Downloading files for use offline

9 April 2006

M. J. Dallwitz

This file describes how to download and install data files that are physically located at this site (delta-intkey.com), for use offline.

For each dataset, there are usually two sets of files: one for use with Web browsers, and one for use with the interactive identification and information-retrieval program, Intkey. The image files (if any), are shared by the two access methods.

Downloading complete sets of HTML descriptions (Web pages), RTF descriptions, and images is best done using ftp, as most Web browsers can only download files one by one.

The files are available by anonymous ftp from

delta-intkey.com

The files must be downloaded in binary mode.

Each dataset is contained in a subfolder of the root folder. The names of the subdirectories are normally abbreviations of the dataset name. For example, /angio contains the files for the angiosperm families. (It’s best to look at the datasets index first — your Web browser will show you the subfolder names.)

Web-browser files

There is an index file, index.htm, in each data folder. For example, /angio/index.htm contains the index for the angiosperm families.

HTML descriptions (if available) are in the subfolder ‘www’ (e.g. /angio/www).

Illustrations, if available, are normally in the subfolder ‘images’ (e.g. /angio/images). In a few cases, several related datasets share a single set of images, and the folder structure is slightly different. For example, the package ‘Commercial Timbers’ has separate versions for different languages. The English data are in /wood/en, the German data are in /wood/de, and the images are in /wood/images.

The folder structure relative to the main Intkey data files must be reproduced on your local computer. For example, if you place index.htm in c:\angio, then the descriptions must be placed in c:\angio\www, and the images in c:\angio\images.

Intkey and RTF files

Intkey itself can download its main data files over the Web. The Web index to each dataset contains a link ‘Identification and Information Retrieval’. The ‘Identification and Information Retrieval’ page contains a link to the Intkey startup file for the dataset (e.g. /angio/angio.ink). When this link is followed, Intkey downloads and expands its main data files. When you exit from Intkey, or start a new dataset, you will be given the opportunity to save the main data files, in compressed form, on your computer. Intkey will also store information about the location, on the Web, of any images and RTF descriptions. When you run the dataset again from your local computer, you will need to be online to view images and RTF descriptions (unless they are still cached from your previous Web session). To have local access to all images and descriptions, they must be downloaded as described below.

The main Intkey data files, and various subsidiary files, are in a zipfile namei.zip (or a self-expanding zipfile namei.exe), where name is the (abbreviated) name of the dataset. For example, /angio/angioi.zip contains the Intkey files for the angiosperm families. Download this file into any folder. (You can skip this step if the file has already been downloaded and saved by Intkey.) Then unzip the file in the folder that you are using for that dataset (e.g. c:\angio).

RTF descriptions, if available, are in the subfolder ‘info ’ (e.g. /angio/info).

Illustrations, if available, are normally in the subfolder ‘images’ (e.g. /angio/images). In a few cases, several related datasets share a single set of images, and the folder structure is slightly different. For example, the package ‘Commercial Timbers’ has separate versions for different languages. The English data are in /wood/en, the German data are in /wood/de, and the images are in /wood/images.

The folder structure relative to the main Intkey data files must be reproduced on your local computer. For example, if you placed the main Intkey files in c:\angio, then the RTF descriptions must be placed in c:\angio\info, and the images in c:\angio\images.

When namei.zip is unzipped, it creates a file intkey.ink (or intkey.ini) in the main folder (e.g. c:\angio\intkey.ink). To start the key, open this file in Intkey.
