- Description:
- A proposal for a presentation given at the Open Repositories conference in 2015 held in Indianapolis described thus, One of the many successes of the Hydra community is the fundamental notion from which its name is derived—the concept of many interfaces (“heads”) over top of a single repository (the “body”). The recent release of Fedora 4, with its internal RDF-centric model, has spurred efforts for a community-wide model of collections and works, such that the heads can be sure that the body will behave as they expect it to. That model has been designed and vetted by the Hydra community, and its architecture and initial implementations will be presented in this paper. [Note, and the subject of this proposal has since become known as the 'Portland Common Data Model'.]

- Description:
- A workshop delivered at Hydra Connect 2016, described thus, increasing familiarity with PCDM, contributing back to PCDM from the activities of the participants, and increasing participants’ familiarly and comfort with data models more broadly., and The Portland Common Data Model (PCDM) is a flexible shared, linked data-based domain model for representing complex digital objects. This workshop will review PCDM, its history, technical overview, recent developments, and Hydra-specific implementation considerations. The workshop will also include an interactive modeling session where users will employ use cases from their repositories (or provided samples) to model in PCDM. The goals of the workshop include
