The traditional software development approach, together with the increased functionality required by incremental market segments, has led to monolithic applications that become more and more complex every day. The transformation to a component software industry is being fueled by the need to develop customized software solutions through the use of modular building blocks. Such a modular approach will reduce the overall complexity and code size of the software. It will also enable developers to use many code components again and again in different applications—and in some cases, to market their components to other developers. In all these ways, the component approach will help developers be more competitive. Software development based on components offers these business and technical benefits: • Reduced cost of developing and maintaining applications • Faster time to market • Ability to reuse code (a previously unfulfilled promise of software development) • Quicker response to customer needs, including the ability to easily customize software to satisfy different market segments • Higher-quality and more reliable systems that can grow with business needs • Development of less-complex, self-contained modules that are easier to test and debug, resulting in higher customer satisfaction • Easier software integration and creation of compound documents To respond to industry needs and enable the development of a true component software industry, Apple Computer, Inc. created the OpenDoc architecture in cooperation with IBM Corporation and Novell, Inc.—a partnership known as Component Integration Laboratories (CI Labs). OpenDoc is an industry standard for software integration that enables the development of cross-platform component software. Vendors who intend to offer products based on OpenDoc include Apple for Mac OS, IBM for OS/2 and AIX, and Novell for Windows. The Macintosh implementation will include the OpenDoc Standard Interchange Format (Bento), the Open Scripting Architecture (OSA), OpenDoc Compound Document Services, and OpenDoc Component Services from Apple; the System Object Model (SOM) technology from IBM; and the Component Glue technology (for interoperability between OLE and OpenDoc components) from Novell. This document provides an overview of Apple’s OpenDoc tools strategy. It describes the different tools that developers can use to develop OpenDoc components not only for the Macintosh platform, but also for cross-platform deployment. Tools for OpenDoc Development Page 1 First, however, we will take a brief look at the types of developers who can most benefit from OpenDoc. Tools for OpenDoc Development Page 2 Software Developer Segments There are many types of developers and there is no simple way to characterize each type’s use of and requirements for development tools. For the purposes of this paper, we will consider the needs of four major developer segments: • Application developers • Solution developers • Content developers • Client/server developers Application developers Application developers consist of traditional software developers: commercial developers, in-house developers, system integrators, VARs, and independent consultants. These developers typically use languages such as Pascal, C, and C++, and integrated development environments that offer compilers, debuggers, linkers, and a variety of low-level, high- performance tools. Application developers need to get the most out of a platform to keep pace with the ever more complex requirements of their customers. Today, they face technical and economic challenges that force them to: • Create larger, more feature-rich, and therefore more complex applications to meet increasingly ambitious and changeable customer requirements • Work with more complex and numerous system software APIs in order to incorporate the latest technologies in their applications • Create products that will run on multiple platforms with minimal additional investment • Develop this complex, cross-platform software quickly and easily Solution developers Solution developers deliver innovation and benefits to end users by integrating applications and components into seamless solutions. These developers must: • Rapidly prototype new solutions • Quickly and easily develop solutions that are inexpensive and yet can grow with their customers’ needs • Develop solutions without extensive programming so that they can focus on understanding business needs rather than computers • Quickly and easily customize a solution developed for one customer to another customer’s specific needs Tools for OpenDoc Development Page 3 Content developers Content developers create compelling interactive experiences for their customers by integrating media developed using specialized tools for sound, video, animations, graphics, and/or images. They need to: • Integrate content developed with different tools • Make multimedia content that is compelling and performs well without having to deal with complex programming languages (such as C or C++) • Ensure that even the most naive computer users (including kids) can take advantage of the content they develop • Deliver content that will play on any platform or configuration Client/server developers Client/server (C/S) developers build applications that must scale to the variable resources of an organization while tapping into the growing body of corporate information and systems. C/S developers must be able to: • Scale their applications for distributed environments • Integrate a growing body of legacy code into new solutions • Master code reuse and repurposing • Create interoperability between heterogeneous systems OpenDoc: A solution for diverse developer needs Developer needs are truly diverse, but all developers need to

    Digital Preservation Assessment: Date: 20/09/2016 Preservation Open Document Text (ODT) Format Team Preservation Assessment Version: 1.0 Open Document Text (ODT) Format Preservation Assessment Document History Date Version Author(s) Circulation 20/09/2016 1.0 Michael Day, Paul Wheatley External British Library Digital Preservation Team [email protected] This work is licensed under the Creative Commons Attribution 4.0 International License. Page 1 of 12 Digital Preservation Assessment: Date: 20/09/2016 Preservation Open Document Text (ODT) Format Team Preservation Assessment Version: 1.0 1. Introduction This document provides a high-level, non-collection specific assessment of the OpenDocument Text (ODT) file format with regard to preservation risks and the practicalities of preserving data in this format. The OpenDocument Format is based on the Extensible Markup Language (XML), so this assessment should be read in conjunction with the British Library’s generic format assessment of XML [1]. This assessment is one of a series of format reviews carried out by the British Library’s Digital Preservation Team. Some parts of this review have been based on format assessments undertaken by Paul Wheatley for Harvard University Library. An explanation of the criteria used in this assessment is provided in italics below each heading. [Text in italic font is taken (or adapted) from the Harvard University Library assessment] 1.1 Scope This document will primarily focus on the version of OpenDocument Text defined in OpenDocument Format (ODF) version 1.2, which was approved as ISO/IEC 26300-1:2015 by ISO/IEC JTC1/SC34 in June 2015 [2]. Note that this assessment considers format issues only, and does not explore other factors essential to a preservation planning exercise, such as collection specific characteristics, that should always be considered before implementing preservation actions.

AUTHORS DATE pp ref H. Kuiper and J.C. Donker 960725 36 8 DESCRIPTORS Computer graphics Multimedia Document storage Software tools Document markup languages Standards Format Texts Hypertext Word processing Information dissemination ABSTRACT Nowadays more and more information is being exchanged electronically. Reasons for this include a higher degree of cooperation between information suppliers and users, an increasing demand for speed (of production and modification, and reduction of time to market), and cost reduction. On the technology side, the advent of the electronic highway enables effective and efficient electronic information exchange. For reasons of timeliness and life cycle costs, standards and specifications are becoming more important. The aim of this paper is to provide an overview of standards and specifications for electronic exchange of (technical document) information and to discuss the most common ones currently available for text, images, and document exchange. Emerging standards and specifications, such as for audio, video and virtual environments are also briefly discussed. Finally, a brief description is given of a standard for enterprise integration and product data exchange.

  • Enabling White-Box Reuse in a Pure Composition Language
    Enabling White-Box Reuse in a Pure Composition Language Diplomarbeit der Philosophisch-naturwissenschaftlichen Fakultat¨ der Universitat¨ Bern vorgelegt von Andreas Schlapbach Dezember 2002 Leiter der Arbeit: Prof. Dr. O. Nierstrasz Nathanael Scharli¨ Institut fur¨ Informatik und angewandte Mathematik i Abstract Inheritance is a key concept of object-oriented programming languages, features such as conceptual modeling and reusability are largely accredited to it. While many useful com- ponents have been, and will be, developed in this paradigm, the form of white-box reuse offered by inheritance has a fundamental flaw: reusing components by inheritance requires an understanding of the internals of the components. We can not treat components of object-oriented languages as black-box entities, inheritance breaks encapsulation and in- troduces subtle dependencies between base and extending classes. Component-oriented programming addresses this problem by shifting away from program- ming towards software composition. We build applications by scripting components. In- stead of overriding the internals of a component, we focus on composing its interfaces only. This form of black-box reuse leads to a flexible and extendible architecture with reusable components. In this master's thesis we propose a migration strategy from class inheritance { a white- box form of reuse { to component composition as a black-box form of reuse. We present a language extension that gives us the power of inheritance combined with the ease of scripting. It enables us to reuse Java components using inheritance in JPiccola { a small, pure and general composition language implemented on the Java platform { at a high level of abstraction. Using the services provided by the language extension we can seamlessly generate interfaces and subclasses from JPiccola.

  • Smalltalk Volume 2 Issue 7
    The International Newsletter for Smalltalk Programmers May 1993 Volume 2 Number 7 ecognizing Smalltalk’s increasing importance as a mainstream pro- TOWARD A gramming language and acting as a large user of the language, IBM D recently proposed the formation of a standards effort within ANSI to define a Smalltalk language standard and offered a “common SMALLTALK base” strawman to start such an effort. At this time the proposal has beenQaccepted by the ANSI SPARC committee, and the formation of an ANSI STANDARD: Smalltalk committee has begun. This article focuses on technical issues regarding the common base. We have written a companion article that will appear in OBJECT MAGAZINE,which outlines TECHNICAL ASPECTS the history of the development of the common base. WHAT IS THE COMMON BASE? OF THE COMMON BASE As part of the proposal for an ANSI Smalltalk standards effort, we have con- tributed a “strawman” as the starting point for standardization. That strawman is contained in the IBM document entitled Smalhalk Portability A Common Base By R.J. DeNatale and comprises chapters 3–5 and appendices A and B from that document. * & Y.P.

The opportunity has therefore come to look back and give due credit to those who have supported and encouraged me in different ways. My first interest in the object-oriented world began in 1989 when my former manager at Tietotehdas Oy (Tietoenator nowadays) Vice President Tiina Kurki asked me if I wanted to get to know what objects actually are.
