è Name / epithet / author(s) è Naming of catalogue units (species and below) è Naming of undetermined units at higher ranks (genus, family, order, class, etc.) Species level entries: Genus level entries: Family level entries: Order level entries: Class level entries: Family level entries: Order level entries: Class level entries: è Using names as part of hierarchical classification THE TAXONOMY MODULE: Naming

 Name elements stored on 3 tabs  Hybrids mixed with other names  Overlap between tabs  Possibly superfluous fields THE TAXONOMY MODULE: Naming

Buschbom 01/01/2005 Citation  Name elements stored on 2 tabs  Name string automatic from second tab  Tab switching and name strings  Infraspecific ranks as defaults  Additional default ranks to accommodate ICZN  All principal name elements on single tab THE TAXONOMY MODULE: Naming

THE TAXONOMY MODULE: Typification Potential overlap with data stored in Catalogue Catalogue = customizable vs. Taxonomy module = standardizable Typification data stored on Citations Tab - Taxa as types not possible

Status Reference Source Type Holotype Kalb, Biblioth. Lichenol. 59: 16 (1984) Original Status Reference Source Type Lectotype McCarthy, Lichenologist 13: 32 (1999) Secondary Allows typification at each level Additional information Rank selection could allow tab switching between specimen-based (species and below) and taxon-based (above species) typification THE TAXONOMY MODULE: Typification

THE TAXONOMY MODULE: Nomenclature Inflexible data handling Mixes nomenclature with synonymy with synonymy Possible attributes: Illegitimate = later homonym = superfluous Invalid = nomen nudum = no type = no diagnosis = no attribute (sp.n.) Conserved name Proposed conserved name Rejected name Proposed rejected name

Flexible data handling Additional name information THE TAXONOMY MODULE: Nomenclature Diversity of nomenclatural attributes stored in data instead of being invariably reflected in field structure

THE TAXONOMY MODULE: Classification Should be part of data, not separate field Accommodate ranks preferably used by ICBN and ICZN by tab switching? How accommodate alternative and phylogenetic classifications?

Alternative parent for each name record Phylocode THE TAXONOMY MODULE: Classification Current implementation allows for 1-parent-only relationships Alternative classifications laid out as lexica/thesauri?

Parent relationships Do data have to be records (internal links)? THE TAXONOMY MODULE: Classification Classification is reflected in unique parent relationships (n-1) Can these be populated/updated/changed by referring to external source?

Homotypic Cluster Heterotypic Cluster Pseudotsuga nigra Pinus nigra Picea nigra Abies nigra Synonymy Cluster Illegitimate Names and Orthographic Variants (all can have homotypic clusters!) Pseudotsuga alba Pinus alba Picea alba Abies alba Leguminosae vs. Fabaceae (Accepted Alternative Names) Gibberella vs. Fusarium (Alternative Pleomorphic Form-Names) Lopadium epiphyllum vs. Lopadium epiphyllum (Homonymic Heterotypic Combination) Heterotypic Alternative Names (all can have homotypic clusters!) Data model to establish functional synonymy clusters in taxonomy THE TAXONOMY MODULE: Synonymy Abies alba (Isonym) Picea alba (Superfluous Combination) Abies thaxteri (Replaced Name) Abies viridis (Alternative Name) Abies conifera (Superfluous Name) Pinus albus (Orthographic Variant) Picea allba (Misspelling)

Bug in system? THE TAXONOMY MODULE: Synonymy Successfully establishing synonymy clusters depends on correct use of: Currently accepted? Is basionym? Kind of synonymy (Synonym status)

Separation between synonym types (separate tabs?) THE TAXONOMY MODULE: Synonymy Successfully establishing synonymy clusters depends on correct use of: Currently accepted? Is basionym? Kind of synonymy (Synonym status) Security features?
