Recent SUMO, Wordnet, Yago, and DBpedia mapping also provides another 
mechanism for demonstrating all of this.

Basically, SUMO, OpenCyc, UMBEL, Yago etc.. remain strange second-class 
citizens of interest re. LOD, but in due course this will change, since 
without these compliments, the real power of Linked Data will remain 
mercurial across all practical dimensions.

Linked Data does provide both substrate and exploitation mechanism for 
ubiquitous smart data.

Note to all: you cannot have ubiquitous smart data without an ability to 
deal with context fluidity; someone will always have a different point 
of view, and that should be an acceptable part of the deal re. Linked 
Data driven metadata :-)
