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'.]

A presentation given at the Open Repositories conference in 2015 held in Indianapolis described thus, provide an update on progress to date, At the University of Alberta Libraries we are currently developing a Digital Asset Management System (‘Hydra North’, built on Hydra and Fedora 4) to bring all of our digital assets into one platform for discovery, access and preservation. The metadata underlying these repositories has been created according to many standards (DC, MODS, EAD, etc.) and varies in level of fullness and overall quality. We find ourselves at a ‘metadata crossroads’ as we attempt to bring this disparate metadata together. We see a solution in a move to RDF and the application of the principles of linked data. In this presentation we will discuss some of the initial questions we asked ourselves as we tried to fully grasp what the move to RDF and linked data would mean for our existing metadata, provide concrete examples of the thought processes and workflows involved in moving from existing non-RDF metadata to RDF, based on the principles of linked data, outline some of the decisions we made along the way, and why, and what the impact has been, and reflect on lessons learned and outline next steps.

A presentation at Hydra Connect 2016 described thus and A follow-up to our presentation at Hydra Virtual Connect to show the progress we've made on Opaquenamespace.org. We'll discuss how we are using Git and github as our master-copy for RDF graphs, and using Blazegraph and the triplestore-adapter gem for our operational datastore.

//wiki.duraspace.org/display/hydra/Applied+Linked+Data+Working+Group, https, A workshop delivered at Hydra Connect 2016, described thus, and This workshop is all about techniques to use linked data within your Hydra based application. For example, autocomplete fields from a controlled vocabulary are nice... but what if you wanted to give more context to what users are selecting via things like alternative labels and broader / narrower concepts? How do you cache triples locally? How do do you publish your own controlled vocabulary for others to use? And what is the best way to make your RDF data harvestable by others? This workshop is based on work done by the Applied Linked Data working group

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
