The plugins site is currently in development.
We've been looking to provide a higher-quality, spam-free experience at the plugins site for some time, and a major error on our part forced us to shut down the current site before we could put the new one in place. We are developing a new site, and you can follow along with its development on GitHub. For more information about this transition, including steps you can take as a plugin author to prepare, please read our post about what's going on.
Metadata 2.1
Adds support for HTML5 data-* attributes. Usage is:
<p id="one" class="some_class" data-item_id="1" data-item_label="Label">This is a p</p>;
$.metadata.setType("html5")
$("#one").metadata().item_id == 1;
$("#one").metadata().item_label == "Label";
