At the core of jExperience interaction with the browser, the digitalData object is built by jExperience and inserted into the page (window.digitalData) before it being rendered by the visitor’s browser.
Wem.js, jExperience Javascript tracker uses the digitalData object as a data source for many of its functions. This object is added automatically by the jExperience module and is necessary for its tracker. It contains data related to the current page, the current site and custom configuration for required properties.
The digitalData object was defined by the Customer Experience Digital Community Group under W3C. The group published a final report available at this address: https://www.w3.org/2013/12/ceddl-201312.pdf
This report was used as a foundation for the team developing jExperience to generate the window.digitalData object.

Current scope, this value is used across all of the objects generated by wem.js
The site object contains information about the current Jahia site; it is typically used to build the source of the page view event.
The page object contains information about the current Jahia page, it is typically used to build the page view event, but it’s also used as a source for all other events coming from the page, like click, form submission, etc …
The wemInitConfig object contains various configurations reused by the tracker to load the current user profile data and add it to the data layer.
