Follow-up on discussion with respect to same origin: Fully Qualified Domain Name or Private Domain

AndersonQuach: Sigborn preferring Private Domain
... Jonas prefers the FQDN

Zhiheng: Okay with Private Domain, no strong preference.

TonyG: I certainly like Private Domain.

AndersonQuach: We agree to Private Domain, great.

move to agenda 5.

Performance name space under window" taken up

JamesSimonsen: Any precedence with adding objects under window.

TonyG: Yes, HTML5 interfaces. There is a precendence.
... should we make performance object make it replaceable.
... aburden to check if the property can be overridden.

Zhiheng: it's a global space problem.

TonyG: Let's try it, and the first site compat bug we'll remove the attribute.

JasonSobel: Do you have an tool to check for API usage given privacy concern?

JamesSimonsen: have a tool to check API usage on the web

AndersonQuach: I like the idea of measuring the risk.

2. Test submission process for Navigation Timing.

<biesi> sorry for being late

np

<Zhiheng> public-html-testsuite@w3.org

AndersonQuach: Recommend three phases: a proposed, submitted and approved.

Zhiheng: can we get best practice info from other working groups?

AndersonQuach: will follow-up with plh.
... Let's follow-up offline with some existing HTML test cases to pattern off of.

Resource Timing and User Timing.

AndersonQuach: two proposals: i. Resource Collector, ii. static getter via the DOM

JasonSobel: Looked over proposals during the week, the proposal Anderson sent out that it was more intuitive to use.
... Nice to have to filter to specific timing for a specific resource.

AndersonQuach: Great I'll follow-up offline with an interface with by id or by url.

TonyG: Question, why a list, or what is reserved_htc and other?

AndersonQuach: List so that in the processing of onbuffer full we do not lose events.

sub-class link and rel?

TonyG: how about link rel=stylesheet,imports,prefetch

NicJansma: Being clear of the origin and mime type we got back.
... initial tag where the download occured, i agree we could sub-class css, font, image. Either specifiic or higher-level.

TonyG: Looks like a good initial list, let's figure out the main interface and continue to add to the existing list.
