A study on the component classification in GIS (Geographic Information System)
4. Prototype of GIS Component Retrieval System on line
In this paper, the prototype of GIS component retrieval system is presented to register new component and manage them and retrieval related component effectively. Fig. 3 shows the prototype of Web based GIS component retrieval system. To operate this retrieval system, the non-functional GIS component classification, metadata of each GIS, is used.  Figure 3 The Prototype of GIS Component Retrieval System 5. Conclusion In order to increase reusability higher, a large sized collection of reusable software is a necessity. Recently, most research efforts have been focused on not only the construction of repository that contains a large number of components but also define metadata well to retrieval. In this paper, to operate GIS Component Retrieval System, two types non-functional component classifications in GIS are proposed; 1) GIS content-dependent metadata, 2) GIS content-independent metadata. Also, the detail metadata item for each are defined. In the future, in order to increase component reusability in GIS domain, these should be consideration for GIS component repository management system using not only metadata described here but also further extended metadata.
