Research domains

Some examples: film and performance studies, social science, literary studies, genetics, astronomy, linguistics, pathology..

Research methods

What is the researcher doing and why? ● What methods are they using to create

and process data or information? ● Are they qualitative and quantitative

research methods? ● Is the processing by a human or with

computer settings?

Example: annotation (contextual)

Genetics: electronic, literature, sequence-based. Geoscience: map, map document, data frame, graphic.Linguistics: descriptive, analytic, time sequence, text. Biomedicine: graphics, notes, marker.

Managing multimedia

Content, document, information, data management, what’s the difference?Multiple components, are they embedded and layered, or in different file formats? Captured and stored within an application, are components as separate files to or part of the primary object’s file format?

Three applications

How do they store/package digital material? ● Final Cut Pro: project, media source,

render and case files. ● ArcGIS: map documents, layers and

datasets. ● WordPress: posts, pages, comments,

categories and tags.
