A high-level visual language for generating web structures

In earlier work, we discussed using data encapsulation to provide integrated access to large amounts of heteroge-neous information through WWW browsers. Here, we de-scribe a visual data modeling language which supports the generation of metadata entities to encapsulate raw data. A prototype version of an interpreter for our interactive Visual Repository Definition Language (VRDL) is now operational and may be used for building and maintaining information repositories. 1
