Document Representation

• Articles Encoded in XML (Various Schemas)
• Vendor-Neutral, Platform-Independent Standard
• Fine-Grained Markup of Intellectual Structure
• Transformable Extensible (Metalanguage)
• More Web Application Friendly than SGML
• Articles Broken into Components for Storage
• As-Published Text (static)
• As-Published Figures Tables (static)
• Metadata (dynamic)
• links parts, references, related, alternate,
  value-added

Architecture Approach

• Distributed, Modular Repositories
• Distributed Document Storage (e.g., by Publisher)
• Separates Document, Metadata, Index, Gateway
• Assumes Distributed, Standards-Based Clients
• Implementation Issues
• Multiple Views Resource Combinations
• Cross-Repository Searching Harvesting Vs. Agents
• Pre Post-Coordinated Transformations

Search Retrieval

• Depth vs. Breadth
• Exploit Unique Markup Schema to Search
  Homogeneous Collection with Fine-Granularity
• Transform Metadata to Common Semantics to Search
  Across Heterogeneous Repositories
• Search Enhancements
• Normalization Value-Added Content
• Noun Phrase Co-Occurrence
• Searching for Mathematics, etc.

Presentation to End-User

• Delivery Format Options
• XML with XSLT or CSS, helper plug-in / behavior
• XML with XSLT or CSS, view natively in browser
• XHTML with CSS, view natively in browser
• Ancillary Issues
• Authentication, Permissions Authorization
• Desired View (e.g., metadata, document, merged)
• Server-Side vs. Client-Side Transformations
• Link Resolution Issues (Appropriate Copy)
