Hi MarkFo, All,

MarkFo suggested [1] the following feature to the Presentation API I'd like to bring to the mailing list for further discussion:


Allow page to designate a default presentation URL

Some user agents may wish to allow the user to initiate presentation from the browser instead of by triggering it via an action on the page. This is analogous to choosing "Print" from the browser menu instead of calling window.print().

In this scenario, the page should be able to designate a default presentation URL that will be shown when the user initiates presentation via the browser.



Here's how I (puts hat off) see this could work:

* The page at https://example.org/ defines its default presentation URL by providing a hint to the UA, for example:

<link rel="presentation" href="show.html">
* The user initiates the presentation from the UA's user interface (e.g. chooses File > Present, taps a dedicated button -- an implementation detail).

* The UA behaves as if startSession("https://example.org/show.html") was invoked.

That's omitting a lot of details, for example, how this ties into the event lifecycle.

In addition to the print use case MarkFo mentions above, this is similar to the way how the W3C Manifest spec [2] enables the "add to homescreen" flow.

[hat on]

All - please let us know if you have comments or feedback on the proposal.

MarkFo - what is the relationship between [1] and [3]?
