Dion Hinchcliffe has posted a lengthy discussion on the future of Open Data and the Open Web.  He identifies three Open Web methods for accessing and working with Open Data; WOA, API's and Linked Data.  These methods are discussed in the context of SOA and the re-engineering of enterprise business systems.  Great stuff.  Dion also provides an excellent chart describing his vision of how these things fit together. Excerpt: "Open data holds up the promise of instant connectivity between arbitrary numbers of ad hoc partners while at the same time reducing integration costs, improving transparency, harnessing external innovation, and even (perhaps especially) creating entirely new and significant business models. I sometimes refer to these as "open supply chains", and the term is highly descriptive when it comes to the potential for open data models to make cloud computing safe and interoperable, help journalists to do their jobs better, or create multi-million dollar new lines of business, such as Amazon's well-known Web Services division."

Dion Hinchcliffe has an excellent article casting Google Wave as an Enterprise game-changer. He walks through Wave first, and then through some important enterprise features: ".....to fully understand Google Wave, one should appreciate the separation of concerns between the product Google is offering and the protocols and technologies behind it, which are open to the Web community: Google Wave has three layers: the product, the platform, and the protocol: The Google Wave product (available as a developer preview) is the web application people will use to access and edit waves. It's an HTML 5 app, built on Google Web Toolkit. It includes a rich text editor and other functions like desktop drag-and-drop (which, for example, lets you drag a set of photos right into a wave). Google Wave can also be considered a platform with a rich set of open APIs that allow developers to embed waves in other web services, and to build new extensions that work inside waves. The Google Wave protocol is the underlying format for storing and the means of sharing waves, and includes the "live" concurrency control, which allows edits to be reflected instantly across users and services. The protocol is designed for open federation, such that anyone's Wave services can interoperate with each other and with the Google Wave service. To encourage adoption of the protocol, we intend to open source the code behind Google Wave.
