-Some elements of [HTML5](http://www.whatwg.org/specs/web-apps/current-work/multipage/) can be safely supported by ikiwiki. There are [several differences between HTML4 and HTMl5](http://www.w3.org/TR/html5-diff/). Unsupported new elements _should degrade gracefully_.

-However as an [early adopter](http://en.wikipedia.org/wiki/Early_adopter) I would like to start using HTML5 as much as possible. The more pragmatic solution would be to use elements supported by the browsers of your readership I guess. I'm following other early adopters like [Anne](http://annevankesteren.nl/) for clues on how to proceed.
+>> TODO Still need to merge origin/html with my html5 branch.
-* [Initial patch](http://git.webconverger.org/?p=ikiwiki;a=commit;h=2e2bb3f74f5000b1269142d6f9bdf1bcb4075ca4)
+* [HTML5 branch](http://git.webconverger.org/?p=ikiwiki;h=refs/heads/html5)
+* [test ikiwiki instance with HTML5 templates](http://h.dabase.com/html5/)
-> I can't figure out how to pull from this repository.

+# HTML5 Validation and t/html.t
-I'm unsure how to turn off the test validation by the very old [wdg-html-validator](http://packages.qa.debian.org/w/wdg-html-validator.html). So I have been unable to test my initial patches as I can't build ikiwiki. I would like to know how to edit the rules/Makefile to temporarily disable this.
+[validator.nu](http://validator.nu/) is the authorative HTML5 validator,
+however it is almost impossible to sanely introduce as a build dependency
+because of its insane Java requirements. :( I test locally via
+[cURL](http://wiki.whatwg.org/wiki/IDE), though Debian packages cannot be built
+with a network dependency.
-> Don't run ¨make test" ... --[[Joey]]
->> I don't quite grok debhelper7 [rules](http://git.ikiwiki.info/?p=ikiwiki;a=blob;f=debian/rules).
+In the future, hopefully ikiwiki can test for valid HTML5 using [Relax NG
+schema](http://syntax.whattf.org/) using a Debian package tool
+[rnv](http://packages.qa.debian.org/r/rnv.html).
->>> Well, ok :-) `rm t/html.t` or, add an empty `override_dh_auto_test` rule.

-[validator.nu](http://validator.nu/) incidentally is **the** HTML5 validator, however it is almost impossible to sanely introduce as a build dependency because of its insane Java requirements. :( I test locally via [cURL](http://wiki.whatwg.org/wiki/IDE), though Debian packages cannot be built with a network dependency.
+## Time element
-# Notes
+The [time element](http://www.whatwg.org/specs/web-apps/current-work/multipage/text-level-semantics.html#the-time-element) ideally needs the datatime= attribute set by a template variable with what [HTML5 defines as a valid datetime string](http://www.whatwg.org/specs/web-apps/current-work/multipage/infrastructure.html#valid-global-date-and-time-string).
-* the [time element](http://www.whatwg.org/specs/web-apps/current-work/multipage/text-level-semantics.html#the-time-element) ideally needs the datatime= attribute set with iso8601 time
-* I suspect the migration to the new semantic elements of HTML5 like article, header & footer to take some time, due to browser support. Though they sure make the template code look much nicer.
-* `<br>` and too many `<div>`s usually indicates poor semantics.
- > YMMV, but I tend to find that kind of concern counterproductive.

+As a workaround I use in my setup file:
-* Many of the header `<span>`s should be proper [header elements](http://www.whatwg.org/specs/web-apps/current-work/multipage/semantics.html#the-h1,-h2,-h3,-h4,-h5,-and-h6-elements)
+ timeformat => '%Y-%m-%d',

> See [[todo/Option_to_make_title_an_h1__63__]] for why not. --[[Joey]]
+
+The [header element](http://www.whatwg.org/specs/web-apps/current-work/multipage/semantics.html#the-header-element) requires a h1-h6 child, in order to [validate](http://validator.nu/). Hence in my [html5 page templates](http://git.webconverger.org/?p=ikiwiki;a=tree;f=templates;hb=refs/heads/html5), I've marked up page title with a h1.
