System Requirements and notes
The HTML version of the MOA2 viewer currently only runs in browsers that
accept cookies. Cookies are used solely to transmit a Session id assigned
to a session on startup.
The MOA2 HTML Viewer has been tested with Netscape Navigator 4.7 and with
IE 5 on the Windows95 platform and with IE5 on the Mac platform. Please
features used in the viewer.
To get a feel for all of the features in the demonstration version of the
HTML-based MOA2 document viewer, follow these steps:
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
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
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.
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.
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.
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.
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 21st" 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.
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).
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
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.
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
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.
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.
Select an alternate view for either Resource frame. Note that you
can combine any two manifestations you wish.
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.
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.
Marc Record Lnk. Clicking on the Marc Record link brings up the
record for the Breen Diary in UCB's Pathfinder catalog.
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.
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.
XML Source Link. Clicking on the XML Source link brings up the XML
code for the source XML document.
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.
