W3C DigitalDataLayer Report 2013.12.10

v1.0 of Customer Experience Digital Data Layer Specification (not a W3C standard). Original available here: http://www.w3.org/2013/12/ceddl-201312 . The structured data layer is a way to separate out information collected for measurement and marketing (such as analytics tags) within digital content. The concept of a data layer is akin to how CSS is used to separate out presentation from Web content.
