Joined View Editor for Mashups of Web Data Stores

摘要

Recent years have witnessed the emergence of Web services that publish data that can be used as globally shared data resources, and Web data stores offer data resources that can be shared and modified by users or groups. We think associative data representation among Web data elements is important for the reuse of the data for various purposes even when treating personal/group data. This paper aims to provide a general-purpose widget for Web data browsing/editing where users can easily create and update their data elements that are associated with other data elements, and proposes a table editor for joined views of Web services. With our editor, the user can join multiple Web services, and edit the left/right elements on the joined view in a tabular grid. To support easy manipulation of associated data during the modification, our editor continuously provides the renewed view reflecting the modification. The user can also try out multiple modifications while checking their impact on the view, and decide later whether to commit the modifications to the Web data stores or to discard the modifications. This paper presents some illustrations that demonstrate the use of this joined view editor, discusses the design, and briefly describes its implementation.
