Could be useful re. our Sponger Meta Cartridges which already perform 
lots of lookups across LOD etc.. This is how we mesh data from UMBEL, 
Calais, Zemanta, and New York Time data into the output of our 
RDFization processing pipeline, for instance.

This language could make the Meta Cartridge feature more pluggable and 
amenable to 3rd party Cartridge Developers, especially as we don't want 
to take on the burden of building Cartridges for every potential data 
source type re. Linked Data Web :-)


- Programmer Guide (*draft*)

On a different note, could we please have the Linking Drug Data (LDD) 
effort cross Linked to the Linking Open Data (LOD) effort within ESW 
Wiki. I should be able to locate the LDD RDF archives with ease knowing 
they've been prepared in line with our generally accepted best practices.
