Creative Commons Rights Expression Language (also see "A Few License Labels")

Yes! There is a way to express license information in RDF. That is, there is a way to make copyright information machine readable. Once labeled, this frees the human to do other things instead of aggregating material that falls under the appropriate license.

Welcome to Creative Commons Rights Expression Language (ccREL). Also see an article for it on Wikipedia.

Please compare this to a previous post titled, "A few license labels".

CmapTools

In addition to Tufts Universities' Visual Understanding Environment (VUE), I also discovered CmapTools. It appears a bit older than VUE, but in some ways is more functional. Like VUE, it provides a means of building concept maps. Concept maps are like mind maps, except that they do not have to have a central node. See concept maps on Wikipedia for more information.

I am very interested in expressing concept maps semantically so that they are machine readable. This could make the information useful for other purposes such as other visualizations. For example, see my previous post, "Network Visualization Within Diaspora (cont.)". As usual, the bioinformatics community seems to be ahead of the game. See a website on Semantic Maps for Bioinformatics.

A few recent findings

Simantics is one of the most sophisticated open source project-based tools I've seen. It reminds me of tools developed by Dassault Systemes. Kune is based on Apache Wave (formerly Google Wave) and is similar to Rizzoma. This relation and further relations may be found on Wikipedia under Apache Wave. Cytoscape is a wonderful visualization tool from the Bioinformatics community. It allows for RDF visualization and SPARQL Queries.
