Hi everyone, My original plan to be at the meeting has been changed somewhat. My baby son was born on the 6th January, a few weeks earlier than planned. He's doing brilliantly, but I'll be at home with my new family on the day. Having said that, a few comments inline.

Specifically, this means that I've been attempting to construct the spec as a series of commands and parameters, leaving encoding and transport undefined. There will be a non-normative mapping of these commands to HTTP and JSON included in the spec. Other encodings and transport mechanisms (protobufs over scope, some form of RPC, using Thrift, etc.) should not be precluded. I imagine that this flexibility will be most useful for browsers on mobile devices. In addition, the spec only talks about the end points, assuming any additional architectural tiers (such as the Selenium Grid) are transparent and conform to the spec. Finally, I strongly believe that the spec needs to support both in-process (that is JS bindings) and out of process (similar to the existing remote webdriver) implementations, and for the user-facing API to be written from the point of view of the person using the bindings (as the current webdriver api is). This is because our experience over many years suggests that test authors want to use the language being used to write the app under test, and these will probably be the largest group of consumers of this spec once complete. > * Does the outline of the draft spec look alright?

At the first meeting, we discussed writing tests in JS or Python. I'm still happy with either choice, but Python is my preference. David Burns has already started looking at some of this work. It would make most sense for the tests to be added as each section of the spec is committed in order to ensure that everything is as close as possible to being in sync. > * Are there other organizations we wish to bring to the table > for the future work? > Apple seems like the most obvious missing face at the table. > We'll have lunch together during the day, and aim for ending the > meeting at 16:30.

I'll be discussing the agenda and the spec with David before the meeting, so he should know what I do. In addition, two of the Google webdriver team, Eran Messeri and Daniel Wagner-Hall will be on hand. Both of them are extremely familiar with the work that's already been done and the planned future direction of the spec and the project. > If you get lost, can't find the venue, or for any other reason > need to get in contact with me, feel free to call me at > (+47) 97723641 or ping me at IRC (wilhelm @ freenode and w3.org). > > If you have any suggested additions or changes to the agenda, > feel free to either prod me directly or send a reply to this list. Looks excellent to me. Thank you! Simon
