- Subject matter: American Civil
War and Lincoln
- Metadata requirements: MODS
profile
- Currently only two institutions
meet both requirements:
- Library of Congress
- Indiana University
|
7
|
- Built upon the experience with
OAIster and IMLS grant
- Expanded to harvest MODS records
- Including thumbnails, “harvested”
from UIUC
|
8
|
- Developed from OAIster
- Improved interface
- More fields to search
- Language (now human readable!)
- Institution
|
9
|
- Added “dataset” as resource type
- Developed SRU functionality

- Date normalization
- Subject classification /
clustering
|
15
|
- Expose an abstract set of actions that can be delivered on demand for an
object
- Named, typed groups of actionable URIs
- Developed by UVA, Tufts and Northwestern
- New schema developed as a quick, pragmatic way to get started
- Will look at UnAPI, METS and MPEG21
|
16
|
- Asset action packages contain one or more action groups
- Must contain a “default” group
- Can contain any number of other groups
- Action groups contain any number of actions
- Actions are composed of:
- Label: string that could be presented to a user
- Name: machine-readable name for the function
- Type: ideally, a registered content type
- URI: returns the named function
|
17
|
- getActionPackage: returns the current version of the asset definition.
- getPreview: returns minimal view of the resource that can share the
viewing space with other previews.
- getLabel: returns the appropriate string of plain text that can
represent the resource.
- getDCRecord: returns an XML OAI-DC Dublin core record.
- getWebView: returns a view of the resource as a web page.
- getDefaultContent: returns a byte stream of raw content for the
resource.
|
18
|
- getThumbnail: returns a small image that can share the viewing space
with other images.
- getScreenSize: returns an image that assumes the entire viewing space.
- getMaxSize: returns the largest image that will be made available.
- getDynamicView: returns and interactive the image embedded in a web
page; it is intended to provide the image in an interactive setting.
