I've been working on a set of best practices for Attribution by URI for 
LOD. The talks have been private (with a number of folks) for the last 
few weeks, but this post is poignant enough for me to change modes i.e., 
go public.

Yes, it is a shame that consumption of LOD data is already in full swing 
with original source URIs dislocated from the Linked Data Web value 
chain :-(

Bottom line, at the very least, we should collectively seek "Attribution 
by URI" for our data sets. Thus, if you consume 
<http://dbpedia.org/resource/Berlin> don't attribute in any of the 
following lossy forms:

1. "Thanks you DBpedia......"
2.  http://dbpedia.org

What we want is:

1. http://dbpedia.org/resource/Berlin (the URI of the entity Berlin the 
conduit to the data transmission that you consumed)

This can be done as follows:

1. RSS 1.0, RSS 2.0, Atom feed listing the data source names (URIs)
2. RDFa (expressing RSS 1.0)
3. If producing RDF, within the graph using terms from an Attribution 
ontology (we have example that will be pubished)

What these consumers need to be aware of is that HTTP is very powerful, 
meaning, it's not that difficult to dereference all the web resources 
that have consumed a URI but not attributed as requested by the 
publisher :-)

We know who's consuming our URIs (e.g. DBpedia) becuase the leave their 

The one missing piece of the Linked Data Web bootstrap has been an 
effective license scheme of publicly available Linked Data. I think this 
is about to change in a very big way.
