Hi Martin,
Brilliant initiative!
So many steps forward for Linked Data over this weekend.
I have hacked sameAs.org to conform to what will clearly become a crucial
standard.
However, this has exposed what may be a shortcoming.
Your colours (sic) are related to the IR; but would it not be much better if
they related to the NIR?
This is an interesting point, but seems to be more complex :-)
But we can offer that as an further output, so users can decide what to
use themself.
As a starting point it would be perfect if
http://dbpedia.org/resource/Edinburgh is being colored the same way in
different tools.
Maybe this could lead to a more frequent re-usage of URIs. A further
advantage is that it can be reimplemented without using any web service.
A second step could then be if http://dbpedia.org/resource/Edinburgh and
all the other 120 listed resources about the same thing are coloured the
same.
The usability of tools would be heavily improved but needs a further
pre-processing step.
You will see thatwww.sameas.org/?uri=http://dbpedia.org/resource/Edinburgh
illustrates the point.
(and takes rather a while to load, while it finds all the colours and renders
the stuff!)
Would it not be better if COLD was "sameAs" aware?
You could query sameAs.org and find the colour of the canonical URI (the
foaf:primaryTopic in the RDF), and render that colour for any of the URIs?
We can offer that approach as well. and integrate respective code
snippets on our snippets page (
http://cold.aksw.org/index.php?page=snippets).
I will add sameAs.org on our tools (
http://cold.aksw.org/index.php?page=tools) page? Is that ok for you? :-)
Or maybe offer it as an option.
I think I will go to only showing the colour for the main URI soon, as the
intention is clearly to establish colour association in the user's mind.
One day we will be able to dispense with URIs altogether and just use colours!
ok, there is a 24bit limitation but i would like that idea as well :-)
Best
Michael

Hi Michael,
There is a small bug in the Turtle representation: in e.g. my colour
<http://companjen.name/id/BC> a rdf:Resource ;
cold:colour loc:26bd27 .
cold:color a owl:AnnotationProperty ;
rdfs:label "color"@en ;
rdfs:domain rdf:Resource ;
rdfs:range dbpo:Colour .
... you mixed up "color" and "colour". That's all :)
thank you for reporting this small bug. Now it should be fixed.
By the way, I really like my colour!
Yes your color is quite good.
Its even more fancy than my one:
http://cold.aksw.org/index.php?iri=http%3A%2F%2Faksw.org%2FMichaelMartin
Maybe we should open a contest about beauty WebId's :-)
All the best
Michael

Dear all,
On behalf of AKSW research group [1] I'm proud to announce an innovative
approach for coloring the Data Web. The monochromacity of the Data Web
is widely perceived to be the main obstacle for a wider deployment and
penetration of Linked Data and Semantic Technology (cf. e.g. [2]).
So far, no unified algorithm existed for coloring the Data Web. With
http://cold.aksw.org we developed a key base technology able to color
URIs and IRIs (future work will focus on literals, whole triples,
containers, reifications etc.). Features of COLD include:
* globally unique URI/IRI coloring algorithm
* cross-application color consistency
* ensuring color fidelity
* built in color attack prevention
* support for vocabulary/ontology coloring
* 24bit / 16,777,216 color support
* integrated RGB support, extensibility for other color models
* example implementations in five programming languages
* small memory and code footprint
We deem COLD to be the key technology for the ultimate breakthrough of
semantic technologies. COLD is already implemented in a number of tools
including CubeViz [3]. Please beware of brand infringement, due to color
trademark protection (cf. [4]).
Best,
Michael Martin
