I have no idea about the API/code support in Calligra, but...

Ignore Nepomuk for now (it's "just" an implementation and set of ontologies), 
start away with what RDF and ontologies are about and used for, to get the 
idea how the additional data/info which is stored using RDF is helpful, 
especially for searching/querying certain data from the whole data set.

This might be good for a start: http://www.rdfabout.com/quickintro.xpd
More detailed is this: http://www.w3.org/TR/rdf-primer/
(others might have better links, I just googled and quickly checked the 
content of the first links returned, lazy me)
