Tutorial/Features checklist

1. Select a document from the MOA2 Document Chooser List. When you activate the HTML-based MOA2 Document viewer from the MOA2 home page, a list of the available MOA2 documents will display. Select the Patrick Breen Diary (the very first document on the list) for use in this tutorial. Document will appear in a the MOA2 Document viewer in a separate browser window.
2. Notice the "Left Frame:" and "Right Frame:" Display Option boxes. Two roll-down option boxes appear at the top of the right hand frame of the document window. The left option box (labeled "Left frame:") controls what appears in the left-hand frame of the window. The right option box (labeled "Right frame:") controls what appears in the right-hand frame of the window. The available view options for both frames are discussed below.
3. Explore the Contents View. When a document is first selected, the viewer displays a "Contents" view by default.. This view has two frames: a Contents frame on the left and a Resource frame on the right. The Contents frame shows the document’s hierarchical structure in the form of a tree with expandable/collapsible nodes. The Resource frame displays a single resource (image or text transcription unit) associated with the selected node of the document hierarchy.
1. Select different entries from the Contents frame. Click on various entries in the left-hand Contents frame. The corresponding page image will appear in the right-hand frame.
2. Expand a contents node. The final entry in the Contents frame for the Breen Diary has a blue arrowhead icon  next to it (This entry is labeled "Letter by George McKinstry…"). The arrowhead icon indicates that this entry has sub-entries. Click on the icon to expand the node and view the sub-entries. Click on the icon (which now points down instead of to the right) again to collapse the node.
3. Navigate in the Resource frame. Note that the right-hand resource frame has three buttons at the top: First, Next, and Prev. Click on Next to view the next resource (image or text transcription unit) in sequence. Click on Prev to view the previous resource. Click on First to view the resource associated with the root of the document hierarchy. Note that as you move forwards or backwards in the right hand frame, the corresponding entry in the Contents frame is highlighted. The Contents frame will scroll as necessary to keep pace with your movements in the right-hand frame.
4. Select alternate resource views (manifestations) in the Resource frame. At the top of the Resource frame there is a roll-down view selection box labeled "This frame: ". Click on the arrow to the right of this box to view the available options. An entry appears for each alternative version (or manifestation) of the current resource that is available. These are followed by an entry for activating the Administrative metadata for the Resource on display. To explore this part of the Resource frame, select the entry for "sat 21^st" from the Contents frame. A medium-sized jpeg image displays in the right-hand Resource frame, and the "This frame: " selection box has six entries: one for a gif; one for a medium resolution jpeg (the current view); one for a higher resolution jpeg;  and one entry for each of three text transcription units for entries appearing on the diary page. Note that the currently active (or selected) view is the one that appears in the "This frame: " selection box. Click one of the other entries that appear in the selection list to activate an alternative view in the right-hand Resource frame. Once you have selected an alternative view, its format will remain the default until another view is selected, or a new document is activated.
5. Explore a thumbnails view. To the left of the "This frame: " selection box appears a second selection box labeled "Left frame: " As noted above, this selection box controls what appears in the left-hand frame. Click on the arrow to roll down the left frame view options; note that two sets of thumbnails are offered in this list. Select the "Entry thumbnails" option, and a thumbnails view will appear. This consists of a Thumbnail frame—a scrolling "box" of thumbnail images—on the left and a Resource frame on the right. (This view will be most useful when there are pictorial images--for example, in the case of a photoalbum).
6. Select different thumbnails for viewing at higher resolution. Click on a thumbnail in the left-hand frame. The current default manifestation of the selected thumbnail image will display in the right-hand Resource frame.
7. Navigate in the thumbnail frame. The thumbnails are delivered in groups of ten. You can select the next set of ten thumbnails by clicking on the "Next set" button at the top of the Thumbnail frame. You can select the previous set of thumbnails by clicking on the "Prev set" button. Note that when you jump to the next or previous set, the Resource frame displays a resource corresponding to the first thumbnail in the set.
8. Navigate in the Resource frame. As you move forwards or backwards in the right-hand Resource frame, the contents of the Thumbnail frame will keep pace with your movements. In other words, the next or previous set of thumbnails will be activated for you as you move beyond the limits of the current set in the course of "Next" or "Prev" movement in the right-hand frame.
4. Explore a combination view. Roll down the "Left frame: " options. Note that an entry appears for each available manifestation of the current resource. Select one of the options that is prefixed "text: " to activate the text transcription for one of the entries appearing on the currently active diary page. A combination resource view consisting of two side-by-side Resource frames comes up. A scrollable text transcription positioned at the selected diary entry appears in the left-hand frame alongside the page image already active in the right-hand frame.
1. Navigate forwards or backwards in the right-hand Resource frame. As you move forwards or backwards in the right-hand Resource frame, the view in the left-hand Resource frame will keep pace.
2. Select an alternate view for either Resource frame. Note that you can combine any two manifestations you wish.
5. Try the full screen option. Note that in the right-hand Resource Frame, a "Full Screen" option appears next to the "This frame" option box. Clicking on this brings the resource (page image or text transcription) up in separate, unadorned browser window. This enables the image or text transcription to be viewed full-screen. Dismiss this window to return to the viewer.
6. Explore the "See also" links in the Link frame. On the lower left-hand side of the browser window a Link Frame appears offering several "See also" links. Try each of the offered links.
1. Marc Record Lnk. Clicking on the Marc Record link brings up the record for the Breen Diary in UCB's Pathfinder catalog.
2. Finding Aid Link. Clicking on the Finding Aid link brings up the Finding Aid (EAD) for the Breen Diary in the Online Archive of California at the California Digital Library.
3. Administrative Metadata Link. Clicking on the Administrative Metadata link brings up the Administrative Metadata for the resource appearing in the right-hand frame. In the case of images, administrative metadata for both the current derivative image and the master image is included.
4. XML Source Link. Clicking on the XML Source link brings up the XML code for the source XML document.
7. Select another document from the MOA2 Document Chooser browser window. Go back to the browser window displaying the MOA2 Document Chooser. Available documents are presented in groups of 20.  Use the "Next 20" and "Prev 20" buttons at the top of the chooser window to navigate through the list.  You can select any document for viewing by clicking on its entry in the MOA2 Document Chooser list.  Document will appear in the MOA2 Document Window already active.
