Portion of the declarations of membership and rank order for a domain hierarchy oriented around exploratory sequence annotation. The first two entities (prefixed by the :dom command) create two domains, one based on short sequence alignments, and the other on pathway-related information; within each of these domains, various sources and classes native to the data integration engine's schema claim membership. The last entity (prefixed by :ord) defines the order for the domain, in increasing rank, as appropriate for the task at hand.
