7shortDescription=<p>The Humanitarian Development Libraries represent a large collection of practical information aimed at helping reduce poverty, increasing human potential, and providing a practical and useful education for all. This subset contains about 25 publications--documents, reports, and periodical articles--in various areas of human development, from agricultural practice to economic policies, from water and sanitation to society and culture, from education to manufacturing, from disaster mitigation to micro-enterprises.</p>

11description1=<h3>How the collection works</h3><p>The DLS collection is fairly complex. If you're just starting out you might prefer to look at some other collections first (e.g. <a href="?c=documented-examples/wrdpdf-e&a=p&sa=about">Word and PDF demonstration</a>, or the <a href="?c=documented-examples/gsarch-e&a=p&sa=about">Greenstone Archives</a>, or the <a href="?c=documented-examples/image-e&a=p&sa=about">Simple Image collection</a>).</p>
12
13description2=<p>The <a href="_httpcollection_/etc/collect.cfg" target="collect.cfg">collection configuration file</a>, like all collection configuration files, begins with a line ("creator") that gives the email address of the collection's creator, and another ("public") that determines whether the collection will appear on the home page of the Greenstone installation. Note that setting "public" to "false" only removes it from the home page; it will still be accessible in the library to anyone that knows the URL (a=p&sa=about&c=coll-shortname).</p>
14
15description3=<p><b>Plugins</b>. The "plugin" lines in the <a href="_httpcollection_/etc/collect.cfg" target="collect.cfg">configuration file</a> give the plugins used by the collection. The documents in the DLS collection are in HTML, so <i>HTMLPlugin</i> must be included. The <i>description_tags</i> option processes tags in the text that define sections and section titles as described below.</p>
16
17description4=<p>The other plugins, <i>GreenstoneXMLPlugin, MetadataXMLPlugin, ArchivesInfPlugin, and DirectoryPlugin</i>, are used by Greenstone for internal purposes and are standard in almost all collections.</p>
18
19description5=<p><b>Searchable indexes</b>. The block of lines starting with <i>indexes</i> specifies what searchable indexes will be available. In this collection there are three: you can see them when you pull down the "Search for" menu on the <a href="?a=q">search page</a>. The first index is called "chapters", the second "section titles", and the third "entire documents". The names of these three indexes are given by three <i>collectionmeta</i> statements.</p>
20
21description6=<p>The contents of the indexes -- that is, the specification of what it is that will be searched -- are defined by the <i>indexes</i> line at the beginning of this block. This specifies three indexes, two at the section level (beginning with <i>section:</i>) and one at the document level (beginning with <i>document:</i>). The difference is that a multi-word query will only match a section-level index if all query terms appear in the same section, whereas it will match a document-level index if the terms appear anywhere within the document (which typically comprises several sections). The first and third indexes are <i>section:text</i> and <i>document:text</i>, and the <i>:text</i> means that the full text of sections and documents respectively will be searched. The second is <i>section:Title</i>, which means that <i>Title</i> metadata will be searched -- in this case, section titles (rather than document titles). The three indexes appear in the order in which they are specified on the <i>indexes</i> line.</p>
22
23description7=<p><b>Classifiers</b>. The block of lines labeled <i>classify</i> define the browsing indexes, called "classifiers" in Greenstone. There are four of them, corresponding to four buttons on the navigation bar at the top of each page in the collection (e.g. the <a href="?a=q">search page</a>): <i>subjects</i>, <i>titles</i>, <i>organisations</i>, and <i>howto</i> The <i>search</i> button comes first, then come the four classifiers, in order.</p>
24
25description8=<p>The first classifier provides access by subject. It is a <i>Hierarchy</i> classifier whose hierarchy is defined in the file <a href="_httpcollection_/etc/dls.Subject.txt" target="text">dls.Subject.txt</a> (the <i>hfile</i> argument); this file is discussed below. This classifier is based on <i>dls.Subject</i> metadata, and when several books appear at a leaf of the hierarchy they are sorted by <i>dls.Title</i> metadata (as you can see <a href="?a=d&cl=CL1.4.1">here</a>). The second classifier provides access by title. It is also a <i>Hierarchy</i> classifier, this time based on <i>dls.AZList</i> metadata, whose hierarchy is defined in <a href="_httpcollection_/etc/dls.Title.txt" target="text">dls.AZList.txt</a>. This file is discussed below. The third provides access by organization: it is a <i>List</i> classifier based on <i>dls.Organization</i> metadata. The <i>-bookshelf_type always</i> option creates a new bookshelf for each organization, even if only one document belongs to that category. The fourth provides access by "Howto" text: it is a <i>List</i> classifier based on <i>dls.Keyword</i> metadata. The <i>-bookshelf_type never</i> option prevents bookshelves being created even if two documents share the same keywords.</p>
26
27description9=<p><b>Cover images</b>. Greenstone looks for a cover image for each document, whose name is the same as the document's but with a <i>.jpg</i> extension. This image is associated with the document, and may be displayed on the document page (see below). Cover images can be switched off by setting the -no_cover_image flag for each plugin.</p>
28
29description10=<p><b>Format statements</b>. The lines beginning with <i>format</i>, called "format statements", govern how various parts of the collection should be displayed. The <i>VList</i> format statement applies to lists of items displayed vertically, such as the lists of titles, subjects and organisations, and the table of contents for the target documents. It is overridden for the search results list by the <i>SearchVList</i> format statement, and also for the <i>Howto</i> classifier by the <i>CL4VList</i> statement (CL4 specifies the fourth classifier).</p>
30
31description11=<p>The <i>DocumentText</i> statement governs how the document text is formatted, with <i>Title</i> metadata ([<i>Title</i>]) in HTML &lt;<i>h3</i>&gt; format followed by the text of the document [<i>Text</i>]. Setting the <i>DocumentImages</i> format statement to <i>true</i> ensures that cover images are shown with each document. The <i>DocumentButtons</i> statement calls for the <i>Expand Text, Expand Contents, Detach</i> and <i>Highlight</i> buttons to be shown with each document.</p>
32
33description12=<p>Most format statements contain a string specified in an augmented form of HTML. Metadata names in square brackets (e.g. [<i>Title</i>], [<i>Creator</i>]) give the value of that metadata; [<i>Text</i>] gives the document text. A hyperlink to the document can be made using [<i>link</i>] ...[<i>/link</i>]; an appropriate icon is produced by [<i>icon</i>]. Format strings can include {<i>If</i>}{... , ...} and {<i>Or</i>}{... , ...}; the first two give examples. These two are fairly complex format statements; we will not explain them here. In Greenstone, changes in format strings take effect immediately unless you are using the local library server, in which case the server needs to be restarted. This makes it easy to experiment with different versions of a format statement and see what happens.</p>
34
35description13=<p><b>Collection-level metadata</b>. The <i>collectionmeta</i> lines in the configuration file are also standard in all Greenstone collections. They give general information about the collection, defining its name, and a description that appears on its home page. The description (in <i>collectionextra</i>) can be seen on the DLS collection's home page (this text is part of it).</p>
36
37description14=<p><b>Language translations</b>. The last part of the <a href="_httpcollection_/etc/collect.cfg" target="collect.cfg">collection configuration file</a> gives the collection-level metadata in French and Spanish respectively. The languages are indicated by square brackets: [<i>fr</i>] and [<i>es</i>]. If there is no language specification, English is assumed by default. The configuration file shows accented characters (e.g. French <i>é</i>). This file is in UTF-8, and these characters are represented by multi-byte sequences (&lt;C3&gt;&lt;A9&gt; in this case). Alternatively they could be represented by their HTML entity names (like <i>&amp;eacute</i>). It makes no difference: they look the same on the screen. However, if the text were <i>searchable</i> it would make a difference; Greenstone uses Unicode internally to ensure that searching works as expected for non-English languages.</p>
38
39description15=<p><b>Description tags</b>. The description tags recognized by <i>HTMLPlugin</i> are inserted into the HTML source text of the documents to define where sections begin and end, and to specify section titles. They look like this: <pre> &lt;!-- &lt;Section&gt; &lt;Description&gt; &lt;Metadata name="Title"&gt; Realizing human rights for poor people: Strategies for achieving the international development targets &lt;/Metadata&gt; &lt;/Description&gt; --&gt; (text of section goes here) &lt;!-- &lt;/Section&gt; --> </pre> The &lt;!-- ... --&gt; markers are used to ensure that these tags are marked as comments in HTML and therefore do not affect document formatting. In the <i>Description</i> part other kinds of metadata can be specified, but this is not done for the style of collection we are describing here. Exactly the same specification (including the &lt;!-- ... --&gt markers) can be used in Word documents too.</p>
40
41description16=<p><b>Metadata Files</b>. Metadata for all documents in the DLS collection is provided in metadata.xml files, one per document folder. The <a href="_httpcollection_/import/r0087e/metadata.xml" target="text">metadata.xml</a> file for one book -- <i>Income generation and money management: training women as entrepreneurs</i> -- is a block of about ten lines encased in &lt;<i>FileSet</i>&gt; ... &lt;<i>/FileSet</i>&gt; tags. It defines <i>dls.Title</i>, <i>dls.Language</i>, <i>dls.Subject</i> and <i>dls.AZList</i> metadata. More than one value can be specified for any metadata item. For example, this book has two dls.Subject classifications. Both of these are stored as metadata values for this particular document (because <i>mode=accumulate</i> is specified; the alternative, and the default, is <i>mode=override</i>).</p>
42
43description17=<p><b>Hierarchy files</b>. Hierarchy files contain a succession of lines each of which has three items. The first item is a text string which is matched against the metadata that occurs in the <i>metadata.xml</i> file described above. The second item is a number that defines the position in the hierarchy. The third item is a text string that describes the node of the hierarchy on the web pages that Greenstone generates.</p>
44
45description18=<p>For example, the following shows three lines from the subject hierarchy file <a href="_httpcollection_/etc/dls.Subject.txt" target="text">dls.Subject.txt</a>. <pre> "Animal Husbandry and Animal Product Processing" 7 "Animal Husbandry and Animal Product Processing" "Animal Husbandry and Animal Product Processing|Cattle" 7.1 "Cattle" "Animal Husbandry and Animal Product Processing|Other animals (micro-livestock, little known animals, silkworms, reptiles, frogs, snails, game, etc.)" 7.2 "Other animals (micro-livestock, little known animals, silkworms, reptiles, frogs, snails, game, etc.)"</pre></p>
46
47description19=<p>These three lines define one top level bookshelf (at position 7), titled "Animal Husbandry and Animal Product Processing", with two bookshelves underneath it, titled "Cattle" and "Other animals (micro-livestock, little known animals, silkworms, reptiles, frogs, snails, game, etc.)" respectively.</p>
48
49description20=<p>In this case, the first strings (and therefore the entries in metadata.xml files) contain the entire hierarchy values. Levels in the hierarchy are separated by "|". They could be used directly by a <i>Hierarchy</i> classifier without the use of the hierarchy file. However, then the entries would be ordered alphabetically, not in the special order defined by the file.</p>
50
51description21=<p>The <a href="_httpcollection_/etc/dls.AZList.txt" target="text">dls.AZList.txt</a> hierarchy file used by the titles classifier contains a similar structure. Ordinarily, a titles browser would use a <i>List</i> (or <i>AZList</i>) classifier. In this case, we want to predefine the A-Z groupings, and include a separate entry for periodicals, as can be seen <a href="?a=d&cl=CL2.7">here</a>.</p>
