Editing metadata sets

GEMS (Greenstone Editor for Metadata Sets) can be used to modify existing metadata sets or create new ones.

Running GEMS

  1. Start the Greenstone Editor for Metadata Sets (GEMS):

    Start → All Programs → Greenstone Digital Library Software → Greenstone Editor for Metadata Sets

  1. A list of all the available metadata sets is shown on the left hand side. Explore these metadata sets, and see what elements belong to each set. Double click on a folder icon to open the set. A list of elements will be displayed.

Creating a new metadata set

  1. In this exercise, we will create a new metadata set. In order to save time, we will base it on an existing one: Development Library Subset. From the File menu, select New... (FileNew...). A popup window appears: Add Set. Fill in the fields. Use "My Metadata Set" for the Name, "my" for the Namespace, and select "Development Library Subset Example Metadata" from the Inherit from Metadataset: drop down list. Click <OK>.

  1. A folder for My Metadata Set will appear in the metadata set list on the left. Double click the folder icon to see what elements it has. Since it was based on the Development Library Subset metadata set, it contains all the elements from that set.

Adding a new element to a metadata set

  1. Right click on the My Metadata Set (my) item in the list of metadata sets, and choose Add element from the menu that appears. In the popup window, type "Category" for the Name, and click <OK>. The new element will appear in the list.

  1. Right click on the my.Category element and select Add attribute from the menu. Select definition from the Name drop down list, and enter "The category this resource belongs to" in the Values box. The GLI uses the element definitions when displaying information about a metadata set.

  1. Save the new metadata set by FileSave, then close the GEMS by FileExit.
