Part 2
The 5S Model:
A Formal Model for the
Digital Library
Motivation
• DLs are not benefiting from formal theories
as have other CS fields: DB, IR, PL, etc.
• DL construction: difficult, ad-hoc, lacking
support for tailoring/customization
• Conceptual modeling, requirements analysis,
and methodological approaches are rarely
supported in DL development.
• Lack of specific DL models, formalisms,
languages

•
help satisfy info needs of users (societies)
provide info services (scenarios)

Document Models,
Representations, and Accesses
• Doc = stream + structure + use-scenario; hybrid
(paper/electronic), digital only
• Multilingual: content, summary, metadata
• Multimedia: structure, quality (oS), search
• Structured: MARC, SGML, by user: MVD
• Distributed collection: Kleisli, CIMI, Z39.50
• Federated search: collecting, picking site(s),
parallel search / fall-back, fusing results
• Access: IPR, payment, security, scenarios
Architectural Issues
• Internet middleware
• Independent system / part of federation
• Decompositions vary
• search engine, browser, DBMS, MM support
• repository, handle server, client
• information resources + mediators, bus or agent
collection + client with workspace/environment
• Metrics: e.g., for federated search
Standards
• Protocols/federation
• Z39.50, CIMI
• Dienst, NCSTRL
• OAI protocol
• Metadata
• TEI: inline, detailed (structure in stream)

Challenges with Approach
• The designer should know the 5S theory
very well and be very familiar with the
syntax and semantics of 5SL to be able to
write correct 5SL files.
• It is difficult to get the big picture of a
digital library just from a textual 5SL file.
5SGraph: A DL Modeling Tool
(Qinwei Zhu MS Thesis)
•
Overall objective of 5SGraph:
Help users model their own instances of a digital
library (DL) in the 5S language (5SL).
A simple modeling process which enables rapid
generation of digital libraries is needed.
•
•
•
•
Support non-expert users.
Speed-up development process.
Increase the quality of final product.
Goals of 5SGraph
• To help digital library designers understand the
5S model quickly and easily
• To help digital library designers build their own
digital libraries without difficulty
• To help digital library designers transform their
models into 5SL files automatically
• To help digital library designers understand,
maintain, and upgrade existing digital library
models conveniently
5SGraph
How does 5SGraph work?
• 5SGraph loads and displays a metamodel in a
structured toolbox.
• The structured editor of 5SGraph provides a topdown visual environment for the DL designer.
• 5SGraph produces correct 5SL files according to
the visual model built by the designer.

toolbox
(metamodel)
Overview of 5SGraph(cont.)
• Structured toolbox
• Show the available concepts in metamodel and
the relationships between those concepts.
• Visualize the Metamodel
• Concepts in structured toolbox can be added
into workspace.
• Workspace
• Visualize the model
• The place where the user creates his/her model.
Visualization Features
• The structured toolbox
• Visualization of the metamodel
• Visual components that can be added
• Truncated display of trees
• Node-link representation
• Deep-node problem
• Icons
• Type/Instance relationship
• Cardinality
Component Reuse
• Components can be loaded/saved.
• Load and save sub-trees
• Component reuse saves time and effort.
• Full reuse from component pool
• Partial reuse: adapting components

Add a concept to user model
• Top-down: Before you want to add a concept,
make sure you have added its parent.
• You can only add a concept to its parent node
• Make sure the parent node is chosen before you
add a new concept.
• If the highlight color is blue, the concept has satisfied
all the requirements and can be added.
• If the highlight color is yellow, click the parent node in
workspace and then add the concept.
Add a concept to user

• Double-click the concept in toolbox
or
• Right-click and choose the item in the popup menu
Add a concept to user

Delete a concept
• If the concept has no child concepts, click
the concept first, then press “Delete” key.
• If the concept has child concepts, delete the
child concept first, and then delete this
concept.
Change the name and properties of
concepts
Change the name and properties of

Load/Save concepts
Semantic Constraints
• There are inherent semantic constraints in the
hierarchical structure of the 5S model.
• 5SGraph maintains the constraints and
enforces these constraints over the instance
model to ensure correctness.
Example 1 (Constraint Enforcement)
• An actor can only participate in the
services that have been defined in the
Scenario Model.
Example 2 (Constraint Enforcement)
• A catalog has descriptive metadata for
digital objects in a specific collection.
• Therefore, a catalog must have a 1:1
relationship with an existing collection.
• Thus, a catalog is not independent.
The Preliminary Test of 5SGraph
• Research Questions
• Does the tool help users understand and use
the 5S model to build their own digital
libraries?
• Does the tool help users efficiently describe
digital library models in the 5SL language?
• Are users satisfied with the tool?
The Preliminary Test of 5SGraph:
Experimental Design
•
Three tasks
1. Build a simple digital library using existing
components.
2. Complete the partial model for CITIDEL.
3. Build a model for NDLTD from scratch.

Semantic Modeling of Digital
Library with Concept Maps
• Customized “plugin” tool to model
scenarios and societies
• Tools with common principles,
abstractions, graphical notations, and
operations
• Solution: Concepts Maps
• Conceptual tools for organizing knowledge
and representation
Conclusions
• Presented a domain specific visual
modeling tool for DLs.
• Evaluated the tool and proved efficiency,
effectiveness, and learnability.
• Built new tools based on concept maps for
scenario and societies modeling.
Future work on 5SGraph
• Integration of tools
• Further usability studies with “digital
librarians”
• Usiing the tools as educational aids for
teaching about digital libraries
Motivating Problems – Toward 5SLGen
(MS Thesis of Rohit Kelapure)
•
Lack of general models for Digital Libraries (DLs)
•
Little focus on simplifying the process of modeling and
building DLs
•
Divergent DL architectures
•
•
Monolithic: Tightly integrated and generally inflexible
Componentized: A network of interoperable components
aggregated without a design methodology
Problems (contd.)
• Lack of DL-specific modeling languages,
software toolkits, prototyping and CASE tools
• Lack of a scenario-based requirements analysis
and design approach to DLs
• Implication: Problems with
• Interoperability
• Customizability
Approach
•
Based on the formal 5S theory
• Streams, Structures, Spaces, Scenarios and Societies
•
Use of
• Domain-specific declarative languages (5SL)
• Scenario-based requirements analysis and design
• Componentized architectures
•
Automatic transformations/mappings from models to code
•
Special attention paid to issues of flexibility, reusability,
and extensibility
Approach: 5SLGen
• 5SLGen is a new generic digital library generator.
• It has been developed, implemented, and
deployed in several applications.
• 5SLGen yields implementations of digital library
services from models of DL “societies” and
“scenarios”
(and from the other “Ss”).

componentized DLs
•
