I would love to discuss ideas for visualizing aggregated data.

My personal focus has been on descriptive data about archival record groups and manuscript collections – with a stress on subject terms, quantity of materials (think total linear feet), subject terms and physical location of the materials.  I worked on a prototype visualization tool called ArchivesZ – but I have also seen many other inspirations for alternate approaches.

General topics I would like to include:

• leveraging standard markup, such as EAD (Encoded Archival Description), to support aggregation of  information about collections both within and across institutions
• the challenge of non-standard subject terms
• the coolest visualizations we think could be adapted to this type of data (my current obsession being the TimeRiver as exemplified by the NY Time’s box office revenue visualization)

I think that these ideas could coordinate well with what Laura mentioned in An archive aggregator.

Hello, THATCampers! Jeremy and I have been thinking about doing something on the genres and challenges of historical visualization in the digital realm.  We’d like to take a catholic view of visualization, considering everything from simple timelines to rich visual reconstructions such as Rome Reborn.  The former have gotten a pretty bad rap over the years, but as historians, we personally tend to be just as skeptical of the latter.  We’ll tell you why at Camp

One of the things we’d like to discuss in particular is what we see as one of the primary roadblocks facing quality historical visalizations of all kinds: the fact that there aren’t any good or widely accepted standards for describing and marking up historical events. Digital historians have managed to do a lot with maps and documents, places and artifacts, because there are good and well established metadata standards for describing these units of historical analysis (e.g. longitude, latitude, KML, MARC, OAI, etc.)  But we don’t have anything comparable for marking up happenings, which are at least as important as place and stuff to historical discourse.  There are, however, several contenders, including HEML, Microformats (hCard, hCalendar, Geo), and iCal, and we’d like to bounce these around to see if any stand out or can be made/hacked to do the job. At the very least, we’d like to start a conversation and encourage smart people to start thinking about just what a useful event standard would look like.

We were thinking Tom might introduce the session with some thoughts on historical visualizations in general and on timelines (and their persistent audience popularity) in particular.  Jeremy could then introduce the more specific (i.e. meaty/practical/useful) topic of event standards and demonstrate a proof-of-concept for implementing various Microformats for creating maps, timelines, and other visualizations with ads from the Virginia Runaway Slave database. To round out the session it would be great if we could find a couple campers with more experience working in Second Life, gaming, or 3-D reconstruction to join us to share their thoughts on the role (or lack thereof) of time-centered and other standards in more immersive visualizations. Finally, we’re totally open to suggestions from campers who would like to take the session in another direction altogether. Jump on board!
