I'm looking for any information regarding current formats for describing (node & arc) graphs. I'm after a format to use for a graph visualisation project, but the most promising candidates I've found have significant flaws and/or appear to be inactive projects. I'd be interested to hear what formats people are using in this domain. What I've come across so far are : XGMML - contains masses of detail relating to how the graph should be visually represented (e.g. Graphic object attribute stipple - The name of the stipple (pattern) to be used for the graphic object). Perhaps a case here for XGMML-Reduced, pull out everything that SVG covers? RGML - this would be nice, only there doesn't appear to be much of a mechanism (beyond core RDF) for associating resources to graph elements - notably rgml:label is a Literal, how might one label a node with something richer? GXL - seems inactive. Cheers, Danny. --- Danny Ayers <stuff> http://www.isacat.net </stuff>
