Preliminary high level use cases for MOA2 documents
Summary of desired navigation between levels. In the best of all
possible worlds user would be able to navigate between collection/item
level MARC records, finding aids, and the various levels of an MOA2
object as follows:
<paraindent><param>out</param>1) From collection level MARC record to
finding aid to individual MOA2 object.
2) From collection level record to individual MOA2 object (if no finding
aid available? This is in my notes but I am not clear on the
circumstances).
3) From MARC record for individual MOA2 object to MOA2 object (when no
finding aid is available).
4) From any level of individual MOA2 object to corresponding collection
level MARC record or item level MARC record (if item not part of
collection).
5) From any level of MOA2 object to highest level of corresponding
finding aid.
6) From top level of MOA2 object to specific page image (if page images
are present).
7) From top level of MOA2 object to specific page level text
transcription unit (transcription units would often not correspond to
pages and could cross page boundaries).
8) From top level of MOA2 object to specific pictorial image (image of an
individual photograph, for example)
9) From specific page image of MOA2 object to specific corresponding
section of finding aid.
10) From specific page level text transcription unit of an MOA2 object to
specific corresponding section of finding aid.
11) From individual pictorial image of MOA2 object to specific
corresponding section of finding aid.
12) From MOA2 object to other related MOA2 objects based on common
metadata elements.

<paraindent><param>out</param>1) Select default page image and pictorial
image resolutions (for current document) from available resolutions
2) Select active view(s) from available views.
</paraindent><paraindent><param>left,out</param>a) Available views could
include the following depending on the content of a particular MOA2
object:
</paraindent><paraindent><param>left,left,out</param>i) table of
contents/document hierarchy view
ii) document page image view
iii) document text transcription view
iv) individual pictorial image view

thumbails)
</paraindent><paraindent><param>left,out</param>b) Views could be active
individually, or simultaneously in any appropriate combination. For
example, any or all of the following views could be simultaneously
active: table of contents/hierarchy, document page image, document text
transcription, individual pictorial image.
</paraindent>3) Select default printing resolution.
General MOA2 viewer capabilities. User can:
<paraindent><param>out</param>1) View collection of all pictorial image
thumbnails associated with MOA2 object. (If thumbnails are
available).
2) Select individual pictorial images for viewing at higher resolution
from collection of thumbnails.
3) View collection of all page image thumbnails associated with MOA2
object. (If page image thumbnails are available).
4) Select individual page images for viewing at higher resolution from
collection of page image thumbnails.
5) View document table of contents/document hierarchy if available.
6) Select page level entry point into document from document table of
contents/document hierarchy.
7) View page image as selected from document table of contents/document
hierarchy.
8) Move through page images from any starting point. (Starting point
could be established by selecting an entry from the document hierarchy,
or by selecting a page from a collection of page image thumbnails). User
can move sequentially through MOA2 object page images as follows:
</paraindent><paraindent><param>left</param>a) Next page
b) Previous page
c) First page
d) Specific page (by absolute page number)
</paraindent><paraindent><param>out</param>9) Select pictorial image
level entry point into MOA2 object from the document table of
contents/document hierarchy.
10) Select pictorial image level entry point into MOA2 object by asking
to view pictorial images associated with the currently active page.
11) Select pictorial image for viewing by clicking on portion of page
image on which it appears.
12) View pictorial image associated with MOA2 document as selected in
case 9) , 10) , or 11) above.
13) View stereographic images in 3D.
14) Move through pictorial images from any starting point. (Starting
point could be established by selecting a pictorial image from a
collection of pictorial image thumbnails, by selecting a pictorial image
from the document hierarchy, or by asking to view pictorial images
associated with the current page). From a given pictorial image movement
could be to:
</paraindent><paraindent><param>left,out</param>a) Verso of current
pictorial image (if available and identifiable).
b) Next pictorial image. (If viewing pictorial images associated with
specific page should "next image" movement stop at last pictorial image
associated with page? Or continue on to next pictorial image in the
collection?)
c) Previous pictorial image. (If viewing pictorial images associated with
specific page, should "previous image" movement stop at first pictorial
image associated with page? Or continue on to previous pictorial image
in collection?)
d) First pictorial image for page (if viewing pictorial images associated
with specific page).
e) First pictorial image for MOA2 object.
</paraindent><paraindent><param>out</param>15) View page image or
pictorial image in other available format/resolution. Format/resolution
may either be static or dynamically generated.
16) Zoom in and out on page image or pictorial image; view at 100% .
17) View administrative metadata for page image or pictorial image.
18) Print page image or pictorial image at desired resolution.
19) View page level text transcriptions from starting point selected from
document hierarchy/table of contents. (Page level text transcriptions
would be those associated with page images. However, the text
transcription units would not necessarily observe page boundaries)
20) Move through page level text transcription units as outlined below.
</paraindent><paraindent><param>left</param>a) Next page level
transcription unit .
b) Previous page level transcription unit
c) First page level transcription unit.
</paraindent><paraindent><param>out</param>21) View page image and any
associated text transcription units side by side.
22) Move sequentially through side by side page images/associated text
transcriptions from a given starting point. Movement could be
synchronized or independent.
23) View pictorial image text transcriptions in conjunction with its
associated pictorial image. (Pictorial image text transcriptions would
include transcriptions of writing on the recto or verso of the source
image. My current, and very possibly false, assumption is that it would
not be very useful to allow the users to view and move through
transcriptions of text on individual pictures independently of the
associated pictorial images).
24) Search text in single, currently visible transcription unit (whether
the transcription unit is associated with a page image or a pictorial
image)
25) Search text in all available transcription units (both page level
and pictorial image level: or do users need ability to search these two
categories of transcriptions separately ?)
26) Select entry point into MOA2 object from list of text search results.
27) Move through MOA2 object on basis of text search results.
28) View Administrative metadata for transcriptions (either page image
level or picturial image level transcriptions)
29) Print single transcription unit (either page image level or
pictorial image level transcriptions)
30) Print all page level transcription units.
31) Search text identifying document divisions (that is, the text of the
LABEL attributes associated with divs in the StructMap.). Select entry
point into document from list of search results.
32) Search pictorial images in collection by descriptive and
administrative metadata elements such as photographer, date, etc.
33) Sort pictorial images in collection by descriptive and administrative
metadata elements.
34) Move through pictorial images searched and sorted by
descriptive/administrative metadata in order. May be viewed alone or
together with any associated text transcription units.
35) Submit rights request to rights owners (system facilitated rights
inquiries).
36) Annotate document.
37) View document annotations made by others.
38) Assemble virtual collection of Archival Documents.
39) Enhance/edit screen appearance of images.
