Four sample NCSA Mosaic (described on 

 page 44 in the ASTA section) screens show- 

 ing access to images contained in public 

 Internet digital data libraries. From top to 

 bottom: 



• The Mosaic Demo document directly accesses 

 a gopher server at the University of Illinois' 

 Weather Machine containing current weather 

 data (here the Flood of '93) 



• The Dinosaur fossil exhibit developed by 

 Honolulu Community College- The exhibit uses 

 audio clips, images, and text to educate and 

 entertain. Users can take a narrated tour by 

 selecting the audio links throughout the docu- 

 ments 



• Two images from "Rome Reborn: The Vatican 



Library and Renaissance Culture. " an exhibit 

 at the Library of Congress: 



- One screen from this hypertext exhibit. 



■ Botanical pages from Materia Medica. a 14th 

 or 15th century Italian manuscript. 



IITA 



IITA component activities are designed to expedite the 

 application of research products and services developed 

 in the original four component areas to National 

 Challenges. Efforts in IITA will build on and integrate 

 fundamental HPCC technologies in order to enable 

 widespread progress on information-intensive applica- 

 tions in such areas as the civil infrastructure, digital 

 libraries, education and lifelong learning, the environ- 

 ment, health care, and manufacturing. NSF will focus 

 primarily on building and promulgating intelligent user 

 interfaces, distributed software systems and support 

 environments, standardized data management and 

 communications processes, and enhanced information 

 infrastructure services. IITA activities include: 



-"Support for development of tools and mechanisms 

 for enhancing human communication and collabo- 

 ration across the network. 



-" Development of multimedia software and educa- 

 tional materials. 



-"Support for basic and strategic research on devel- 

 opment of advanced data capture, storage, repre- 

 sentation, and retrieval technologies for "digital 

 libraries." 



-"Training support for users in the generation and 

 use of digital library resources, fostering "lifelong 

 learning" opportunities and development of new 

 network-based training modalities. 



-"Pilot projects for information-intensive applica- 

 tions. 



BRHR 



BRHR component activities are designed to encourage 

 research projects and infrastructure and educational 

 activities that ensure the flow of innovative ideas and tal- 

 ented people into high performance computing technolo- 

 gies and application areas. Activities include support for 

 research in fundamental areas of algorithms, data struc- 

 tures, programming languages, operating systems, soft- 

 ware engineering, performance evaluation, databases, 

 digital libraries, information science, knowledge process- 

 ing, language and speech understanding, computer
