Full HTML Index
| Clients (such as Mosaic and Netscape) support browsing of hyperlinked documents but have no internal interactive/compute capability |
| Servers read HTTP and deliver requested service to client |
| HTML -- a document format supporting hyperlinks |
| HTTP -- a Transport Protocol defining Interaction between Web servers and Clients |
Full HTML Index
| MIME -- a data format allowing agent-like (extended email) communication |
| CGI -- a standard interface allowing sophisticated server extensions |
| PERL -- a rapid prototyping language(script) aimed at text and file manipulation |
| Web Search engines such as YAHOO, HARVEST, WAIS -- early distributed database access technology supporting search and indexing |
| net.Thread, WebTools, RealAudio are early Web Interactive services |
Full HTML Index
| Relational databases -- Oracle,DB2 have Web Interfaces |
| Collaboration from Console Units (PIctureTel, CLI), Desktop (SGI Inperson) to MOOs |
| Compression from MPEG and Wavelet to host of proprietary solutions -- a faction of 20 to 200 saving in space and bandwidth |
| Geographical Information Systems |
| Security will enable commerce on the Internet -- essential for Defence as well |
Full HTML Index
| ATM, ISDN, Wireless, Satellite will be hybrid physical implementation of NII |
| CORBA, Opendoc, OLE, SGML, Hytime are critical file and document standards |
| High Performance Multimedia servers to enable digital information delivery on demand |
| Data transport from MPI/MSGWAY/PVM to AAL to CBR/VBR |
| Windows95/NT -- the last of the the non social(Web) operating systems -- will follow dinosaurs(IBM mainframes) into extinction |
| Personal Digital Assistants -- WebNewtons done right -- Telescript (agent based communication) and Magic Cap operating system |
Full HTML Index
| WebWindows -- the open nonproprietary operating system of future supplanting UNIX, Windows95/NT, Apple etc. -- manages with a single interface all machines either individually or collectively on the NII |
| WebWork -- Implements Computing for both Simulation and Information underneath WebWindows -- the correct implementation of HPCC ideas such as HPF,MPI with pervasive technologies |
| Personal Servers -- Newton was correct but too early. The Web is a server - server technology |
| Televirtuality -- All Web Users are linked into a single virtual world |
Full HTML Index
| Java -- an interpreted C++ like language (script) allowing fully interactive clients which execute applets. Has full set of classes to make clients such as HOTJava. Licensed by Netscape |
| VRML -- a 3 dimensional HTML allowing universal description of physical objects and allowing interchange of virtual worlds, commercial product designs etc. |
| PERL5 -- an extension of PERL4 with full object oriented characteristics and extended pointer(array) constructs -- allows construction of Web Software obeying good software engineering practices |
| Multithreaded WebServers integrating current Web, Compute and digital multimedia delivery services -- future Enterprise Systems |
Full HTML Index
| WebTools -- Early NPAC Prototype of WebWindows Equivalent to Program Manager with Navigation, File manipulation, Mail |
| WebDeskTop Publishing -- an early killer application under WebWindows supplanting Word, Wordperfect, LOTUS123 , Persuasion etc. Java allows clear powerful implementation. |
| WebRDBMS -- Integration of Relational and Distributed databases with both agent based heuristics, formal indices and free text search |
| Metadata -- Common attributes to allow integration and search of heterogeneous databases |
Full HTML Index
| WebSpace -- Televirtual implementation of full 3D MOO like environment building on LabSpace at Argonne for the virtual scientific laboratory |
| WebFlow -- NPAC prototype of Web based extended Khoros/AVS supporting dataflow linkage of computers for simulation and people and data for workflow management |
| WebScript -- the evolving Middleware of scripted languages including extended PERL5, Java, Telescript, MOVIE(NPAC compute oriented script) etc. |

| Like UNIX or MS-DOS or Windows 3.1(NT,95), WebWindows is an operating system for a "computer" |
| The "computer" is a metacomputer consisting of the 50,000 Webservers (currently--eventually hundreds of millions) on Internet for the World Wide Web |
WebWindows can also be used for the metacomputer (collection of heterogeneous networked computers) which is a business enterprise system
|
WebWindows is a multi-client multi-server technology
|
Full HTML Index
| Includes World wide multimedia File access and dissemination -- current immediate Browser Services |
| Initial Websearch and agent technology such as World Wide Web Worm, Lycos,Yahoo, Harvest etc. |
WebTools is initial NPAC Project to illustrate future WebWindows
|
| WebWindows development team will run using a network of WebTools servers -- each user will run personal server |

| It does not provide multi-threading/multiu-user support, memory management, device drivers and such base services -- these are supplied by UNIX, Windows or Mac O/S |
| Rather it provides equivalent of higher level O/S services such as available under UNIX shell or applications supplied under Windows |
| In the future one will build applications for WebWindows not UNIX / PC windows etc. |
Very interesting is WebWindows version of Lotus Notes to support Business Enterprise systems -- build from Web components such as those prototyped in WebTools
