Once you have opened the Metadata Editor, you have full access to all the editing options relating to the pagination, structure data and metadata of the digitised material. The Metadata Editor is divided into a number of sections.

The grey-shaded area on the left of the screen contains the structure tree, where you can see in hierarchical form all the structure elements that have already been obtained from the source material. When you select a structure element, it will appear in bold in the tree view. For each structure element, the descriptor is based on the type chosen for that element.

Click on the icon just in front of the structure element to expand or collapse individual sections of the structure tree. If you hold the cursor over the small symbol next to each structure element, you will see a pop-up with further details of that structure element without having to open it.

The right-hand side of the Metadata Editor gives you an overview of the individual digital images that form part of the current process together with the number of pages, the current magnification level, the currently displayed image number and information about which derivative of the available digitised material you are currently viewing.

Page navigation

You can move between individual pages using the Forward and Previous links just above the image. You can also move quickly to the previous and next images by selecting them directly.

The current page is shown in the middle of the page range with the previous and next two pages on each side (provided they are available for display). Clicking on any of the pages will take you directly to the corresponding scanned image. Goobi also features a number of keyboard combinations for repeated navigation between different pages of the source material.

Keyboard combination for navigating between images in the Metadata Editor

Using these keyboard combinations allows you to move quickly and easily through the digitised material, even over large areas. Another navigation option allows you to move directly to a specific image by entering that image number in the Go to image box and pressing return. Goobi will then automatically display the requested image.

Zoom

In addition to all the above navigation options, you can also change the way Goobi displays the scanned image. To do so, just click on either magnifying glass symbol below the page navigation bar to increase or reduce the magnification/zoom level. The current magnification is shown between the two magnifying glass symbols. If you want to select a particular level of zoom, simply click between the two magnifying glass symbols, enter a figure and press the Enter key to confirm.

Rotation

Goobi also allows you to rotate the image in 90 degree stages to view information that can only be read in landscape format. To do so, just click on the arrow pointing to the right to rotate the image clockwise and on the arrow pointing left to rotate the image anti-clockwise.

Selecting the image folder

Underneath the image you will find an option to select from different derivatives of the image (where available). In the drop-down list entitled Folder, Goobi lists all the image folders linked to the currently selected process. For example, if you already have a number of derivative images for a specific process (e.g. master images, scaled or compressed versions of images or derivatives with a different tone such as bitonal images), you can switch between these derivative images simply by selecting the corresponding folder.

Choosing representative image

Within the METS Editor you can specify a particular image that can be used to represent the entire work. This is usually the title page. Most digitisation portals (e.g. Europeana, ZVDD, VD18) and the Goobi viewer use the first image in the METS file as the representative image, unless a different image has been specifically chosen for that purpose.

In order to specify the representative image, first select the required image from the available list. Click on the corresponding icon make this the representative image. Within the METS file, the selected image will now have the attribute USE=“banner“.

<mets:file ID="FILE_0002_PRESENTATION" MIMETYPE="image/tiff" USE="banner">
     <mets:FLocat LOCTYPE="URL"     
     xlink:href="file:///opt/digiverso/viewer/media/BV041228853/00000003.tif"/>
</mets:file>

Goobi offers a wide range of functions that simplify the task of working with structure data and metadata. These options can be found in the top menu bar and at the right-hand edge of the structure tree pane in the Metadata Editor.

Functions in the top menu bar

The following functions are available from the top menu bar. The corresponding icons can be found on the right-hand side of the bar.

Validation

At any time while you are working with the Metadata Editor, you can use the Validate option to check whether you have complied with the rules provided by Goobi for the structure data and metadata. These rules are defined individually for each project by the Goobi administrator. Before closing the step you are working on, Goobi will conduct a further validation check. If this validation fails, Goobi will not let you close the task. It is therefore advisable to perform regular validation checks in the Metadata Editor to ensure that you have complied with the rules. If you click Validate and Goobi then determines that your metadata and structure data do not comply with the established rules, it will display an explanatory warning message to that effect.

Fixed image

By choosing this function you can prevent the image from scrolling in the Metadata Editor when you are dealing with long lists of metadata or during the allocation of pagination sequences. If you activate this function, the selected image will remain in place on the right hand side of the window together with its navigation bar and the zoom options, even if you scroll up or down on the right of the Metadata Editor.

Settings

This menu bar icon provides several options for additional settings. Simply click the icon to display the available functions.

Save

The Save option allows you to save your work in the Metadata Editor at any time. You should always click on this button when you want to make sure your data cannot be lost.

Exit the METS Editor

Click this menu bar icon to exit the METS Editor. You then have two options.

The Exit option exits the Metadata Editor without saving your work, so you should usually ensure that you save your data before selecting this option. This function can also be used, for example, to exit the Metadata Editor without having to save your work in the event that you unintentionally delete or change the data.

The option Save and exit saves all your work and closes the Metadata Editor. Goobi will then return you to the screen from which you launched the Metadata Editor. If you accessed the Metadata Editor from My tasks, for example, you will find yourself back in that area. If you launched the Metadata Editor from the Processes area, selecting Save and exit will automatically return you to the same point in that area.

Additional settings

If you select the menu bar icon Settings, Goobi will display a drop-down list containing several additional functions.

Display the hierarchical level in the structure hierarchy

Click on this function to display information about the hierarchical level of each structure element in the structure tree on the left. This function is particularly useful in cases where the hierarchy of the structure tree contains many levels. An indication of the hierarchical level can help you determine which level you are currently viewing.

Fully collapse the structural hierarchy

Using this function, you can switch between the fully expanded and fully compressed versions of the structure tree on the left hand side of the Metadata Editor. This allows you to fully expand even the most complex structure trees with a single click without having to click and expand each section within the tree individually.

Hide image / Show image

You can select the Hide image option at any time to prevent the image from being displayed. Conversely, the Show image option causes the image to be shown again after being hidden.

Reset pagination completely

This option allows you to recommence pagination. You may wish to use this function to reset all the pagination data and start indexing the pagination sequences again from the beginning.

Show physical structure tree / Show logical structure tree

This function allows you to work with the physical structure tree rather than the logical structure tree. This allows you, for example, to record metadata for individual pages or edit metadata stored in the physical metadata area.

Functions available at right-hand edge of the structure tree pane

The structure tree pane contains a number of additional icons/functions that can be used to modify the way the structure tree is displayed.

Link the image with the selected structure element

The function gives you an option to link the structure tree on the left of the Metadata Editor to the image. If this function has been activated, the image display will change to the start page of the structure element you have selected in the structure tree.

Show main title in the structural hierarchy

If you activate this function, Goobi will display the names given to individual structure elements directly within the structure tree. This may give you a better overview, e.g. to help you locate chapters by their name in the structure tree.

Display the assigned pages in the structure hierarchy

Select the Tree page number to display the page ranges allocated to each structure element in the structure tree on the left. The first and last page of the range will appear in brackets next to each structure element. Each page range displayed contains the image number and the page label (printed page number).

Print this page

Select this icon if you wish to print out the structure tree.
