====== Collection Grouping in Greenstone 3====== You can group collections in Grenstone 3. This can clean up the home page if you have a lot of collections, as a group will have a single icon on the home page. CLicking it takes you to a home page for the group: only those collection in the group will be displayed here. Grouping is controlled by the groupConfig.xml file, found in a site folder alongside the siteConfig.xml file. For example, in /home/user/greenstone3/web/sites/localsite/groupConfig.xml. By default, there are no groups. Add hierarchy and groupDescriptions elements to add groups to your library. Describe your structure inside a hierarchy tag as shown in the examples below. Hierarchys can contain groups and/or collections. Groups can contain other groups and/or collections. The order they are listed is the order they will appear on the home page. Describe your groups in groupDescriptions element as shown in the example below. Without a matching group element in groupDescriptions, a group will display its name. If a collection is not mentioned in the hierarchy or as part of a group it will be listed on the main home page after the specified groups and collections. Example 1: this example puts a few Greenstone demo collections into some groups. The home page will display the demo group plus any unlisted collections. The demo group home page will display its two subgroups; their home pages will display their list of collections. Demo Collections Collections for demonstration purposes, provided by the Greenstone project.

Demonstration collections that come with the Greenstone binary. Documented Example Collections These documented example collections describe how they are constructed on their about page. Useful for learning about different Greenstone features. Collections that describe how they were built. Example 2: If you want to put your collections into a specific order, you can list them in the hierarchy. Any unmentioned collections will be listed at the end. This example has no groups, but is a way of specifying which order you want the collections to appear on the home page.
