This functionality is in two complementary parts:
Click On Citation: A student user who is reading a PDF in Reader and comes across a citation either in the body text or in the References and want to click on the citation to find out more about the source to decide if it supports what is stated in the paper (whether it looks authoritative and relevant) and whether it is worth accessing (and if so, have instant access). When clicking on a citation in Reader (in the body of the text or in the References) or in Author (in Edit or Read mode and in the Dynamic View), a Universal Citation Dialog is shown, as described herehttp://wordpress.liquid.info/08/universal-citation-dialog/frode/
Sort Reference Section: A teacher/examiner (and to a lesser extent student) who wants to asses the student’s use of citations and therefore would like to view the Reference section in different ways to get an insight into how the citations where used and in the case of a student user citing sources unknot to the teacher, to provide the same functionality the student has to click on a citation.
Click On Citation
Instant Access To The Citation Sources when reading the Document or in the the References section: Click on a citation to see ‘Universal Citation Dialog’. Click outside to dismiss.
Note: This will be designed so that in the future we can add buttons for Scholarcy integration. This should work on author exported PDFs but also for PDFs with citations in a known format such as [1], (1) and (author date), although that can be for a 1.1 version, it is not necessary for 1.0. However, in cases where the in-body citations are actual blue weblink to the References, it should definitely work though.
Sort Reference Section
Mockup
Its is here shown with the default sorting and the options ‘Author | Title | Occurrence | Time | Media’ in grey. User can click on any of these to sort, and click on ‘References’ again to sort by the default sorting.

In this case the user has clicked ‘Occurrence’ causing ‘Occurrence’ to be black and the References are now sorted by occurrence of citations in the document and document headings are show, such as ‘Introduction’ and ‘The Process’ in this example:

Alternative Layouts
A hope of the Visual-Meta approach is to allow the reader to more fully specify how the document should appear, including the styling of References as per conventional citation styles or in other ways. In this first rendering everything that is not author or title is greyed out. Note that these are just ideas, not for initial implantation:


[…] interactions such as Augmented Copying (copies with full citation information), References and Glossaries, as well as included information for how to parse tables, images and […]
