The term DataPortability refers to something important, but doesn’t refer to it very well. A new video does a good job of explaining the problem that the DataPortability Workgroup (DPW) exists to address.
The video is by Michael Pick of Smashcut Media. I found it via Read-Write Web. There are some interesting comments arising from Marshall Kirkpatrick’s post there: I now have more idea about what it means to join the DPW.
I think that the video is better as a statement of the problem being addressed than as a description of DataPortability. That’s less of a criticism of the video than a request for a sequel.
