2. Project Context
•
Started as a collaborative digitization project partnering:
•
University of Illinois at Urbana-Champaig and
•
Herzog August Bibliothek Wolfenbüttel.
•
Resulted in the creation of the Emblematica Online Virtual
Collection.
•
Provides emblem scholars access to about 700 digitized emblem
books and over 18,000 fully described emblems.
•
Desire by emblem scholars for web-based, dynamic methods of
interacting with the emblems is driving the development of digital
tools, including digital annotation tools.

4. Emblem Scholar Annotation Use Cases
•
Generally for note-taking and sharing
•
But also examples of more sophisticated annotation & discourse needs.
•
Three key examples of sophisticated annotations:
•
Comparison of emblems and/or emblem elements (visual juxtaposition of
digital resources) – Annotation of a composite set of targets,
•
Annotation of emblem or emblem elements within their context –
Preservation of annotation contextual elements and
•
Annotations supporting scholarly discourse – Layering of annotations.

8. Example 1:
Important issues – URIs for annotation targets
• One best practices issue is how best to select the URIs of the
targets of an annotation.
– Can use urls, such as those provided by services like djatoka, e.g.,
http://djatoka.grainger.illinois.edu/adore-djatoka/resolver?url_ver=Z39.88-
2004&rft_id=http://emblemimages.grainger.illinois.edu/theatrummortishu00valv/J

e/jpeg&svc.level=5&svc.rotate=0&svc.region=576,2472,1560,1320,
– Can use media fragment identifiers (but this W3C standard doesn’t
seem to be well supported) or
– Can use a source uri plus a selector (as shown in the example)
• But, which of these actually help to co-locate annotations of the
emblems?
– Preliminary consensus is that separating the selector (i.e. the fragment) from the
source URI is the best approach in most cases.

12. Example 2:
Important issues – preservation of annotation scope
•
Preserving the scope of an annotation is important for several
reasons:
•
Allows annotations to be associated with larger bodies of
resources (e.g., an annotated emblem is one of many in a book
of emblems),
•
Allows annotations to be collocated in multiple ways (e.g., can
search for annotations by specific book rather than just specific
emblem),
•
Preserves the meaning of annotations that are context sensitive;
for example, a symbol may have a different meaning depending
on the textual elements of an emblem.

18. Example 3:
Important issues – Separation of body and annotation
•
Why have separate identities for annotation and annotation content?
•
Allows for preserving the identity of the relationship of the annotation body to the
annotation target.
•
Makes the relationship into a distinct web resource with its own set of properties.
•
Annotation data modeling issues are not black and white. There are
frequently multiple ways to model an annotation.
•
Emblem scholars are sensitive to target granularity but less so to body
granularity (e.g., they have a strong desire to annotate something specific
but the annotation content frequently conflates multiple motivations and
types)
•
How will these nuances be leveraged?
