As XML is used by standard format for information expression and information exchange in various field, Many Company began to use SVG by user interface or information expression tool of embedded system such as mobile phone based wireless internet. Because SVG has many additional information to keep structure of SVG document exception real data, there is a problem that transfer time of SVG file is so cost for quantity of transmitted data actually. To solve this problem, many researches using compression conception have been conducted for applying to an embedded system. This paper proposes SMETA that can use existing researches using compression concept at once. SMETA divides SVG file to each part that can allocate meaning, and gives semantic metadata to each part without alteration of SVG structure. SMETA can reduce site of transmitted SVG file actually by transmitting specification part of SVG file that metadata does not agree or has unlisted part in an embedded system between an embedded system and server, before transmit whole SVG file. By size of transmitting SVG file is decreasing, transfer time can be shortened accordingly.

A rapid development of Internet is changing users' desire from existing static contents to dynamic and diverse ones. Thus the SVG provides more affluent and sophisticated graphic expressions than an existing method based on bitmap, it can faithfully display vector graphics without scarifying any functions or the problem of device compatibility. In addition, it allows indexing, searching, storing, and sharing by the description of the logical structure of graphics. Since there are, however, very few people who know the complex SVG syntax and make use it, an editing system, which enables users to utilize the SVG graphics easily, has been in need. Therefore, in this thesis, we do research on basic technology on the SVG, design and make an editing system for SVG documents. The system, therefore, provides uses with a user-friendly editing interface and enables them to write graphic objects easily, and generates complex SVG documents automatically.

기존의 SVG 파일은 모바일 디바이스에 맞추어 제작하더라도, 디바이스에 따라 사이즈 조절이 되지 않아, 이미지가 전체적으로 보여지지 않는다. 그래서 각 SVG 파일을 해당 디바이스의 디스플레이에 맞춰서 다시 제작해야하는 어려움이 있다. 본 논문에서는 위의 문제점을 해결하기 위해 SVG Trans-Gateway를 제안한다. 이 SVC Trans-Gateway는 모바일 디바이스 기준으로 데스크탑 PC에서 제작된 SVG 파일을 요청하는 해당 디바이스의 정보를 분석하여, 각 디바이스의 디스플레이에 맞추어 변환해주는 게이트웨이 이다. 그래서 이 시스템은 각 디바이스의 화면 해상도에 따라, 동일한 SVG 파일을 변환해주는 기능을 수행한다.

기존의 아바타 시스템은 GIF 파일 기반으로 한정된 아바타 캐릭터를 이용하여 다양한 표현이 제한적이었다면 SVG 파일을 기반으로 하는 아바타 시스템의 경우 사용자가 능동적으로 아바타를 수정할 수 있어 다양한 아바타 캐릭터를 만들 수 있는 장점이 있다. 또한 기존 시스템은 아바타를 위한 GIF파일의 구성 정보만 유지하고 있었다면 SVG 파일 기반의 아바타 시스템의 경우 각 사용자별로 아바타를 표현하는 별도의 SVG 파일을 가지며. 사용자가 각 개인의 아바타를 수정함으로서 갱신 연산이 빈번하게 발생한다. 이에 효과적인 갱신 연산을 수행하는 SVG 파일을 저장하는 저장소가 필요하다 SVGStore는 각각의 아바타에 대응하는 SVG 파일을 저장하고 빈번한 갱신 연산을 효율적으로 제공한다.

Svg(Scalable Vector Graphics) is xml graphic standard recommended by E3C as a language based on xml to express two-dimension graphic. Svg can accommodate all Xml's patency and advantage of interoperability, and can used as various web applications being combined with other xml language. In addition, Svg can be applied to the fields of electronic commerce, geographical information, computer education and advertisement because it can produce high quality of dynamic from real-time data. SVG's application can be enhanced by linking with database. In this paper, we discuss how Svg can be utilized in theater reservation system, not just explaining svg's meaning or ability. Svg added graphic advantage in addition to xml's advantage. This means that svg retains not only graphic element but also xml's softness. It becomes easier to designate seats and add them. Current reservation system provided in general only information on time and price for a ticket, but the system using SVG in this paper provides additional information on position, price, cancellation and purchase availability of seat.

Electronic Navigational Charts(ENCs) are official nautical charts which are equivalent to paper charts with supplementary information. Although their main purpose is to be used for the safe navigation of ships, they also contain much information on coasts and seas which may be interesting to ordinary people. However, there is no easy way to access them because of therir specialized data format, access method and visualization. This paper proposes on implementation of SVG for the access and services of ENCs. SVG(Scalable Vector Graphic) makes it possible to make use of Vector graphics for servicing maps in basic internet browsing environment. Implement of SVG for ENC applications by this research is free of special server side GIS mapping system and client side extra technology. The implementation of SVG for ENC Applications can be summarized as follows: Firstly, SVG provides spatial information to possess searching engine to embody SVG map. Secondly, SVG can provide high-quality vector map graphics and interactive facility without special Internet GIS system. It makes it possible to use services with very low cost. Thirdly, SVG information service targeting on maritime transportation can be used as template, so it can be used dynamically any other purpose such as traffic management and vessel monitoring. Many good characteristics of SVG in mapping at computer screen and reusability of SVG document provide new era of visualization of marine geographic information.

Development of internet had centered on that offer universality of expression. But, graphic processing of expression center has many inconveniences because of method that is not structural in World Wide Web. Announced SVG that is XML application to permit efficient expression and storage of vector graphic expression, share in W3C to supplement these things. Therefore, because using SVG document in this treatise, edit vector graphic through interface that could edit expressed graphic object directly structural edit and screen that is offered in graphic edit system form and designed SVG edit system to express. This system may use usefully to efficient XML graphics processing on the GIS system and Mobile service environment and so on.

인터넷의 급속한 발전은 기존의 정적인 웹을 탈피하여 사용자들로 하여금 더욱더 동적이고 다양한 콘텐츠를 요구하는 형태로 바뀌어 가는 실정이다. 따라서 이러한 사용자들의 욕구를 충족시키기 위해 인터넷 상에서 표현의 고급화와 체계적이고 구조적인 방식의 콘텐츠를 생성하고 관리하기 위한 방법들이 논의됨에 따라 이를 충족시키기 위한 방법으로 W3C(World Wide Web Consortium)에서는 SVG(Sealable Vector Graphics)를 제안하였다. SVG는 기존의 인터넷에서 사용되던 비트맵 기반의 디스플레이 보다 훨씬 풍부하고 정교한 그래픽 표현을 제공하기 때문에 기능이나 장지 호환성의 희생 없이 완전하게 벡터 그래픽을 표현한다. 또한. 그래픽에 대한 논리적인 구조를 기술함으로써 인덱싱, 검색, 저장 또는 공유가 가능하도록 정의하고 있다. 이에 본 논문에서는 SVG에 관한 기초기술 연구 및 구조화된 SVG 문서를 사용자 중심의 편집 인터페이스를 통해 일반 사용자들이 손쉽게 그래픽 객체를 직접 저작함에 따라 복잡한 SVG 구문을 자동으로 생성하는 SVG 문서 저작 시스템을 설계 및 구현한다.

GeoWeb services deliver various thematic information related to geographic positions over the internet GeoWeb services needs to provide efficient accessibilities to geographic contents by interaction with users through the map graphic elements. SVG, which is an application of XML, gives rich DOM I/F for interaction with graphic objects. In this study map servers and client viewers are implemented to serve SVG map available on the fixed mobile internet computing environments. Map servers are made compliant with OGC WMS and WFS specifications and SVG map viewers are developed for both Windows PC and WinCE PDA.
