Rank Specific Rootnodes in CDM Classifications

The CDM library provides methods to select nodes of a classification at a specific rank as virtual rootnodes.

These are named in the CDM jargon Rank Specific Rootnodes. An exact match to taxon nodes for a given rank is

sometimes not possible. In this case the next lower taxon node will be chosen. Otherwise the section made through

classification at the given ranks would be incomplete.

This functionality is implemented in the method ClassificationDaoHibernateImpl.listRankSpecificRootNodes(Classification classification, Rank rank, Integer limit, Integer start, List<String> propertyPaths, int queryIndex)
