The following instructions are by Georgy Litvinov.

Requirements: a Greenstone3 installation, a collection to test it on.

1. Run the Greenstone 3 server (gs3-server) and visit your digital library home page in the browser. If you have installed Greenstone 3 on your PC, the URL to visit would be http://localhost:8383/greenstone3/library or http://127.0.0.1:8383/greenstone3/library

2. You need to be logged in to edit your collection. To do so when using the default Greenstone 3 library interface, you'd click the Login button at the top right of the home page. (For the half-tone interface, click on the down arrow at the bottom of the home page to View More options, and then follow the Login link). Use the username and password you created during installation. The default is admin for both. If you haven't change the defaults, you can do so by running ant config-admin from the command line.

3. You need to enable the document edit mode. To do so, click on the button with your account name at the top right of the page (where the Login button was). From the drop-down list, choose Enable edit mode.

4. Open the document you wish to edit. You can do this by using Search or to locate your document, or you can simply open the document after Browsing to it with a collection classifier.

5. With a document open, click on the Edit content button to the right.

6. You'll now be you able to edit the internal content of your document much like in your favourite text editor. Click on anywhere in the text body of the document to see a cursor to start editing the content.

7. You can modify metadata by pressing edit metadata button above the document body.

8. If you want to add new metadata, fill in the field underneath the metadata table with a new metadata name and click on the button Add new metadata. Your new metadata entry will appear at the end of the metadata table. Then enter a value for your new metadata entry.

9. As you may know, you can use hierarchy classifiers in your collections. To add a document to the hierarchy classifier, you need to add a metadata entry just as you did in step 8 above, but with a metadata name used by the hierarchy classifier. To choose the hierarchy position you then want to assign to your document, click on the value cell. To the right of the metadata table, you will see a flyout menu from which you can select the hierarchy position. You can also manually enter the hierarchy position as metadata value. In that case, you will see suggestions indication a position you can choose from.

10. To save your changes, just click on the Save and Rebuild button and wait for the build to complete.
