RE: Updated Presentation API WebIDL - call for review

Hi Anton and Wesley,

 

I would prefer to have some spec for interoperability among browsers.  Do we have any issue with PeerConnection?  I assume it works without a server within the same local network.

 

Best Regards,

Dong-Young Lee

Hi Wesley,

 

the idea is to leave this details out of the spec for the browser to implement. This may leave different browsers supporting different protocols and second UAs but should be less of a problem for the web developers since the code on the sender is the same.

 

Thanks,

Anton.

Just glancing at this briefly, there's still nothing in the spec to describe how we would actually facilitate communication between two different UA's.

i.e. UA1 calls postMessage() -> Magic happens -> UA2 receives onMessage

We'd really like to avoid that sort of magic, and there are already specs (as I mentioned earlier, PeerConnection?) that do handle it. In the same way, if we're tackling two UA systems here, I think we also need to define how discovery and the initial setup of a connection between two UA's is handled. I'd like to avoid a situation where that communication has to be defined differently for each different type of device.

I like the idea of using this as a way to make Network Discovery work, but I think we'd be hesitant about implementing anything until there were solutions to those problems.

Hi All,

As a group, we’ve now mulled over the design of the revised Presentation API by looking at the use cases, requirements, and concrete usage examples.

As the concrete next step, we’ve drafted the WebIDL for the updated Presentation API, ready for your review at:

  https://www.w3.org/community/webscreens/wiki/API_Discussion#WebIDL

All - please review the WebIDL and chime in on the list if you have any questions or concerns, big or small. Also, if you’re happy with the direction, positive signals are also encouraged, even if just +1s. As usual, silence is considered consent.

Before we start land changes to the spec itself, we want to ensure we’re aligned, so your feedback at this stage is much appreciated.

Thanks,

-Anssi
