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'.]

Using Sufia 7 as a reference model, what does the path for depositing a new item into a Hydra/PCDM based repository look like from an end-user, code, console, solr, and fedora perspective, A presentation given at Hydra Connect 2016 described thus, show the upload of new digital content via the Sufia UI and show each step of the data flow in the Browser, rails console, and Fedora. Walk through derivative generation and show the various PCDM relationships being built at each stage. Then add a new user collection, and walk through the same flows as a work is added to a collection, and what gems are in play, what does the data look like from a ruby developer perspective, what is persisted in Fedora and Solr - how does it all relate to PCDM? A video of this session is available at the 'Related URL' below.

GeoConcerns is a plugin to CurationConcerns for managing geospatial resources in a repository (http, A presentation at Hydra Connect 2016 described thus, and //geoconcerns.github.io). This presentation will give an overview and demonstration of GeoConcerns’ features and PCDM-based data model. In addition, we will discuss the code base and future development work such as integration with Sufia. An audio recording of the session is available for download below.

I will show the data model migration from Sufia 6 to Sufia PCDM we used for ScholarSphere. In addition I will the outline major design decisions we made along the way. Then we will look at the tools in Sufia for migration of data from Sufia 6 to Sufia PCDM. I will include examples of extending the functionality for people who have extended the basic Sufia 6 model. An audio recording of the session is available for download below. and A presentation at Hydra Connect 2016, described thus

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

This will be a half-day, hands-on workshop covering data modeling primarily in RDF. We hope to bring a diverse group of Hydra community members together to learn, discuss, and build out examples that will inform Hydra community best practices for data modeling. This modeling work will be taught in the context of helping Hydra and Fedora development, metadata, and interoperability efforts. We will discuss how model uses a number of standards, and demo the different ways to represent models. We will compare and contract data modeling with metadata standards/profiles. We will walk through modeling efforts around PCDM and its place in our work and community - this workshop will not focus on PCDM alone (this is not a PCDM or RDF workshop). We want this workshop to bring together, develop and engage a larger corps of data modelers in the Hydrasphere. and A workshop delivered at Hydra Connect 2016, described thus
