Re: CFC: Change of Content SC

Gregg,
The continual changes concern has been raised and discussed (https://www.w3.org/2017/05/30-ag-minutes.html#item04) and while we don’t believe that we have the perfect solution right now we feel like it is worth getting this SC into the Editor’s draft so we can get additional comments.

Regarding your other question, this is not just in response to a user action. A news site might add articles on some interval and that is in response to time or external events, and in that situation the site would need to provide notification that the content was changed.

Thanks,
AWK

Subject: Re: CFC: Change of Content SC

Looks interesting.

But before we reach consensus on this    -  a couple questions and suggestion (depending on answer to question)
.

?? Do we have techniques for doing this?

For example in a game or simulation - there will continual changes of content.   There is no exception for this  — so is there a technique that should be used in these situations  to indicate that there are continuously changing content?

?? Or is this ONLY supposed to apply to content that changes in response to a user action.

That would make sense - but the current language does not say this

current language

Programmatic notification is provided for each change of content that indicates a user action was taken or that conveys information, unless one or more of the following is true

Perhaps something like


Programmatic notification is provided for each change of content that RESULTS FROM A USER ACTION AND THAT indicates a user action was taken or that conveys information, unless one or more of the following is true:

??  If you DON’T mean changes due to user action — then for dynamic content (constantly changing) content is a simple notice someplace that says that the page has continually changing content sufficient?  or would the page need to stream a constant flow of notifications through some mechanism that is supported by AT?
