Hi Kingsley, I am right with you - finding stuff is hard.
But I do think we could make it easier for all of us.
Just the esw wiki alone requires me to put every set I create into a bunch of
place, for example, at least:
* [[http://esw.w3.org/TaskForces/CommunityProjects/LinkingOpenData/DataSets
DataSets]]
* [[http://esw.w3.org/DataSetRDFDumps RDF Dumps]]
* [[http://esw.w3.org/SparqlEndpoints SPARQL endpoints]]
* 
[[http://esw.w3.org/TaskForces/CommunityProjects/LinkingOpenData/DataSets/Lin
kStatistics Link Statistics]]


In the end, I just don¹t manage it, partially because it entails editing a
large wiki page for most (although the move to MW must be an great
improvement).

So if I find the whole thing laborious.
Telling people to go and edit multiple pages is not really customer oriented
(I view the publishers as our customers in the Linked Data world).
  
      
I agree, so what about del.icio.us bookmarks?
    
True, it's a "bit", however it only gives a URI and some tags, but providing
the metadata is more complicated.
  
For me, it gives me URLs that feed my RDFizer i.e., Virtuoso Sponger (as 
demonstrated via the URIBurner instance). Anything in Del.cio.us ends up 
in the Web of Linked Data cloud. All you need is a bookmarklet, a 
del.icio.us link visit, and the rest is done. Of course fidelity of 
description is an item of perpetual improvement, but that's much easier 
once you have Generic HTTP URIs exposed from a Web accessible Linked 
Data Space.
And it would be yet another place to put and find dataset metadata.
  
Does anyone want to step up to the plate and do a swish repository for this
data, with easy entry (including RESTful) and publishing as html, Linked
Data, json etc. using voiD, etc?
  
      
Even better, I am sure this can be assembled in bits, as Melvin has
already demonstrated :-)
    
Actually, what Melvin demonstrated was neat, but only about re-publishing
and consuming.
The trouble with "bits" is that there are usually quite a few of them, and
so they (such as delicious) will only increase the number of places with
which a dataset publisher needs to interact.

The esw pages are exactly the sort of structured data that we claim to be
able to deal with - surely someone has the tools and the time to deploy them
(!) to do a proper data management of this metadata around RDF?

Maybe a PG wants to use it as a use case for Linked Data research?
I'm sure the Sindice team has much of the data already in RDF?
  
We also have most of the data in RDF too :-)

The inconsistencies I am concerned about effect all ecosystem players.

Thus, we ultimately comeback to a DBpedia template for LOGD, that 
clearly identifies:

1. RDF Data Set URLs
2. SPARQL Endpoints
3. Linked Data URIs where publishing of resolvable Web Scale Identifiers 
has occurred.

The items above are equally valuable and distinct within the Linked Data 
ecosystem.

All,

I continue to struggle with easy discovery of Government oriented Linked
Data (UK and U.S. are examples). Basically, a long time ago, we
established some core principles for Linked Open Data published to the
Web. The components where broken down as follows:

1. Publish RDF Data Set archive URLs to a well known location --
http://esw.w3.org/DataSetRDFDumps
2. Publish SPARQL Endpoints -- e.g., <http://esw.w3.org/SparqlEndpoints>
3. Publish Linked Data -- an home page or deeply linked URI will do.

DBpedia still provides a very nice template for the above.

Unfortunately, most of the Govt oriented Linked Data projects haven't
quite adopted the scheme above thereby making the process of discovering
items 1-3 quite tedious.

Suggestions:

I think we can tackle this problem by doing the following:

1. Use the moniker Linked Open Govt Data (LOGD) for all Govt. oriented
Linked Data projects
2. Use #hashtag #logd on Twitter and "logd" for tagging on del.cio.us --
one data is on del.icio.us or Twitter, its basically part of LOD via
RDFizers etc..

So Far I have:

1. http://delicious.com/kidehen/logd  -- del.icio.us tag
