id_name number y primary key<br />

E. BOOS, W. BRAUN, R. MAY and J. OCHSMANN<br />

id_rank number y foreign key, points to table rank<br />

id_rank_2 number y y foreign key, points to table rank,<br />

used for the ‘botanical part’ of a<br />

cultivar name<br />

name varchar2(512) y taxon name<br />

name_1 varchar2(100) y y first name part of bi- or trinomina,<br />

single name of higher taxa without<br />

authors or other supplementary<br />

phrases<br />

epi_1 varchar2(100) y y 1st epitheton (species, sectio etc.)<br />

epi_2 varchar2(100) y y 2nd epitheton (the last below<br />

species)<br />

cultivargroup varchar2(100) y y<br />

cultivar varchar2(100) y y<br />

author_phrase varchar2(100) y y all authors incl. phrases like ‘auct.’<br />

etc.<br />

bp_standard number y y authors checked according to<br />

Brummitt and Powell (1992)<br />

hybrid varchar2(1) y y ‘x’ if hybrid, ‘+’ if graft-chimaera<br />

The names are not only stored as strings, but in an atomised form - each name part,<br />

the rank and the authors in a single field. At present one can get information on<br />

225,000 taxa via BIGTAX, but the redundancy of names is about 30%. The main<br />

causes of redundancy are differences in the spelling of names and their authors.<br />

The atomised structure of names will allow, at a later stage of development, the<br />

comparison and improvement of the names and authors and their spelling.<br />

At this time, a search for names will result in a list from which the user can select the<br />

names he is interested in, and view their common names or the synonymy. In a next<br />

stage it will be possible to search the repository by a hierarchy tree, which is based<br />

on a preferred taxonomic view, but maps all used names to this tree.<br />
