[edit] Deletion

The article was proposed for deletion due to notabilty. The text below (which I didn't see before) mentions several written sources referencing Newi, as does Erik Persson's doctoral thesis Shadows of Cavernous Shades: Charting the Chiaroscuro of Realistic Computing. I will remove the deletion template now. Nixdorf 21:30, 30 July 2007 (UTC)

I think perhaps this ort to either go on to the page with references or go completely and be put on to a page under it's real name. This company is not the only one using the abbreviation NEWI so it seems only fair that the companies are listed here and the info moves to a page under the company name. No objections and I will move it Delighted eyes 04:32, 31 July 2007 (UTC)

[edit] (older message)

The initial concept behind Newi originated in 1989 when Oliver Sims, then working for IBM, saw the need for an infrastructure whereby a given real-world business concept (process or entity) could be implemented as a software module that could be plugged into a running system. Applications would be created by composing an appropriate set of modules. IBM UK funded development of the concept through collaboration with Softwright, a UK bespoke software company.

After several successful prototypes, and an early AS400 production version, a joint venture called Integrated Object Systems (IOS) was created in 1993 to exploit the concept. The first version of Newi was announced and shipped in 1994.

Newi was what today is called a component container. The concepts behind the Newi middleware can be found in Oliver Sims' book "Business Objects", McGraw-Hill 1994. In spite of the title, the book was about software components.

Newi components were language-neutral. That is, a Newi component could be written in one of a variety of languages that was supported by Newi. At its height, Newi supported software components written in Cobol, Ada, C, C++, Rexx, and Java. Platforms supported included Windows 3.1, Win95, WinNT, three varieties of Unix - and a prototype supporting components written in RPG was running on the AS400.

Newi components were intended to be "objects in the large". There was a form of sub/supertyping which was implemented by the infrastructure through an intelligent delegation mechanism. For example, a component written in C could be "subtyped" by a component written in Cobol. Component names (or types?) were separated from the code implementation module. Messages (both sync and async) were passed using a proprietary form of "tagged data" (a similar concept to today's XML). There was also a notification service. The various system services (including the GUI framework and comunications subsystems) were implemented as Newi components. Throughout, there was a rigorous focus on making the programming of application components as simple as possible, with Newi providing many transparencies.

From the start, Newi was targeted at both front-end GUI systems and back-end server systems. The front-end version had a GUI run-time framework implemented as components. The component concept fitted very well with the object-based UI provided. Hence a designer/programmer used the same technical code structure to implement both front-end and back-end business function.

In early 1996, IOS was bought by SSA (System Software Associates, Inc), who saw great potential in Newi. The software was significantly further developed within SSA, in particular in its back-end capability, as well as havinf its underlying communications function moved to a COTS Corba product that provided the communications "wet string" while maintianing the Newi programming model and loosely-coupled component interaction. Tools were also significantly expanded. SSA also announced an early and proprietary form of web services, based on the re-developed Newi, called "Semantic Message Gateways", or SMG.

In 1998, for reasons other than their technology base, SSA had to down-size dramatically, Newi development was halted then abandoned, and the development team (around forty people in UK and USA) was dispersed. Sic transit gloria mundi.

Two further books based on the Newi phenomenon are: Peter Eeles and Oliver Sims, "Building Business Objects", Wiley 1998. Peter Herzum and Oliver Sims, "Business Component Factory", Wiley 2000.
