====== Warning ======

This is a 2008 work-in-progress page for NancyDru, fgm and eafarris, to update http://drupal.org/node/266511 but never completed at the time. In 2011, update [[g2/choosing|Choosing a glossary module]] instead.

====== Features checklist ======

<html>
<h3><a name="glossary-features-checklist"
 id="glossary-features-checklist">Features checklist</a></h3>

<p><a href="http://drupal.org/project/glossary" title="Glossary">Glossary</a> and 
  <a href="http://drupal.org/project/g2" title="G2 Glossary">G2 Glossary</a> 
  are both targeted to sites needing a glossary section. However, the modules are quite different, targeted to different types of glossary needs, and once you choose one, it will take a significant amount of work to switch to the other one after the fact, so the current maintainers of the two modules have set up this page to help you choose which module you should probably be using, or if you should really write your own.</p>

      <p>Glossary uses Taxonomy to define its terms, allowing definitions to be used as tags for existing nodes.</p>

      <p>For example, 
        <a href="http://drupal.org/project/taxonomy_image">Taxonomy Image</a> 
        may be used to show images for the terms and 
        <a href="http://drupal.org/project/taxonomy_delegate">Taxonomy Delegate</a>

      <p>G2 uses Node to store its terms.</p>
      <p>This allows access control, attachment uploads, commenting, content tagging, revision control, and integration will the vast number of node-related modules.</p>
      <p>Extensibility is directly available from core for G2 content through the extensive core hook system for nodes. Control is available at the individual field level, and includes editor-only information, which is required in publishing situations.</p>
      </td>
    <td>
      <p>Glossify uses Node to store its terms.</p>
      <p>This allows the wide range of contributed modules to add functionality to terms: Adding fields via <a href="http://drupal.org/project/cck">CCK</a>, defining views with <a href="http://drupal.org/project/views">Views</a>, access control, image handling, tagging via taxonomy, etc.</p>

====== Common features ======
<html>
<h3><a name="common-glossary-features">Common features</a></h3>

<p>Glossary and G2 modules work as a Drupal input filter applying to content depending on its input format. These filters are cacheable for performance reasons. Glossify does not provide an input filter. Rather, glossify marks up content on output.

<p>Since the glossary and G2 filter content, the first time a piece of content is shown, there will be a small delay while the filtering is done. The filtered content is then cached, so the next time, the filtering is unnecessary and the delay does not occur. Glossify does not filter, so there is no delay when the content is submitted. Glossify's delay is incurred when content is viewed.</p>

<h3><a name="g2-advocacy">G2 advocacy</a></h3>

<ul>
  <li>Explicit linking to terms with dfn elements:
    <ul>
      <li>limits system workload</li>
      <li>allows invisible marking of entries made of other entries. Think: XML-RPC, points to XML and to RPC with glossary.module and various wiki filters, but can point to "XML-RPC" with G2. Wrapping XML-RPC in quotes is necessary to allow linking to this entry in glossary, but the quotes remain visible, degrading the UI.</li>
      <li>allows redactor-level choice of:
        <ul>
          <li>whether to link to an entry: Glossary typically links if the term matches, which is not always meaningful ("and" can be present in a glossary and you don't want "and" to be linked from in all nodes on the site).</li>
          <li>where to link to an entry: glossary allows only a predefined set of positions (first, last or all matches).</li>
          </ul>
        </li>
      </ul>
    </li>
  <li>Single glossary: multiple glossaries were not necessary to OSInet, which funded development</li>
  <li>Optimization for large glossaries: this is the need expressed by OSInet, which funded development, to support its 5000+ term glossary of computing, for which glossary.module, even when coupled with flexinode or early CCK to bind blob content to terms, was not really efficient enough</li>
  <li>Using custom node type (g2_entry in g2.module) allows large definitions, with the complete drupal feature set for nodes. At the time of Drupal 4.7, neither flexinode not CCK were a reasonable choice for a generic module</li>
  <li>Manual alphabar maintenance: large glossaries will most of the time use all available initials, so the processing cost of maintaining it is not justifiable</li>
  </ul>

    <li>Related terms link to each other.</li>
    <li>Synonyms will filter the same.</li>
    </ul>
  </ul>

<p>Within the glossary display, each term may be followed by a link that will initiate a search for the term, if the search module is enabled. For those who have the proper permission, there will also be a link to edit the term itself.</p>

<p>The type of glossary indicator that is used is specified for each input format, so, for example, "Filtered HTML" may use a superscript type of indicator, while "Full HTML" may use a hovertip. Additionally, each input format also selects which vocabularies are to be used. So one may, again for example, specify that "Filtered HTML" filter for Bible verses, while "Full HTML" filters for technical terms.</p>

<p>Using terms (glossary.module) allows definitions to be bound to custom nodes instead of being nodes on their own</p>

====== Glossify advocacy ======
<html>

<h3><a name="glossify-advocacy">Glossify advocacy</a></h3>
<p>Glossify aims at simplicity. Its code is small, its options are few, and its job is straightforward. Glossify looks at content before it is output, finding and marking up any content that is a title of another piece of content, and links the title to the entry. It does not provide an input filter, nor does it generate a landing page of entries.</p>
<p>Since glossify uses nodes as its entries, the vast customization that Drupal core and contrib offers to nodes are available to glossify entries. They are not limited to entry and definition pairs, but can include other fields via the Content Construction Kit. Lists and blocks can be created with Views. Entries can be classified with taxonomy; they can be themed with PHPtemplate or other theming options.</p>
<p>Glossify has options to limit the content types used for entries and the content types it will look through, and has three different display options for showing what terms have been referenced in the content:</p>
<ul>
<li>The title can simply be linked to the entry. This is wiki-like. The link includes a class for styling via CSS.
<li>The entry can be shown via a hovertip, if the appropriate module is available. These can be themed via Drupal's theming mechanism.
<li>A "referenced terms" area can appear underneath the main content. This section is available for theming via Drupal's theming mechanism.
</ul>
