Being able to run applications written in a single language on multiple platforms is a strong incentive for migrating applications to the web. This along with the possibility to avoid the sometimes problematic procedure of installing software, makes the case even stronger. This thesis investigates how to migrate a workflow graph editing system into a web technology in order to publish it on the web. We will evaluate a number of different technologies such as WebGL, HTML5 canvas and SVG. SVG is deemed as the preferred technology due to its advantages when it comes to interaction. As it can leverage JavaScripts event system we get a potent way of handling events without writing a single line of code. When combining this with the framework D3JS we achieve a great tool for writing workflow management systems.

ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / With the development of Internet and the urgent need for GIS (Geographic Information System), XML (eXtensible Markup Language) provides a powerful new way for new web application. This paper makes a research on the application of SVG based on XML in the WebGIS (World Wide Web Geographical Information System). In this paper, the characteristics of XML are illuminated in short; the application of XML in WebGIS is discussed and the features of SVG and its usage with XML are presented; a design of SVG based on XML in the WebGIS system is given.

GIS (Geographic Information Systems) is gradually mature on the Internet, and the applications of the GIS, such as: living, entertainment, traffic, environment etc., are more extensive. People are very easy to get useful spatial information from Web GIS. SVG (Scalable Vector Graphics) was initiated by W3C (World Wide Web Consortium), it is an XML (eXtensible Markup Language)-based two-dimensional vector graphics standard on the internet. It is suitable to be used on the Web GIS. The research focuses on XML-based Web GIS including: spatial information and attribute data. The process to create a SVG system is discussed. Besides to write a software code for implementing a SVG system as a Web GIS, some functions were added to the system to promote the operating efficiency. Finally, two query applications were set up. One is Tapeng Bay to display fundamental setting up process and the other is Taipei school information query system to test the functions for SQL and statistical information. Keywords: Web GIS, XML, SVG, DOM

Using the World Wide Web of today, searching for a graphic pertaining to a particular subject domain or in response to a specific query is a difficult task. A typical search for a graphic related to a specific subject matter or query may yield hundreds or thousands of Web resources, few of which relate to the intended meaning. The primary goal of the completed dissertation is to develop and assess the feasibility of using a global ontology for Scalable Vector Graphics (SVG) written in the Semantic Web markup language Web Ontology Language (OWL). SVG is an eXtensible Markup Language (XML) based technology used to describe two-dimensional graphics. SVG has the ability to fully scale images without loss of resolution, provide file sizes that are independent of resolution, represent text as text strings allowing the graphic to be fully searched for content, and support a rich set of geometrical primitives. An SVG OWL ontology provides three benefits. First, the ontology enables powerful semantic search engines to quickly and efficiently pinpoint SVG graphics and relate these graphics to specific knowledge domains. Second, the ontology enables semantic search engines to understand the content of a SVG graphic and infer relationships between the content of the graphic and specific domains. Lastly, enabling SVG graphics to be annotated in varying levels of abstraction allows the graphic to be reused in other contexts. The research methods included developing the framework for the model, identifying the entities to be used in the ontology, representing the conceptual elements using Unified Modeling Language (UML), converting the UML to OWL, evaluating the ontology to ensure that it meets the requirements initially presented, developing a working system based on the ontology and testing this system, and documenting the development process. Regarding experimental results, a total of 69 queries were applied to a set of 500 images representing a range of both primitive and derived spatial properties. Both recall and precision were perfect, indicating the feasibility of effective ontology-based search for annotated vector graphics through this approach. The question of scalability to more complex and realistic settings remains for future research.

This thesis addresses a research programme that aimed to provide an open standard methodology for publishing Brazilian local primary school atlases on the World Wide Web. It also aims to contribute to the use of computer laboratories provided to Brazilian primary schools by the Brazilian government. Using a local school atlas as the source of information, a Web-based prototype of the School Atlas of Rio Claro (SP) was developed in SVG (Scalable Vector Graphics). SVG is a vector-based standard for publishing interactive graphics on the Web validated by the Web Consortium. This prototype was tested with a group of Brazilian primary school teachers. The test was conducted with fourteen teachers, all of them were familiar with the paper version of the School Atlas. During weekly meetings, the participants took notes to discuss and reflect about the practices held in school with local maps. The main test carried out with teachers was to prepare a paper activity based on the atlas content. The idea behind this activity was to foster teachers to leave a passive role as mere users and interact with the product in a more active fashion. In order to enable them to take full advantage of simple digital tools they were briefly trained to capture screen, use image editing software (they were instructed on the use of Paint, an image editing application available in Windows), and to copy text from the atlas. The results demonstrated that the teachers were keen to interact with the product and, although reproducing some common practices of paper atlas use, they revealed a deep interest on the use of the Internet as a medium for education and the prototype itself. A second test was carried out with a group of atlas developers. They were given a time frame of two weeks to develop an SVG-based atlas using the methodology proposed in this research. They completed the task within the time frame proposed however they indicated that more specific training should be desirable; this finding indicates the need to introduce digital map publishing as a subject to be taught in geosciences undergraduate courses in Brazil. It is believed that open standard methodology proposed here can be applied to other cities also developing local atlases for early geographical education.
