael's Document Sharing problems will disappear overnight, but the appearance of a few, and hopefully now a single XML-based standard for document sharing helps move us in the right direction.

This will greatly increase the Entreprise Adoption of Document 2.0 and Office 2.0 technologies. Since documents are increasingly distributed, collaborative, "mash-ups" of information stored in various locations, interoperability and interchange at a very granular level becomes vital.

But this evolution should continue. Being able to identify a table and an individual cell in a document is a definite need, which ODF can handle nicely, but what about extracting documents from unstructured documents such as resumes, letters or contracts? Over time, the document should become semantic — capable of storing semantic information (or even re-creating that structure on the fly), besides structural and layout information.
