Datastreams
-
Static 24-bit color or 8-bit grayscale JPEG preview,
120x120 pixels constrained
-
Static 24-bit color or 8-bit grayscale JPEG screen,
800x600 for documentary images, or 650-850 pixel width range as appropriate
to achieve readability on screen
-
Mr. Sid encoded max, with 2 to 10 levels as
appropriate for the size of the image

uvaHighRes Image Content Model
- uvaDefault Disseminator / uvaDefaultHighRes Mechanism
- getPreview – returns the thumbnail resolution of the image.
- getLabel
- getDescription
- getFullView(pid)
- getDefaultContent
- uvaMeta
- getDescMeta
- getAdminMeta
- getDC
- viewDescMeta(style)
- viewAdminMeta(style)
- viewDC(style)
- uvaImage Disseminator / uvaImageHighRes Mechanism
- getPreview – returns the thumbnail resolution of the image.
- getScreen - returns the screen-sized resolution of the image.
- getMax - returns a larger image to set parameters.
- getImageViewer - returns a larger image within the ImageViewer
Applet.
- uvaDownload Disseminator / uvaImageDownload Mechanism
- getDownload – initiates a download of the screen datastream
through the browser.
- uvaOKI
- getAssetDefs (childPid, parentPid)
- Other
- getDeliveryMaster - returns the Mr. Sid master or a page describing
where the master is located. For Phase 2, returns a statement
describing the offline location of the master. The non-Fedora
version does NOT exist in Phase I; Fedora-ized version will require
writing a new script to handle this behavior. Meant to return
the Mr. Sid master or a page describing where the master is located.
Still to be implemented?
Recommendation:
The getDeliveryMaster behavior will point to an element in
the administrative metadata where the offline location of the Delivery Master
is located, once that element is in use.
