The document discusses the Open Archives Initiative's Object Re-Use and Exchange (OAI-ORE) effort. OAI-ORE aims to develop standards and protocols to facilitate discovery, referencing, access, aggregation, and processing of complex digital objects across repositories. It takes a web-centric approach, seeing digital objects as compound information objects that may have multiple representations. The standards aim to address challenges like consistently linking related objects and enabling discovery of all parts of an object. The talk outlines motivations, examples, and design considerations for OAI-ORE's work on these challenges.
