DESCRIPTORS *Computer System Design; *Design Requirements; Education; Educational Media; Educational Resources; Educational Technology; *Electronic Libraries; Information Systems; *Instructional Design; Instructional Materials ABSTRACT This implementation paper introduces principles for the information architecture of an educational digital library, principles that address the distinction between designing digital libraries for education and designing digital libraries for information retrieval in general. Design is a key element of any successful product. Good designers and their designs put technology into the hands of the user, making the product's focus comprehensible and tangible through design. As straightforward as this may appear, the design of learning technologies is often masked by the enabling technology. In fact, they often lack an explicitly stated instructional design methodology. While the technologies are important hurdles to overcome, the report advocates learning systems that empower education-driven experiences rather than technology-driven experiences.

Trant, University of Toronto / Archives & Museum Informatics 158 Lee Ave, Toronto, ON Canada M4E 2P3 jtrant [at] archimuse.com Abstract This paper reviews research into social tagging and folksonomy (as reflected in about 180 sources published through December 2007). Methods of researching the contribution of social tagging and folksonomy are described, and outstanding research questions are presented. This is a new area of research, where theoretical perspectives and relevant research methods are only now being defined. This paper provides a framework for the study of folksonomy, tagging and social tagging systems. Three broad approaches are identified, focusing first, on the folksonomy itself (and the role of tags in indexing and retrieval); secondly, on tagging (and the behaviour of users); and thirdly, on the nature of social tagging systems (as socio-technical frameworks). Keywords: Social tagging, folksonomy, tagging, literature review, research review 1. Introduction User-generated keywords – tags – have been suggested as a lightweight way of enhancing descriptions of on-line information resources, and improving their access through broader indexing. “Social Tagging” refers to the practice of publicly labeling or categorizing resources in a shared, on-line environment.

  • The Role of Information Architecture in Designing a Third-Generation Library Web Site
    The Role of Information Architecture in Designing a Third-Generation Library Web Site Jennifer Duncan and Wendy Holliday Library Web sites have evolved over the past decade, from simple pages with a few links to complex sites that provide direct access to hundreds of different resources.

  • Chapter 1 Web Basics and Overview
    Chapter 1 Web Basics and Overview The Web is an Internet-based distributed information system. Anyone with a computer connected to the Internet can easily retrieve information by giving a Web address or by simply clicking a mouse button. The Web is a great way to disseminate information and making it available 24/7. Information can also be collected from Web users and customers through online forms. Maintainers and administrators can control and update Web content from anywhere on the Web. All these make the Web a powerful tool for mass communication, e-business and e-commerce. Compared with TV, radio, news papers, and magazines, putting the word out on the Web is relatively simple and inexpensive. But a website is much more than such one-way communication media. It can be a virtual o±ce or store that is always open and supported by workers from anywhere. Web service companies o®er free Web space and tools to generate simple personal or even business Web pages. But, well-designed and professionally implemented websites are much more involved. Even then, expertly produced websites are still much more cost-e®ective than other means of mass communication. For business and commerce, the cost of a website is negligible when compared to building and operating a brick-and-mortar o±ce or store. Once in-place, a website is a store that never closes and that is very attractive. People take great pains in building an o±ce or store to project the right image and to serve the needs 7 8 CHAPTER 1.

  • Using Ontologies for Enterprise Architecture Model Alignment
    Using Ontologies for Enterprise Architecture Model Alignment Gon¸caloAntunes1, Artur Caetano1;2, Marzieh Bakhshandeh1, Rudolf Mayer3, and Jos´eBorbinha1;2 1 Instituto Superior T´ecnico, University of Lisbon, Av. Rovisco Pais 1, 1049-001 Lisboa, Portugal, 2 Information Systems Group, INESC-ID, Rua Alves Redol 9, 1000-029 Lisboa, Portugal, 3 SBA Research, Favoritenstraße 16, 1040 Wien, Austria {goncalo.antunes,artur.caetano}@ist.utl.pt Abstract. One of the primary goals of enterprise architecture aligning the business with the underlying support systems. An architecture de- scription encompasses an heterogeneous spectrum of domains, such as business processes, application components, metrics, people and tech- nological infrastructure. Views express the domain elements and their relationships from the perspective of specific concerns relevant to the system stakeholders. Thus, each view needs to be expressed in the de- scription language that best suits its concerns. However, enterprise ar- chitecture languages often specify meta-models that cross-cut distinct architectural domains. This hinders extensibility and adds complexity to the language. Ob the other hand, describing each domain through a specialized language and then integrating the multiple languages raises challenges at the level of traceability and consistency. This paper pro- poses using ontologies to integrate different enterprise architecture do- mains and to analyse the resulting models. This goal is realized through a core domain-independent language that is extended by several domain- specific languages, each focussing on a set of specific concerns. The ap- proach contributes to the alignment of the different domains while en- suring traceability and model consistency. The proposal is demonstrated through an evaluation scenario that employs ArchiMate as the domain- independent language extended with a set of domain-specific languages.

  • Integrating Blockchain with Erp for a Transparent Supply Chain
    PERSPECTIVE INTEGRATING BLOCKCHAIN WITH ERP FOR A TRANSPARENT SUPPLY CHAIN Abstract Supply chain is complex today. Multi-echelon, highly disjointed, and geographically spread are some of the cornerstones of today’s supply chain. All these together with different governmental policies and human behavior make it almost impossible to probe incidents and trace events in case of supply chain disruptions. In effect, an end-to-end supply chain, from the most basic raw material to the final product in a customer’s possession, is opaque. The inherent cost involved in managing supply chain intermediaries, their reliability, traceability, and transparency further complicate the supply chain. The solution to such complicated problems lies in improving supply chain transparency. This is now possible with the concept of blockchain. The usage of blockchain in a financial transaction is well known. This paper reviews blockchain technology, which is changing the face of supply chain and bringing in transparency and authenticity. This paper first discusses the history and evolution of blockchain from the bitcoin network, and goes on to explore the protocols. The author takes a deep dive into the design of blockchain, exploring its five pillars and three-layered architecture, which enables most of the blockchains today. With the architecture, the author focuses on the applications, use cases, road map, and challenges for blockchain in the supply chain domain as well as the synergy of blockchain with enterprise applications. It analyzes the integration of the enterprise resource planning (ERP) system of the supply chain domain with blockchain. It also explores the three distinct growth areas: ERP-blockchain supply chain use cases, the middleware for connecting the blockchain with ERP, and blockchain as a service (BaaS).
