r36395 r36404 25 25 description6=<p>The collection configuration file, <tt>collectionConfig.xml</tt>, specifies a single full-text index containing <i>dc.Description</i> metadata and overrides Greenstone\'s custom <i>gsf</i> format templates <tt>DocumentHeading</tt> and <tt>DocumentContent</tt> (XSL). When a document is displayed, the <i>DocumentHeading</i> format statement puts out its <i>dc.Subject</i>. Then the <i>DocumentContent</i> statement follows this with <i>screenicon</i>, which is produced by <i>ImagePlugin</i> and gives a screen-resolution version of the image; it can be hyperlinked to the <i>dc.OrigURL</i> metadata -- that is, the original version of the image on the remote OAI site. Since this is no longer available on the web, it is now hyperlinked to the full version of the image file. This is followed by the image\'s <i>dc.Description</i>, also with a hyperlink; the image\'s size and type, again generated as metadata by <i>ImagePlugin</i>; and then <i>dc.Subject</i>, <i>dc.Publisher</i>, and <i>dc.Rights</i> metadata. <a href="_sampleoid_">This</a> is the result.</p> 26 26 27 description7=<p>There are two browsing classifiers, one based on <i>dc.Subject</i> metadata and the other on <i>dc.Description</i> metadata (but with a button named "captions"). Recall that the <i>AZCompactList</i> classifier is like <i>AZList</i> but generates a bookshelf for duplicate items. In this collection there are a lot of images but only a few different values for <i>dc.Subject</i> metadata.</p>27 description7=<p>There are two browsing classifiers, one based on <i>dc.Subject</i> metadata and the other on <i>dc.Description</i> metadata (but with a button named "captions").

In this collection there are a lot of images but only a few different values for <i>dc.Subject</i> metadata.</p> 28 28 29 29 description8=<p>It\'s a little surprising that <i>AZCompactList</i> is used (instead of <i>AZList</i>) for the <i>dc.Description</i> index too, because <i>dc.Description</i> metadata is usually unique for each image. However, in this collection the same description has occasionally been given to several images, and some of the divisions in an <i>AZList</i> would contain a large number of images, slowing down transmission of that page. To avoid this, the compact version of the list is used with some arguments (<i>mincompact</i>, <i>maxcompact</i>, <i>mingroup</i>, <i>minnesting</i>) to control the display -- e.g. groups (represented by bookshelves) are not formed unless they have at least 5 (<i>mingroup</i>) items. To find out the meaning of the other arguments for this classifier, execute the command <i>classinfo.pl AZCompactList</i>. The programs <i>classinfo.pl</i> (for classifiers) and <i>pluginfo.pl</i> (for plugins) are useful tools for learning about the capabilities of Greenstone modules. Note incidentally the backslash in the configuration file, used to indicate a continuation of the previous line.</p> … … 31 31 description9=<p>The <i>VList</i> format specification shows the image thumbnail, hyperlinked to the associated document, followed by <i>dc.Description</i> metadata; the result can be seen in the <tt>CL2</tt> classifier browser. The <i>Vlists</i> for the classifiers use <i>numleafdocs</i> to switch between an icon representing several documents (which will appear as a bookshelf) and the thumbnail itself, if there is only one image.</p> 32 32 33 description10=<h3>The Greenstone OAI server</h3><p>Greenstone comes with a built-in OAI data provider. This runs as a CGI program called "oaiserver.cgi", and is installed in the Greenstone <i>cgi-bin</i> directory. It can be accessed via the same URL as the Greenstone library (replacing "library.cgi" with "oaiserver.cgi"). If you are using the Windows local library server, you must install a web server (such as Apache) to run the OAI server.</p>33 description10=<h3>The Greenstone OAI server</h3><p>Greenstone comes with a built-in OAI data provider.

This file specifies general information about the repository, and lists collections to be made accessible to OAI clients. By default, collections are not accessible. To enable a collection, add its name to the <i>oaicollection</i> list.</p>
