Hi Hugh,
First, apologies for the long delay in responding ... I was swamped in Feb/early March but have bubbled up now.

I think the gist of what you were saying is, 'why create yet-another-directory ... why not work with an existing one, ie., semanticweb.org, to improve it?'

In a nutshell, I think being able to publish N directories, with no advance coordination, as long as they conform to a common data exchange format, is the point.

I offer this and hope you'll appreciate where we I'm coming from.  The sem tech community has for over a decade been espousing the benefits of human and machine readable content however,  from time to time we've been guilty of not practicing what we preach.  In many cases directories have been HTML only which isn't re-usable for an LOD app. Please correct me if I'm wrong, but I believe semanticweb.org is a semantic media wiki site that contains primarily unstructured content.

The W3C directory[1], albeit another directory, is a structured content site.  The GLD WG created its directory to demonstrate the power of triples (triples under the hood, up & down), has some eye candy stats [2], and looks pretty thanks to HTML 5 & CSS, using Callimachus [3], a linked data management system.

Thus, this directory allows the data to be made readily available as both human readable & machine readable content which is the raison d'ętre of the W3C GLD Working Group.  It is a simple showcase app to help the LD community advertise their wares (projects, products, services), and does so using the set of standards we're telling governments they should use to make their data more accessible & re-useable.

So my feeling is that anyone can and should create their favorite directory BUT they should do it in a manner that others can re-use the content.   As you well appreciate,W3 projects are volunteer based efforts.  The directory definitely needs some usability improvements, no question.  All feedback is welcome.  In due course, I hope others take the directory data & mash it up with some other LOD to show something useful.

I hope that helps better explain our thinking on yet-another-directory.  (Plus, it was in our charter).

Cheers,

We meet at the end of this month for our second F2F to review the directory (and all our deliverables) & figure how to make it more useful. If that entails pointing to other sites or adding functionality to more relevant site, we'll happily consider any approach that adds value.
