Textual images have been removed from the interface; they are now done using CSS (Cascading Style Sheets). The Greenstone Language Pack is no longer needed.

398<Text id="0202">Most people download the Windows distribution from <Link>http://www.greenstone.org</Link>, which contains the latest version of Greenstone. There are several optional modules that must be downloaded separately (to avoid a single massive download): <b>documented example collections</b>, the <b>Export to CD-ROM</b> package, the <b>Language Pack</b> (Greenstone 2.62 and earlier) and <b>Classic Interface Pack</b> (Greenstone 2.63 and later). There is also the set of <b>sample files</b> used in these exercises. (To reduce the download size the documented example collections are distributed in unbuilt form and need to be built.)</Text>
399<Text id="0203">You need <b>Java</b> to run Greenstone. You might already have it; otherwise download it from <Link>http://java.sun.com</Link>. To work with image collections, you need <b>ImageMagick</b> (from <Link>http://www.imagemagick.org</Link>). </Text>

401<Text id="0204">Most Greenstone CD-ROMs start the installation process as soon as they are inserted into the drive, assuming that the AutoPlay feature is enabled on your computer. If installation does not begin by itself, locate the file <i>setup.exe</i> and double click it to start the installation process. (On the IMARK CD-ROM this file resides in the folder <Path>software_tools &rarr; Greenstone</Path>). If you download Greenstone over the web, what you get is the installer&mdash;just double-click it.</Text>
402<Text id="0206"><b>If Greenstone has been installed on your computer before, you should completely remove the old version before installing a new one</b>.

515</Comment>
516<Comment>
517<Text id="0244">There is another important difference that you should be aware of: Versions 2.60 and above are installed in the folder Program Files\Greenstone, whereas prior versions were placed in the folder Program Files\gsdl (these are both default locations that you could have changed during installation.) When upgrading to Version 2.60, if you want to save existing collections you must explicitly move the contents of your collect folder from the old place to the new one. Future Greenstone versions will be installed in the new place, Program Files\Greenstone, so this problem will not happen again.</Text>

1734<Comment>
1735<Text id="0640">One powerful use of regular expressions in the exercise was to clean up the <i>titles a-z</i> browser. Perhaps the best way of doing this would be to have proper title metadata. The metadata extracted from HTML files is messy and inconsistent, and this was reflected in the original titles a-z browser. Defining proper title metadata would be simple but rather laborious. Instead, we have opted to use regular expressions in the <i>AZCompactList</i> classifier to clean up the title metadata. This is difficult to understand, and a bit fiddly to do, but if you can cope with its idiosyncrasies it provides a quick way to clean up the extracted metadata and avoid having to enter a large amount of metadata.</Text>

1869<Text id="0676">The collection involves a mixture of plug-ins, classifiers, and format statements. The bulk of the work is done by PagedImgPlug, a plug-in designed precisely for the kind of data we have in this example. For each document, an "item" file is prepared that specifies a list of image files that constitute the document, tagged with their page number and (optionally) accompanied by a text file containing the machine-readable version of the image, which is used for full text searching. Three newspapers in our collection (all from the series Te Whetu o Te Tau) have text representations, and two (from Te Waka o Te Iwi) have images only. Item files can also specify metadata. In our example the newspaper series is recorded as ex.Title and its date of publication as ex.Date. This metadata is extracted as part of the building process.</Text>

2251<Text id="0789">In this exercise you export a Greenstone collection in a form suitable for DSpace. It is possible to do this from the Librarian Interface's File menu, which contains an item called Export... that allows you to export collections in different forms. However, to gain a deeper understanding of Greenstone, we perform the work by invoking a program from the Windows command-line prompt. This requires some technical skill; if you are not used to working in the command-line environment we recommend that you skip this exercise.</Text>

2277<Text id="0793">Exporting in Greenstone is an additive process. If you ran the export.pl command once again, the new files exported would be added&mdash;with different folder names&mdash;to those already in the export folder. For the kind of explorations we are conducting we might re-run the command several times. The -removeold option deletes files that have previously been exported.</Text>
