# This is an ontology for expressing alignment between classes, properties, and instances of 
# different ontologies, whether they are developed independently or versions of each other. 
# As used here, alignment is a looser relationship than equivalence, so alignment statements
# should be taken to be compatible with, but not logically reducible to, sameClassAs, 
# samePropertyAs, and sameAs statements. The intention of this format is that it allows for 
# more flexible mapping between ontology elements, including 1-n and n-1 map cardinality 
# and instances-to-class mapping.
