What is Wrong with Digital Documents? A Conceptual Model for Structural Cross-Media Content Composition and Reuse
Presentation given at ER 2010, 29th International Conference on Conceptual Modeling, Vancouver, Canada, November 2010
ABSTRACT: Many of today's digital document formats are strongly based on a digital emulation of printed media. While such a paper simulation might be appropriate for the visualisation of certain digital content, it is generally not the most effective solution for digitally managing and storing information. The oversimplistic modelling of digital documents as monolithic blocks of linear content, with a lack of structural semantics, does not pay attention to some of the superior features that digital media offers in comparison to traditional paper documents. For example, existing digital document formats adopt the limitations of paper documents by unnecessarily replicating content via copy and paste operations, instead of digitally embedding and reusing parts of digital documents via structural references. We introduce a conceptual model for structural cross-media content composition and highlight how the proposed solution not only enables the reuse of content via structural relationships, but also supports dynamic and context-dependent document adaptation, structural content annotations as well as the integration of arbitrary non-textual media types. We further discuss solutions for the fluid navigation and cross-media content publishing based on the proposed structural cross-media content model.

Digital Documents as a Paper Simulator?
Vannevar Bush
Ted Nelson
Most people don't understand the logic of the concept: "What You See Is What You Get" is based on printing the document out ("get" means "get WHEN YOU PRINT IT OUT"). And that means a metaphysical shift: a document can only consist of what can be printed! [...] No overlays [...] – PAPER UNDER GLASS.
When data of any sort are placed in storage, they are filed alphabetically or numerically, and information is found (when it is) by tracing it down from subclass to subclass. It can be in only one place, unless duplicates are used [...] The human mind does not work that way. It operates by association.
