Overview
We now have the tools to pursue the grand challenges of Information Retrieval:
Standard retrieval environment (Web) and interface/client (Browser).
Ability to perform standardized searching (HTTP Post/Get, SQL, Z39.50).
Standard language for describing and transforming content and metadata (XML, XSLT, DC, RDF, Schemas).
Standard transport mechanisms to connect heterogeneous content (HTTP, B2B, SOAP).
