Aside: Here's a less ugly version, @resource overrides @href if both  
are present:

<a href="http://en.wikipedia.org/wiki/Primary_motor_cortex" resource="http://dbpedia.org/page/Primary_motor_cortex 
" rel="sioc:topic">Primary motor cortex</a>

These are good points, and I don't really disagree with any of them,  
except perhaps in that I think that at the moment, data quality, a  
sensible URI scheme, wide coverage, perception of stability, and  
proper marketing are more likely to determine the success of a dataset  
in attracting links. It is true that at some point in the future, we  
will take it for granted that any serious dataset has all those  
attributes, and then the quality of the visual representation would  
perhaps close or break the deal.
