CarrotsSpacing: 10cm. If you’re super keen to have a play with the new dataset property but disappointed that it hasn’t been implemented, fear not!, for there is a light at the end of the tunnel. That way your data is search engine indexed, accessible to machines in a readable format, etc. I’m all for adding HTML5 attributes for things like click tracking. Unfortunately, the new dataset property has not yet been implemented in any browser, so in the meantime it’s best to use getAttribute and setAttribute as demonstrated earlier. In HTML5, it has data-* attribute which is used to store custom data with an HTML element. Feedback is, of course, welcome. If you are planning to have data understood by the search engines, you could use microdata which is more semantic. The data-* certainly will be useful, but that carrot example isn’t a great example. Every HTML element may have any number of custom data attributes specified, with any value. I like it. I am newbie in here, but I get understand about HTML5 attribute from your explanation. HTML5 data attributes allow developers to add data to an element. s there any guideline for consuming RDFa in XHTML5? @Scott – the namespacing isn’t to create “site-specific” data attributes, but in-application namespacing. (Something like this). You could use getAttribute() with their full HTML name to read them, but the standard defines a simpler way: a DOMStringMap you can read out via a dataset property. Doing `plant.dataset.leaves = null` in Chrome it does not remove the attribute. As far as the browser and indeed the website’s end user are concerned, this data does not exist. isn’t using/storing data values in html markup a bad design? Just trying to guess what the version/script is could potentially break a ton of sites, so I would prefer to keep the script replacement feature an opt-in mechanism.
