By definition, Web Software will be the "best" software ever built because it has the largest market (and so greatest leverage of investment dollars) and most creative business model (harness the world's best minds together with open interfaces)
|
One should build upwards from the "democractic Web"
|
| This allows you to both deliver your application to the general public (not always required but often desireable) and use the best leveraged software |
| Note Web Software tends to offer highest functionality as opposed to highest performance and HPCC often requires different trade-offs |

Web Technology is still uncertain and there may be major changes but "enough" capabilities are in place to build very general (~all) applications

| Fortran 77 -> Fortran90 --> HPF --> Fortran2000 (23 years) |
VRML Idea (1994) --> VRML1 deployed (95) --> VRML2 deployed (early 97) (2.3 years)

In future one will NOT write software for either
|
| 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 which hide hardware and native O/S specifics |

Further WebWindows Software will be modular and allow plug and play insertion of capabilities developed around the Web World -- not a bunch of isolated stovepipe solutions
|
| As an example some of Current Netscape and last year(!) NPAC's WebTools implements UNIX shell/PC file manager capabilities in terms CGI scripts -- allows universal access to these capabilities including powerful Web based (mh) mail |
| NPAC's WebFoil is HotJava/Netscape 1,2,3 Open replacement for Powerpoint/Persuasion |
Particular Application areas (Business, Healthcare, Education) will be built on top of generic NII services so that for instance

| 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
|
| Backend Oracle database illustrating modular WebWindows approach |
| Using Appropriate templates WebFoil Uses Hotjava or Netscape 1,2 or 3 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 or equivalent future technology 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. |

| Most of the real world WebTop Systems will involve multi-user collaboratory modules. Even for scientific computing, complex toolkits such as WebAMR will be most conveniently supported by interactive consultation between developers and users. |
| Collaboratory multi-user components will be further enhanced in enterprise, commerce and community systems. |
| This is illustrated in our recent telemedicine prototype for nursing triage. Here we start from the collaboratory component involving nurses, nurse practioners and pediatricians and add HPCC components such as medical imaging and agent based diagnosis. |
| We view the Bridge topology (Warner & Balch '95), underlying such telemedicine systems, as a promising generic framework, applicable also for other problem domains. |
A generic bridge includes "points of need", "points of expertise" and intelligent middleware that manages information resources and provides connectivity between customers and optimal services.

Take Web electronic society technology which link people together and use to join teachers mentors and students
|
| Meanwhile can look at VRML2 for Immersive virtual learning environments |
| All of these technologies can be used either synchronously (organized sessions) or asynchronously (students learn in their own time and interact with teacher/mentor in batch mode) |
| Log educational sessions (including multimedia material) in databases and use for assesment |

Initial applications include corporate training and University continuing education
|
| This is outreach to people wanting to learn new skills and so critical as all organizations redefine themselves |
| Also use in Chinese Universities and HBCU's in the U.S. where we can help faculty upgrade their curricula |
| NPAC will have all these capabilities in a deployable system by end of 97. |

| 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 |

| Critical feature is realtime, "come as you are" adaptive linked computers and people |
| Judgement support extends decision support into an "exploratorium" scenario as crises tend to be unexpected |
| Major need to search community and government databases for immediate information on resource location and availability etc. Metadata(summaries) essential |
| 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. |
