Cross-Media Linking Flexible Document Representation Cross-Media User Interfaces

What is Wrong with Digital Documents? 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. Ted Nelson, Geeks Bearing Gifts: How the Computer World Got This Way, Mindful Press 2009 Existing document formats often based on the simulation of paper affordances on desktop computers B.

What is Wrong with Slideware? ▪ Simulation of physical slides ▪ limited space due to slide concept ▪ linear navigation ▪ monolithic documents ▪ difficult to reuse content and embed rich media types

MindXpres Presentation Platform ▪ Flexible representation of presentations ▪ use of structural RSL links ▪ separation of content and structure ▪ Extensible platform ▪ content-based approach ▪ cross-media content reuse via transclusion ▪ non-linear navigation and zoomable user interface ▪ associative linking ▪ rich media types R.
