We introduce CHIME, the Columbia Hypermedia IMmersion Environment, a metadata-based information environment, and describe its potential applications for internet and intranet-based distributed software development. CHIME derives many of its concepts from Multi-User Domains (MUDs), placing users in a semi-automatically generated 3D virtual world representing the software system. Users interact with project artifacts by “walking around” the virtual world, where they potentially encounter and collaborate with other users’ avatars. CHIME aims to support large software development projects, in which team members are often geographically and temporally dispersed, through novel use of virtual environment technology. We describe the mechanisms through which CHIME worlds are populated with project artifacts, as well as our initial experiments with CHIME and our future goals for the system.
