• There is a huge difference between providing access to sets of digital collections and providing digital library services
• The first significant federal investment in digital library research came in 1994 with the Digital Libraries Initiative- this was mean to develop and implement computing and networking technologies that could make large-scale electronic test collections accessible and interoperable.
• These initial initiatives served to identify and define important document and data metadata standards, protocols for Web-based access, and the issues surrounding federated and broadcast search protocols.
• These projects are also known for their examination of issues surrounding federation
• XML is based on SGML
• XML catalogs defines a format for instructions on how an xml processor resolves XML entity identifiers into actual documents
• Namespace provides a mechanism for universal naming of elements and attributes in XML documents
• There is a competition of sorts between the W3C XML schema and other XML markup languages such as RELAX NG
