MoST: a 3D web architectural style for hybrid model data

Abstract

Within this paper, we present a novel 3D web architecture style which allows to build format-agnostic 3D model graphs on the basis of ReSTful principles. We generalize the abstract definitions of RFC 2077 and allow to compose models and model fractions while transferring the "Media Selection URI" to a new domain. We present a best practice subset of HTTP/HTTPS and ReST to model authorization, data change, and content format negation within a single efficient request. This allows implementations to handle massive graphs with hybrid format configurations on the very efficient HTTP transport layer, without further application intervention. The system should be attractive to platform and service providers aiming to increase their ability to build 3D data application mashups with a much higher level of interoperability. We also hope to inspire standardization organizations to link generic "model/*" formats to RFC 2077 defined semantics like "compose".
