Started looking into 5 before switching technologies. Too much churn…

Taxonomy Module Issues using taxonomy.module to manage taxonomy Synonyms Common names Ranks Authorship Taxonomy is unstable data

Distinction between identification and tagging Sequence Can identity to unknown names

Managing TaxonomyADW taxonomy not based on any

single source Composite classification built from multiple

sources (Mammal Species of the World, Howard & Moore, ITIS)

Past: same database as managed was used in projects In theory, updates could be made public

faster Ancestry indexed as materialized paths

(best match for editing vs. search)

Managing Taxonomy: FutureSource data managed separately, to

minimize duplication of data between classifications

Build composite classificationsExport composite classifications as

simpler hierarchies to import into other project databases

UUIDs to maintain consistency
