Adding metadata to an image in Greenstone Digital Library
Open Greenstone by going to Start -> All Programs -> Greenstone Digital Library Software v.2.8 -> Greenstone Librarian Interface. Three windows will open up, and the last window to open will begin searching for any open collections. Any open collection will be listed on the title bar of the window. If no collections are open, or if a collection other than the one you wish to work with is open, click File -> Open and select the correct collection. Another window will open with two sections. The top section shows the list of available collections, and the bottom gives a description of each collection as the collection is selected. Click on the collection you wish to open and click the OK button.
Six tabs are shown below the main toolbar in the Greenstone window: Download, Gather, Enrich, Design, Create, and Format. The window opens in the Gather tab. In Gather, there are two sections, the left section shows a list of folders from which you can gather files; the right section shows the files in the open collection. In the left section, navigate to the images you scanned that should be added to the collection. Click once on the file or folder to highlight it, and then drag it into the right section of the window. This transfers the files into the Greenstone collection.
Once the files have been added to the collection, click on the Enrich tab to add metadata to each image. The Enrich window also has two sections, the left, which lists the images in the collection, and the right, which lists the metadata fields for each image. The metadata fields consist of the fifteen Dublin Core elements, plus an added sub-element which gives the scanning date of the image. Two other Dublin Core elements are not listed in the right column, but are extracted automatically from the image by the Greenstone software.
To add metadata to the photo, click on the name of the image in the left section, then click on any element in the right hand section. The bottom section of the window will display all of the entries that have been added to that particular element in the collection. If the correct information is in the list, select it in the bottom section and it will be automatically entered into the field. If none of the choices on the list are appropriate, type the information directly in the field.
This chart explains the content for each metadata field. Use the thesaurus that follows these instructions to choose names, locations, subjects, activities, organizations, departments and programs to add to the Subject and Keywords field. The thesaurus is divided into three sections: first, a list of descriptive terms for subjects and activities, second, a list of academic and administrative departments, and organizations, and third, a list of geographic place names.
After the fields are filled in, click on the next file, and repeat the process. After all images have been completed, click File -> Save, then close the Greenstone Librarian Interface. Note that it is the jpeg image that is loaded onto the database.
HELPFUL “how to” NOTES:
Correcting images in Photoshop:
Yearbook images: click on “filter: tab; go to “Noise”; open “dust and scratches: and increase radius to 3 pixels (threshold stays at 0 levels). Use 300 dpi for yearbook images.
Compressing files in Adobe: click “documents” and then “optimize”. Do this after OCR.
