  2. 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 ASIS Annual Meeting 2000

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 ASIS Annual Meeting 2000
