1 - Description:

 

A standardized way to scrape data from html elements for powering widgets with progressive enhancement. For example, a standard html select could be turned into a standardized data object that could be used to populate a slider, date picker, combobox, etc. Or an html table could be transformed into a chart or grid by parsing out the data.

 

A very basic version of the idea of grabbing data from an html table is used here for visualizations:

A more robust systemfrom Dojo is probably a closer starting point:

6 - Open issues being discussed

 

(Use this area to place things that we're hashing out like featuresand options we're not sure we should include, questions about how this fits into UI and relates to other widgets and utilities, known problems, whether features should be broken across multiple releases, etc.)
