We can use this extracted location metadata to display the location data in these images more meaningfully. Move to the <b>Enrich</b> pane, expand a folder, select an image and scroll through its extracted metadata to find several pieces of metadata specifying Latitude and Longitude information: ex.LatShort, ex.Latitude, ex.LngShort and ex.Longitude.</Text>

     5255<Text id="dl-c1">Greenstone3 is built on the idea of sites and interfaces. <b>Sites</b> mainly contain <i>content</i>, i.e. they contain collections, which, in turn, contain documents and associated metadata. Sites are a convenient way to group collections. <br/><br/></Text> 
     5256<Text id="dl-c2"><b>Interfaces</b> dictate the presentation -- e.g. the HTML, CSS, Javascript, etc. used to present the content. You can have multiple sites and interfaces. <br/><br/></Text> 
     5257<Text id="dl-c3"><b>Libraries</b> combine content and presentation. To define a library, you select the site and the interface you want it to use. And, of course, you can have multiple libraries, and each site and interface can be used multiple times.  <br/><br/></Text> 
     5258<Text id="dl-c4">In this tutorial, we will become familiar with <b>web.xml</b>, where we can define new libraries; create a new site; add an interface; and define a new library.</Text>

If you continue to scroll down, you will see several other library servlets defined.

To do this, in the <b>Greenstone Server</b> window, go to <Path>File &rarr; Settings...</Path> and select your library (for example, <b>rand</b>) from the Servlet dropdown menu.

First, any changes you make in the GLI are <b>collection-level</b>, which means they will be the consistent for this collection no matter what library you are using. However, changes may only take effect <i>immediately</i> in the current library. The server may need to be restarted for the changes to appear in other libraries. Second, switching between servlets -- or viewing a collection in a library other than the one currently being used by the GLI -- can create a lock on files in a collection, which will cause an error during collection building. To avoid this, if you use multiple libraries after launching the GLI, <b>restart the server</b> before rebuilding a collection.

     5804</Comment> 
     5805<Text id="ni2-14">First look at the collDescription template. It creates a header that links to the collection's about page (<Format>&lt;h2&gt;&lt;a href="{$library_name}/collection/{$collectionFolder}/page/about"&gt;&lt;xsl:value-of select="$collectionName"/&gt;&lt;/a&gt;&lt;/h2&gt;</Format>). Then, if there is an About page image for the collection, this is displayed. Finally, if the collection has a description (<Format>&lt;xsl:when test="$collDesc"&gt;</Format>), it will display this description. Otherwise, it will display the a generic sentence stating the collection's name and how many documents it contains.</Text> 
     5806<Text id="ni2-15">Now, let's look at the collectionsList template. Basically, for every collection in the library (<Format>&lt;xsl:for-each select="./collectionList/collection"&gt;</Format>), it is calling the collDescription template, i.e. doing everything explained in the previous paragraph. However, the CSS we are using requires that our div's alternate between class "fl_left" and class "fl_right" or the page won't display correctly. So, if the collection is an odd number in the list (<Format>&lt;xsl:when test="position() mod 2 = 1"&gt;</Format>), the collection description will be in a  <Format>&lt;div class="fl_left"&gt;</Format>, otherwise (i.e. when it is an even number in the list) the collection description will be in a  <Format>&lt;div class="fl_right"&gt;</Format>.</Text>

     6062<Text id="ni3-16">Let's take a look at the <b>navBar</b> template and try to understand what it's doing. First, it's checking to see if the page is a collection page (<Format>&lt;xsl:when test="page/pageResponse/collection"&gt;</Format>). If so, it will create a link back to the home page (<Format>&lt;li&gt;&lt;a href="{$library_name}"&gt;Home&lt;/a&gt;&lt;/li&gt;</Format>) and to the current collection's about page.</Text> 
     6063<Text id="ni3-17">Then, if there are 3 or fewer browsing classifiers, they will each become a link on the navigation bar. If there are more than 3 browsing classifiers, then they will be made into a dropdown menu under the heading "Browse". (If there are too many links in the navigation bar, they will start to overlap.) Finally, if there are any search types, they will be in a dropdown menu under the heading "Search". In addition, it adds the attribute "class=active" to the link for the current page so that it will be colored differently. </Text>

     6248<Text id="ni3-29"> However, the <b>help.xsl</b> file in <b>default</b> is looking for a file called <Format>interface_&lt;interface-name&gt;2.properties</Format>. So, when the <b>default</b> interface is being used, it will look for the file <Format>interface_default2.properties</Format>, which does exist. But since our library is using the <b>perrin</b> interface, it is looking for the file <Format>interface_perrin2.properties</Format>, which does <i>not</i> exist. There are a few different solutions to this. The quickest solution at the moment is to create an <Format>interface_perrin2.properties</Format> file so that the English values will display.</Text>
