Subject: raw delta export from the Google Wave service
To: wave-p...@googlegroups.com, wave...@incubator.apache.org


The Google Wave team would like to announce a wave data export option
intended to support importing wave data from wave.google.com to your
own wave server.

We have added an option to the ROBOT_FETCH_WAVE method in the Wave
Data API to get the raw deltas from a wavelet. These raw deltas
provide the wave's complete history. We expect there will be a little
work to turn them into a form suitable for any particular WIAB
instance. The raw deltas export and some important caveats about how
it works are explained here:
http://www.waveprotocol.org/wave-apis/google-wave-data-api/raw-deltas-export

The wave Data API
(http://www.waveprotocol.org/wave-apis/google-wave-data-api) gives you
programmatic access to your data in the Google Wave service. You
authenticate using OAuth and can use the Java or Python robot client
libraries to access the methods, or access the HTTP protocol directly
(http://www.waveprotocol.org/wave-apis/google-wave-data-api/http-protocol).

Please try out the raw deltas export. We are looking for help with
important work that remains to be done in Wave in a Box. It will be
good to implement the raw deltas export option in WIAB's Data API, for
testing and for export from one WIAB instance to another. More
importantly, import logic is needed to put deltas exported by the Data
API into the WIAB wave store. The deltas are exported "as-is",
including @googlewave.com addresses and ids. Work required to import
includes:

- Rewrite wave ids (including in links, etc) and participant addresses
to your own domain

- Migrate legacy cruft away from Google Wave's internal representation
(the Google Wave team will do this bit)

- Sign the deltas

- (Optional?) Build WIAB UI to serve a web page to users for them to
OAuth authorize WIAB to download their waves
