[ckan-discuss] Next version of the LOD cloud diagram. Please provide input, so that your dataset is included.

[Ed Summers]

It was awesome to see that the new LOD Cloud leverages data in CKAN. I
really like the idea of driving more people to documenting Linked Data
packages on CKAN in order to get their content into the LOD Cloud.

I have been doing a bit of playing around with the Protovis JavaScript
library recently to visualize owl:sameAs links in the Billion Triple
Challenge dataset [1]. It's pretty easy to use, at least in the
simplistic way I have been playing around with it. I thought it would
be fun to use the same approach to graphing the LOD Cloud using the
CKAN API. So I went and did it [2]. The fact that it only took an hour
or so was all due to the way you have leveraged CKAN, and CKAN's
lovely REST API.

While processing the data I think I noticed 50 packages in the
lodcloud group which referenced other CKAN packages
(package['extras']['links:*'] in the json) that were not also in the
lodcloud group. I didn't actually dig in to see if they are definitely
on CKAN, but at least a few of them already were. I haven't been
following the earlier discussion too closely, to know if this is
already a known issue. I'd be willing to help add the packages to the
lodcloud group if you are looking for an extra set of hands.

Here's the list of package links that I think are broken, the one on
the right not existing in the lodcloud group.
