Hi Ryan,

The alignment format [1] might also be interesting. It can be used for 
for data and schema alignment. This format is supported by many 
matchers, have a look at the ontology alignment evaluation initiative [2].
Also, the approach of separating the alignment as an output of a matcher 
and the linkset as the set of owl:sameAs definitely makes sense. You 
might be interested in looking at the architecture we propose around 
that idea [3].
