Cosma / Communication / Knowledge / Realm



knowledge : the sum of what is known : the body of information, principles and truth acquired by humankind — Merriam-Webster

realm : (1) kingdom (2) sphere, domain — Merriam-Webster

knowledge realm : a kingdom, sphere, or domain for holding the body of information, principles and truth acquired by humankind — M.E. Hopper, Cosma 2



Cosma has a number of 3D interfaces that enable truly spatial Knowledge Navigation and invite exploration of the Knowledge Resources inventory hosted on this site.

You can use them to explore “Knowledge Realms” visually and spatially.

Toy Worlds@Kuula

This 360° image is the first in a series of Toy Worlds for exploring knowledge!

Places@Second Life

There is also a Welcome Area in Second Life. If you have a SecondLife account and software, then you can click the image below to explore the Welcome Area and the four other rooms (Solar Extremes, Gaia’s Greenhouse, World Travel Lounge and Walk-in-Art).

There is also a much older site that is an archive of the Knowledge Places (K-Places) project. The project began in 2006 and covered more than a million sq. meters of land in Second Life. The sites were made up of thematically organized spaces that used a variety of metaphors (Port, Park, Plaza, Pier, Palace and Paradise). You can find out much more about the overall project on the K-Places page.

The largest archival site is K-Park — it preserves the spaces and objects that were an interface to the Knowledge Realms.

Here is a video of an extended walk-through of the K-Places archival site.

This map shows where the archival site is located in Linden Village. If you have a Second Life account and software installed, then you can click the map to teleport there.

1.   The resources on this page are are organized by a classification scheme developed exclusively for Cosma.

2.   Collecting hundreds of thousands of Knowledge Resources over the course of decades is far easier than you would probably think. However, figuring out how to organize them in order to make them accessible is hard. Adding the additional constraint of needing to organize them into a literal map in order to create 3D interfaces to enable spatial Knowledge Navigation is a very sticky problem. There is a long history of how to deal with knowledge organization problems, but there is no perfect solution — there are only a series of trade-offs in adopting any ontology. In practice, Cosma does not use any one specific existing system to “layout” knowledge. Instead, the virtual spaces that serve as 3D interfaces to Cosma are laid out into “Realms” based upon an amalgamation of taxonomies for organizing reality into hierarchies and physical maps.
