| We describe the relevance of Advanced Web Technologies for Industry and Education |
| WebWindows is the basic Web Operating Environment for which one will build software products |
| We use WebFoil as an example to illustrate the WebWindows approach to WebTop Productivity software with open modular design |
| Java, PERL, VRML, Telescript, Video/web servers are critical advanced technologies but there also opportunities to take existing technologies such as relational databases and integrate with Web |
| Major initial opportunities include use of Web in Business Enterprise Systems |
| We also can develop new approaches to delivery of education at all levels such as in Living Schoolbook |

| Rather one will write software for WebWindows defined as the operating environment for World Wide Web |
WebWindows builds on top of Web Servers and Web Client open interfaces as in

Applications written for WebWindows will be portable to all computers running Web Servers or Clients

| 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 |

| 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 |

| 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 ontop of WebWindows-- the correct implementation of HPCC ideas such as HPF,MPI with pervasive technologies and good software engineering |
| WebScript -- The evolving Middleware of scripted languages including PERL5, Java, Telescript, MOVIE (NPAC early prototype), domain specific Problem Solving Environments |
| This will lead upto Ultimate Goal! Televirtuality -- All Web Users are linked into a single virtual world |

| 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 |
| Telescript -- forced into semiopen by Java (!?) -- dynamic Web Transport and Server technology replacing HTTP,MIME .. |
| Multithreaded WebServers integrating current Web, Compute and digital multimedia delivery services -- future Enterprise Systems |

| Persuasion and Powerpoint are rather similar monolithic packages which can for instance only be clumsily ported to UNIX as cannot access internal data-structures defining foils |
| WebFoil (NPAC prototype WebWindows presentation package) has |
Extended open HTML source manipulated by powerful PERL5 scripts allowing global changes and linkages of foils from many sources
|
| WebFoil Uses Hotjava to display HTML with full Web Power including applets to enable Multimedia and dynamic presentations |

The WebTop Productivity environment will be built in a more modular fashion than current PC Windows or Macintosh arena
|
| Java is key to understanding how WebWindows application/service software will look as it allows balanced client server applications to be built |
| Note require an open display software so can produce appropriate customized interfaces for browsing, presenting, word processing etc. |
| Java may or may not be accepted by Web Community and Sun/Netscape may or may not allow it to used openly |
| However the concept is essential and roughly right -- one or more such open technologies will become available and used on the Web |

| InfoVision is "successor" to TV with any multimedia information delivered on demand( choice from infinite number of channels) |
| Community Networks will define local societies and will have significant impact on local government |
| Shopping on the Web will include multimedia digital yellow pages , Commerce, online catalogs (which is InfoVision again) as well as perhaps powerful VR interfaces where you can try out new clothes and cars |
| Collaboration (gossip as in computer forums) could be an important and dominant use but perhaps not initial major one |

OLTP (Online Transaction Processing) such as approving and recording credit card transactions. This is a type of InfoVision and Commerce which is operational today
|
| Decision Support varies from fraud detection, inventory planning and market segmentation for optimizing shopping by mail |
| Decision support can vary from search of a single giant relational database to galaxy-wide search of heterogeneous distributed database |
| Workflow Support as in LOTUS Notes integrates Collaboration, Project Management and Distributed Databases. This supports ongoing distributed enterprise -- this is also essential in collaboratory |

| This (as developed) enables a wonderful new software industry as Microsoft no longer has key advantages |
This (as used) enables very effective (business) enterprise systems where "Web" used internally to an enterprise

| Collaboration between commander in field , specialized anchor desks (domain experts) and those in field. |
| User Interface essential as user will be tired and searching unfamiliar data |
| Geographical Information Systems and browsing multiple video sources (InfoVision again) will be critical as judgements will depend critically on spatial data. |

| This is future model for (inter)national distributed research |
| Rich Collaboration environment essential as collaborative research requires nontrivial person to person interactions |
| Searching distributed databases basis of much scholarly work (infoVision and Digital Library) |
| Metacomputing for multidisciplinary, multi-institutional simulations and for control and data storage and analysis from remote instruments whether satellites, telescopes, accelerators etc. |
| Distributed (people) Software Engineering support for production of distributed computing software |

| VRML illustrates how one can store real world objects in a universal fashion |
| Game vendors can build modules that interact and enable development of amazing profitable virtual worlds! |
| Manufacturers can use VRML as basis of universal product definitions enabling collaborations between several vendors needed for Multidisciplinary analysis and design cf: PDES/STEP standards |
The Web "levels" the playing field for all software products

Three types of modules are supported:
|
| Developer modules are linked to the agent module and report automatically all changes in the software volume (handled by WebTools CASE toolkit integrated with WebTools editor). |
| The agent module integrates the results and uses customizable threshold to decide when to fire a report to the manager or a deadline reminder to a developer. |
