4. What is Superimposed Information?
Give a definition
Base layer/superimposed layer

Stream Semantics

5. Superimposed Information has Existed for Millennia
Religious and legal commentaries
Example of bible commentary
Concordance
Example of Shakespeare concordance, maybe one with excerpts showing context

6. Notice the Addressing Notice the addressing systems
Book, Chapter, Verse
Play, Act, Scene, Line

7. Can Also Go Inline Interlinear exegesis
Example of Luther’s bible, linguistic markup

8. New Possibilities with the Advent of Digital Information
Much easier to access information (?)
Do I need this slide?

9. Examples of Superimposed Information and Applications
Bookmarks, Favorites in browser
Screen shot?

10. More Examples Classification: Thingifier Screen shots?
What about OGI Website?
What about strand maps
What about XLink?
Acrobat notes
Superimposed Schematics browser

11. SidePad Explanation, (Scenario?) Back-up pictures Demo:
Create items in 2-3 different apps, label, reactivate, group, link??
Open existing SidePad, activate items, browse contect
Query to produce outline view?

12. SI Modeling Different superimposed information models
Collections: Thingifier
DAG: Strand Maps
ER: Schematics Browser
What is it for InVivo?
What is it for Acrobat notes? location-comment pairs?
SidePad: Show information model

13. Granularity of Addressing
Bookmark list: whole web pages (maybe anchor sites)
SidePad: application-selectable regions
XLink: XPath spans

14. Stand-off vs. In-line Modify base layer versus reference it
Issues with Stand-off
Changes in base layer
Traversing from base to superimposed layer
Issues with In-line
May not own base layer
Alternative SI on same base document
How do you have SI span documents?

15. Encapsulated vs. Embedded Marks
CARTE had mark info directly in superimposed information
Hard to share marks across different SI models
11 November 2018
Stream Semantics

16. Our Approach Subdocument granularity Stand-off SI
Support multiple SI models
Encapsulated Marks

17. SPARCE Architecture Slides from New Zealand? 11 November 2018

18. Different Approaches to Marks
Encapsulated vs. Explicit
Use of repository or not, affect on collections
Homogeneity vs. Heterogeneity
Of base type
Of machine environment
API to mark, excerpts, context
Where interpretation is done
Local context manager
Remote server sends modified content
Remote server sends local script

19. Semantic Marks Slide or two from Susan 11 November 2018
Stream Semantics

20. Converting an Existing Model to Superimposed Use
Want to take some existing model, and associate marks with its constructs
Show some alternatives for XML
Extra sub-elements (hard for attributes)
Parallel structure
Associating mark with a span of text

Stream Semantics

21. Extending ER-style Models
Sun’s work on Relationship Patterns
Introduce scenario of system bug and update browser
Show info model, talk about different things to associate base info with (entity, attribute, relationship)
Short intro to relationship patterns
Show use of patterns for mark inclusion

22. Dealing with Multiple Models
Superimposed structure (or goes with semantic marks)
Bi-Level querying (WebDB slides?)
Examples from system update and bug browser
Use of queries to span SI and BI
Use of queries to switch SI models: Convert to timeline

Joint work with Virginia Tech, Villanova
What do instructors, students, authors do with material found in a digital library?
annotate
excerpt
combine
link
re-organize
