PhD week 8: Structuring taxonomic descriptions

Taxonomic data models
Biological taxonomy is the science of categorising the plants and animals that share this world with us. A critical part of this characterisation is the writing of a description detailing the features which (done well) allows others to identify members of the species in question. Traditionally, this is a piece of prose that is very technical and very dry to read. There is, however, a move towards standardising and atomizing descriptive information, to enable it to be more readily re-used for a variety of applications.

The first attempt at this was the DELTA format, which was drafted as early as 1975. This format is becoming somewhat dated, and efforts are being made to produce an XML-based standard, known as Structured Descriptive Data (SDD).

Computer programs that can be used to produce these structured datasets include LUCID, xper2 and Open DELTA. Somewhat more complex is the taxonomy editor produced by the European Distributed Insitute of Taxonomy, that appears to be the tool for populating their scratchpads.

For some fairly detailed commentary regarding the promises and challenges offered by this revolution in taxonomic data management, ZooKeys published a special issue on e-Infrastructures for data publishing in biodiversity science.

I am revising a large genus (~70) of true bugs. I am currently using DELTA for coding characters and generating natural descriptions. Do you have recommendations as to what is the best tool for doing taxonomic descriptions? I find DELTA a bit too rigid to be able to capture the vast structural variations seen in ~70 species. Thanks.
