UKOLN supports the JISC IE (Joint Information Systems Committee Information Environment). The document discusses the JISC IE architecture and how it presents a view of networked services. It describes some of the technologies used in the JISC IE like cross-searching, harvesting, link resolution, and metadata standards. The document also discusses the relationship between shared infrastructural services, common services, and the JISC IE and E-Learning Framework. It argues that some services are best delivered as shared infrastructural services while other functionality may be common across different components.
