TL;DR: The structure and content of STEP 55 is intended to provide a definitive statement of the STEP architecture and methods, to enable the application of the methodology, and to serve as a basis for training.
Abstract: test suites (Parts 301...) Conformance testing (Parts 31-39) Application protocols (Parts 201...) Application interpreted constructs (Parts 501...) Integrated resources Description methods (Parts 11-19) Implementation forms (Parts 21-29) Generic resources (Parts 41...) Application resources (Parts 101...) Figure 12: the STEP document structure Description methods The scope of the description methods class is that of the languages and methods used to create standard representations of product data. The description methods have been allocated part numbers between 11 and 19. To date, three parts have been identified within the description methods class: • Part 11: “The EXPRESS language reference manual”; • Part 12: “The EXPRESS-I language reference manual”; • Part 13: “Architecture and methodology reference manual”. Part 11 is included within the initial release of STEP. The structure and content of STEP 55 One of the key objectives of STEP is to provide unambiguous, computerinterpretable representation of product data. This is supported through the use of the EXPRESS language. EXPRESS is a data specification language that is used to represent the structure of data and any constraints that may apply to it. The data models contained in the STEP Integrated Resources and Application Protocols are defined using EXPRESS. Although EXPRESS resembles some programming languages, it cannot be used to define executable programs; rather, it is used to define the data on which programs operate. EXPRESS supports: • the definition of data entities, attributes, and relationships; • the specification of local and global constraints on these; • the collection of data definitions and constraints in separate schemas, supporting modular development of data models. Although EXPRESS has been developed as part of STEP, it is now widely used in other standardization, research, and integration projects. Further information about the EXPRESS language is given in Appendix B; Chapter 10 includes a summary of some of the software tools that are available to work with EXPRESS. The second STEP part in the description methods class is EXPRESS-I. This is a standard data instance definition language, ie. it may be used to specify actual values within an EXPRESS schema. EXPRESS-I is particularly useful in the specification of test data. Part 13 of the standard describes the detailed structure of STEP and the methods used to develop its various elements. It is intended to provide a definitive statement of the STEP architecture and methods, to enable the application of the methodology, and to serve as a basis for training. A summary of the STEP architecture and methodology is given in Appendix A of this book. Implementation forms One of the key differences between STEP and previous standards in the areas of CAD/CAM data exchange or data management is the separation of data definition from implementation. Thus within STEP the data models defined in the standard are designed to be independent from the various ways in which they may be implemented. The implementation forms class of parts defines standard 56 STEP for data management, exchange and sharing formats for data instances and values, and the mappings between these formats and the EXPRESS language. The implementation forms have been allocated part numbers between 21 and 29. To date, five parts have been identified within the implementation forms class. The most important of these are: • Part 21: “Clear text encoding of the exchange structure” defines the standard format for encoding of data in a file, and supports the exchange of data between applications. • Part 22: “Standard data access interface” enables access to product data within an application (an “engineering” application or a database management system) independently of the internal form of data storage within the application. Part 21 (commonly referred to as the “physical file” format) is part of the initial release of STEP. As well as Part 22 (commonly referred to as the “SDAI”), several additional parts within the implementation forms class define the bindings between the SDAI and specific programming languages including C, C++ and FORTRAN. An implementation form is not sufficient to define the complete requirements for a conforming implementation of STEP; in addition, a data model is required that defines the structure and semantics of the data to be handled by the implementation. Within the architecture of STEP, these data models are provided within Application Protocols, as described below. An implementation of STEP combines an Application Protocol with an Implementation Form; thus, the same data model is used (for example) for exchange of engineering drawings using files (on disc or tape) or for standard access to drawings within a database. Chapter 6 provides additional information on implementation forms, and their place within the implementation architecture of STEP. Integrated resources In Chapter 3, the idea of a conceptual data model was introduced. Within STEP, a single conceptual data model has been developed that reflects and supports the common requirements of many different product data application areas. This conceptual data model is modular in nature, and is published within the Integrated Resources class of parts. Even though the Integrated Resources are documented as a number of separate parts, the data model that they contain logically constitutes a single, integrated conceptual product data model. The structure and content of STEP 57 For the purposes of publication, Integrated Resources are divided into two separate series of parts: • the integrated generic resources (Parts 41...99) define the components of the conceptual product data model that are independent of applications; for example, Part 42 “Geometric and topological representation” defines the standard representations for the shapes of objects, independent of any specific use of the shape information; • the integrated application resources (Parts 101...199) extend the generic resources to support the needs of specific groups of applications; for example, Part 101 “Draughting” defines the common data requirements of all applications that incorporate or make use of engineering drawings. The Integrated Resources provide the developers of STEP Application Protocols with standard definitions of product data; they are not themselves intended for direct implementation. In this respect they may be loosely compared to a collection of library routines used by programmers: Integrated Resources define reusable components that are intended to be combined and refined (within an Application Protocol) to meet a specific need. Six parts in the integrated resources series are included in the initial release of STEP: • Part 41 “Fundamentals of product description and support”; • Part 42 “Geometric and topological representation”; • Part 43 “Representation structures”; • Part 44 “Product structure configuration”; • Part 46 “Visual presentation”; • Part 101 “Draughting”. Several other Integrated Resource parts have been developed for later publication, as required to fulfil the requirements of new Application Protocols. 58 STEP for data management, exchange and sharing Application protocols By far the largest, and in many senses the most important class of parts is the Application Protocols class. Application Protocols are numbered from part 201 onwards; two Application Protocols are included in the initial release of STEP: • Part 201: Explicit draughting; • Part 203: Configuration controlled design. Many others are being developed for later publication. Application Protocols define and fulfil the requirements of an identified application of product data related to a specific industry need. This should be contrasted with the generic, application-independent nature of the Integrated Resources. It is noted above that Part 42 of STEP defines standard representations of geometry: an Application Protocol will, for example, define how these representations are used to exchange the designed shape of the wing of an aeroplane, or the inservice shape of the hull of a ship, or the shape of the access area around a pump within a petro-chemical plant. These are examples of uses of shape that may be supported by appropriately designed Application Protocols. Part 1 of STEP defines an Application Protocol as: “a part ... (of ISO 10303) ... that describes the use of integrated resources satisfying the scope and information requirements for a specific application context.” This definition highlights a key characteristic of Application Protocols: they are uses of the STEP Integrated Resources, but do not extend the data model defined in the Integrated Resources. This characteristic ensures a high degree of uniformity across different Application Protocols, ensuring that common or similar requirements are satisfied using a common or similar solution. The role of an Application Protocol is to provide the basis for implementations of STEP, and to enable the assessment of conformance of implementations. As noted in Chapter 2, Application Protocols were introduced into IGES as a mechanism for defining controlled, meaningful subsets within the standard. STEP has extended and refined this concept considerably, and the development of STEP is now focused on the development of Application Protocols to meet the requirements of a wide range of industry sectors and application areas. The structure and content of STEP 59 Clearly, this diversity has to be managed: otherwise, STEP would consist of a collection of separate, industryor discipline-specific Application Protocols. The costs of implementing and supporting these would be very high as new interfaces would have to be written from scratch for each Application Protocol. However, the diversification of Application Protocols is not only managed; it is a conscious design intent of STEP that Application Protocols should be consistent. This consistency is a

TL;DR: A comprehensive descriptive model of R&D knowledge management is presented and its use illustrated, and it is applied in a case study concerning a Dutch multinational in the chemical industry.
Abstract: In this article, a comprehensive descriptive model of R&D knowledge management is presented and its use illustrated. Knowledge is defined as: information internalized by means of research, study or experience, that has value for the organization. First, the issue of knowledge management is placed in the context of R&D management, and set alongside what has been written in R&D management literature about topics such as information management, information technology in R&D, technology transfer, communication and organizational learning. Then, we present our descriptive model, and apply it in a case study concerning a Dutch multinational in the chemical industry. The model served as an aid to identify bottlenecks, and was a useful starting point for formulating improvement plans, some of which are presented. The paper concludes with an evaluation of the model as a communication and analysis tool, and ideas for further improvement.

TL;DR: In this article, the authors argue that instead of using an exist-ing tool in a new application, it is better to embed reusable components in orderto make the resulting system more re-sponsive.
Abstract: The field of database systems researchand development has been enormouslysuccessful over its 30-year history. Ithas led to a $10 billion industry with aninstalled base that touches virtually ev-ery major company in the world. Itwould be unthinkable to manage thelarge volume of valuable informationthat keeps corporations running with-out support from commercial databasemanagement systems (DBMSs).Today, the field of database researchis largely defined by its previous suc-cesses, and much current research isaimed at increasing the functionalityand performance of DBMSs. A DBMS isa very complex system incorporating arich set of technologies. These technolo-gies have been assembled in a way thatis ideally suited for solving problems oflarge-scale data management in the cor-porate setting. However, a DBMS, likeany large tool, places some require-ments on the environment in which it isbeing used. The DBMS imposes someexecution overhead, often requires afairly high level of expertise to installand maintain, and only manages datathat is in fairly specific file formats.At the same time, the data that needsmanaging is changing radically and isbeing stored in places other than data-base systems (e.g., files). It is also ob-tained in large volumes from externalsources, like sensors. While the trend ofbuilding more powerful database man-agement systems has a place, there isalso a need for data management incontexts that cannot cope with the over-head of a full-blown DBMS; many envi-ronments call for a much lighter-weightsolution.Sometimes, instead of using an exist-ing tool in a new application, it is betterto embed reusable components in orderto make the resulting system more re-sponsive. In some cases, it is the tech-niques that a tool embodies that aremost reusable. We argue that this ob-servation is true in many new data-intensive applications. We would like toreuse database system components, butwhen that is inappropriate we must bewilling to reuse our techniques and ourexperience in new ways.If we look around at information thatpeople use, we see many examples inwhich database systems are conspicu-ous by their absence.

TL;DR: In this article, a data communication manager provides a versatile interface between different types of scanners and a central computer system, where each data manager periodically receives loading data from the host computer and transmits the appropriate signal to the load/no-load indicator via another RF link.
Abstract: A data communication manager provides a versatile interface between different types of scanners and a central computer system. Each data manager periodically receives loading data from the host computer. A scanner is used to read package tracking numbers on packages at a predetermined point in a hub facility. The data is transmitted from the scanner to the data manager via radio frequency (RF) link. The data manager uses stored disposition data (received from the host earlier) to determine whether the package should be loaded and transmits the appropriate signal to the load/no-load indicator via another RF link. The data manager stores data indicative of the disposition of the package data in its memory and also forwards the data to the host computer, where it may be used for tracking purposes. The data communication manager provides a "smart" data manager that reduces the amount of traffic on the host computer's network and provides sub-second response times to a loader. The application programs and data in the data managers may be updated by the host as needed.

TL;DR: This paper outlines some of the issues with respect to authorization management and specification and to access control enforcement and illustrates the basic ideas of possible authorization model for the protection of information in federated systems.
Abstract: One of the new emerging technology for data management is today represented by federated systems. The success of this technology, which has been receiving increasing attention from researchers and developers, comes from the need to integrate and work on diflerent existing systems independently developed and evolved. The necessity of making them atlailable to users as if they were a single system while at the same time not affecting their independent working arises several issues with respect to authorization management and specification and to access control enforcement.

TL;DR: The evolution of data management systems is sketched, arguing that multimedia databases will be a cornerstone of cyberspace and allow fast, reliable, and secure access to globally distributed data.
Abstract: Computers can now store all forms of information: records, documents, images, sound recordings, videos, scientific data, and many new data formats. Society has made great strides in capturing, storing, managing, analyzing, and visualizing this data. These tasks are generically called data management. This article sketches the evolution of data management systems. There have been six distinct phases in data management. Initially, data was manually processed. The next step used punched-card equipment and electromechanical machines to sort and tabulate millions of records. The third phase stored data on magnetic tape and used stored-program computers to perform batch processing on sequential files. The fourth phase introduced the concept of a database schema and on-line navigational access to the data. The fifth step automated access to relational databases and added distributed and client server processing. We are now in the early stages of sixth-generation systems that store richer data types, notably documents, images, voice, and video data. These sixth-generation systems are the storage engines for the emerging Internet and intranets. Early data management systems automated traditional information processing. Today they allow fast, reliable, and secure access to globally distributed data. Tomorrow's systems will access and summarize richer forms of data. It is argued that multimedia databases will be a cornerstone of cyberspace.

TL;DR: The impetus for developing the interactive ground-water modeling system was the relative lack of tools that fully integrate models with GIS and the potential benefits to the resource manager in developing such integrated environmental modeling systems.
Abstract: During the last several years, the geographic information system (GIS) technology has emerged as an extremely effective tool for analyzing and prioritizing natural resource management alternatives. Because natural resource management problems are spatial in nature, the GIS technology provides a tool for defining the extent of the problem, and facilitates the design and implementation of alternative management strategies. The flexible design of a GIS coupled with the ability to integrate models with spatial data gives resource managers and planners the tools to effectively manage natural resources and to assess the implementation of regulatory policies before they are implemented. This paper describes an interactive modeling system developed within a GIS environment to facilitate rapid appraisal of the susceptibility of ground water to contamination by pesticides. The interactive system combines three widely used screening models with the ARC/INFO GIS software and a graphical user interface. Implemented on a color-graphic engineering workstation, the interactive modeling system can be used to visualize the spatial distribution of model inputs and outputs. The advantage of this system is that instead of ad-hoc linkage between GIS software and a simulation model, a fully integrated and interactive system in which the model equations are programmed within the GIS was developed. The impetus for developing the interactive ground-water modeling system was the relative lack of tools that fully integrate models with GIS and the potential benefits to the resource manager in developing such integrated environmental modeling systems. There is an increasing demand, from the GIS perspective, for tools that perform functions other than organization and display of spatial data. From the ground-water modeling perspective, several advantages can be derived from fully integrating process-based models with the data management, analysis, and display capabilities of the GIS.
