Abstract
Scalable Vector Graphics (SVG) is an XML‐based vector graphics standard developed by the World Wide Web Consortium. The National Archives of Singapore recently launched an online virtual exhibition, Colours in the Wind, which was developed using Macromedia Flash, the most widely used format for animated and interactive vector‐based Web content. The current work reports on the experiences in developing an SVG‐based version of this exhibition as well as the exploration of SVG's potential for developing future virtual exhibitions as an alternative to Flash. Observations from the SVG effort are discussed together with descriptions of techniques used and the limitations and problems that SVG poses to developers. A comparative study involving the usability features of the Flash and SVG versions of the virtual exhibition is also described. Results indicate that users are positive towards SVG and suggest the viability of the technology as a development platform.

Abstract
Purpose
The purpose of this paper is to is to describe vector graphics for web lectures, focusing on the experiences with Adobe Flash 9 and SVG.
Design/methodology/approach
The paper presents experiences made during the development and everyday use of two versions of the lecture‐recording system virtPresenter. The first of these versions is based on SVG, while the second is based on Adobe Flex2 (Flash 9) technology. The paper points out the advantages vector graphics can bring for web lectures and briefly presents a hypermedia navigation interface for web lectures that is based on SVG. The paper also compares the formats Flash and SVG and concludes with describing changes in workflows for administrators and users that have become possible with Flash.
Findings
Vector graphics are an ideal content format for slide‐based lecture recordings. File sizes can be kept small and graphics can be displayed in superior quality. Information about text and slide objects is stored symbolically, which allows texts to be searched and objects on slides to be used interactively, for example, for navigation purposes. The use of vector graphics for web lectures is, however, a trend that has begun only recently. A major reason for this is that multiple media formats have to be combined in order to replay video and slides.
Originality/value
The paper offers in insight into vector graphics as an ideal content format for slide‐based lecture recordings.

Abstract
Purpose
The purpose of this paper is to describe the case of synchronized multimedia presentations.
Design/methodology/approach
The proposal is based on SMIL as composition language. Particularly, the paper reuses and customizes the SMIL template used by INRIA on their technical presentations. It also proposes a set of free tools to produce presentation content and design focusing on RealPlayer as delivery client. The integration in this e‐learning platform of multimedia compositions developed following the proposed technique is also presented.
Findings
Technological support to learning and teaching has become widespread due to computers and internet ubiquity. Particularly e‐learning platforms permit the any‐time‐and‐any‐place distribution of interactive multimedia learning materials. There are commercial tools available to author this kind of content, usually based on proprietary formats. This option has some drawbacks like license cost and software company dependency. To use open data standards and free software is an alternative without these inconveniences but available authoring tools are commonly less productive. This shortcoming is certainly important to non‐technical authors and it could be solved by open source collaboration.
Originality/value
The paper presents multimedia learning material using open standards and free software.

Abstract
Within the library world, there is a growing interest in the use of XML in journals, not least because of its implications for e‐journal archiving. But what is actually happening in the commercial journals market? How far have XML and its related standards permeated the production of real commercial journals and how do publishers and other providers of journals see this area developing? This paper looks at the activities and future plans of a selection of publishers and aggregators in the STM journals market, although many of the comments relate to the entire journals arena.

Abstract
The rapidly emerging of Mobile Internet and the constantly increasing of wireless subscribers' number bring new opportunities and challenges to geographic information sharing and accessing. Current Web GISs, which are accessed by using connection based approaches, are very inefficient in fulfilling the requirements of GIS applications under open, dynamic, heterogeneous and distributed computing environments such as (Mobile) Internet. In this paper, we propose a new system for accessing and sharing distributed geographic information by using mobile agent and GML technologies, in which mobile agents are used to overcome the limitations of traditional distributed computing paradigms in (mobile) Internet context and GML is adopted as the common format for spatial information wrapping and mediation, while SVG is used as a web‐map publishing format that can be processed and displayed in Web browser. A prototype is implemented, which demonstrates the effectiveness and feasibility of the proposed method.

Purpose
To provide a technical and practical analysis of the interactive floor plan developed by and for the law library at the Catholic University of Leuven, Belgium.
Design/methodology/approach
The different steps in the development process are described, from original idea to conclusion.
Findings
Though some steps in the process are described fairly technically and detailed, the paper is by no means a step‐by‐step guide to developing similar applications, it briefly touches the principles and concepts that make the application work.
Originality/value
This paper describes the conception and development of a new type of library application. A truly interactive floor plan, unlike traditional static floor plans found on most web sites, was developed to create an actual virtual library. The concepts and techniques described in this paper could prove useful for other libraries wanting to create a similar application.
