paragraph 6 has a piece of a word which is highlighted
it is associated to 40 seconds in on the video 2 paragraphs above
it is a piece of text linked to a heading lower in the page
it is a piece of text linked to the 4th image in a gallery in the page
it is a piece of text linked to the 1920s which is listed in the timeline on the page
All of these are direct additional context provided w/ other items within the same document. These are done via ID / schematic association and the specialized link between these provide so in the following manner:
[ ] drop down which is a grouped select list so that it shows Headings (and then lists them) Videos (and lists them), etc. Anything that can be anchored or deep anchored
[ ] taxonomy association. Concepts come from marking something as a page type concept in the site. This is almost like a smart collection as far as additional visualization of the same data #1933
[x] time code / deep reference using hax hooks to add short cut to bar for seconds into video or active slide or ID reference for headers, etc (generate deep link)
