Re: [ANN] Linked Open Colors
Hi Sergio, Thanks for the update about this new, much needed service! While perusing the data from the command line with rapper I noticed that: http://data.colourphon.co.uk/id/colourscheme/triadic/ff6347 rdfs:label triadic colours to compliment Coral (ff6347) . ISO 01.070 [1] clearly defines this color as Tomato. I think we can all agree that the identity of colors is a solved problem, and it would be great if this Linked Data service could be updated to reflect this. I started a Doodle Poll to see if we can find a time to meet to discuss whether a W3C Working Group or Incubator Group might be needed to resolve this issue. //Ed [1] http://bit.ly/gWCSql [2] http://www.doodle.com/geyvyrx4wzgvky5s
