DELTA programs and documentation

DELTA programs originally developed at the CSIRO Division of Entomology
Support and documentation
Other DELTA programs
The DELTA format (DEscription Language for TAxonomy) is a flexible method for encoding taxonomic descriptions for computer processing. The programs described in this section were originally written for Microsoft Windows by the CSIRO Division of Entomology, and were ported by The Atlas of Living Australia (ALA) to run under Windows or Mac OS X.
Intkey is included with the complete set of programs, but can be installed separately (CSIRO version), or downloaded and run without installing (either version). Note that the ALA version requires installation of the Java Runtime Environment (JRE).
Download and run the Intkey installation file. The installation guide contains detailed information about installing Intkey and the other DELTA programs.
Download the zipfile containing the CSIRO version (1.4 MB) or the ALA version (4.6 MB) of the app. On your internal hard disk or on an external disk or thumb drive, create a folder ‘intkey’ to hold the app and related files, and unzip the downloaded file into that folder. If using the ALA version, make sure that the JRE is installed.
To run Intkey, double click on the file intkey5(.exe) (CSIRO version) or Intkey(.exe) (ALA version). In the ‘Select data set’ dialog, type or paste the local filename or the URL (Web address) of an Intkey initialization file. (Your Web browser will have an option for copying the URL of a link.)
To test the app, you can use the initialization file ‘sample\intkey.ink’, which is included with the downloaded files, or the URL ‘http://delta-intkey.com/lep/lep.ink’. The latter key is designed for exploration of interactive identification, and for use in training courses and workshops. When evaluating interactive-key apps, it’s important to carry out real identifications, rather than pretending to identify familiar organisms, when the answer is known beforehand. This key is suitable for that purpose. The characters don’t require special knowledge, and the illustrations can be used as ‘specimens’ to be identified.
If you want to be able to run Intkey by double clicking on the name of an initialization file, or by clicking on a link in a Web page (for example, in the datasets at delta-intkey.com/www/data.htm), you need to associate the file type ‘.ink’ with the app file intkey5.exe (CSIRO version) or Intkey.exe (ALA version). For information on how to do this in Windows, see http://www.computerhope.com/issues/ch000572.htm. This association is carried out automatically if you install Intkey.
When you exit from a key, you will be given the opportunity to add it to an index file for easier future access.
Intkey and the DELTA Editor will run in 32-bit or 64-bit Windows. The other programs will run only in 32-bit Windows.
