Object Graphs as Pivotal Representations for Hypermedia

This position paper advocates a possible bridging of multiple heterogeneous formats and interfaces for hypermedia data and metadata. Rather than one more text, bit-stream or procedural script format, a language-neutral graph of linked objects is proposed as a high-level pivotal representation model. A suitable distributed object platform provides the underlying implementation and communication medium for node objects. Different projections of the global object graph may be mapped to different representation domains, while node objects of different granularities may implement all related, semantic, structural or programmatic information. Bulk media content itself may be conveyed separately under standard stream/file formats, for which higher-level objects act as proxies. This proposal has been validated by implementing, on top of the Java
