Nabeela Jaffer This is a suggestion, and will require multiple presenters
In-depth PCDM - what it is? what it does? how it works? how to implement? new developments? Managers, metadata people, developers, all ? Sheila Rabun per request Maybe someone who is presenting on PCDM at Open Repository?

This might or might not be part of the one above, but... PCDM for Dummies.

I think there is a need out there for a PCDM introduction that starts from a lower base from those I've so far seen. What are the community drivers for PCDM? (LDP, RDF, Fedora 4). Why? What does that give us? (solid examples of linked data being useful, and a nod to interoperability with non-Hydra folks). What does it mean for me? (for established users, moving from FOXML to a relationships graph) How do I do that? (Overview of data modelling with PCDM) How HyBox might help in this (standardisation, convergence) Etc, etc

New managers, established managers who still haven't got their heads around PCDM Short workshop Richard Green It might be a good learning experience for me to do it partnered with someone who knows PCDM and LDP/RDF well.
What Does It Mean to Be a Hydra Partner?
Discuss expectations, contributions and advantages of Partnership. Reinforce the distributed, participatory nature of the project.
All Panel, with audience interaction Tom Cramer panel of partners and perhaps 1 would be partner talking about Partnership.
Hydra Financial Vision & Organizational State (unless covered by a state of the HydraSphere or other high level preso). Review Hydra's financial status and Hydra Power Steering discussions around money. All Presentation followed by discussion Tom Cramer

Docker/Vagrant, what are they? creating, maintaining, using, etc. Developers Workshop Michael Friscia Colin Gross
Populating your repository with open source content from external systems - share experience or aspirations with methods, APIs, local features. More comment from Linda: I can speak as a project manager / dev team leader about my research trying to sort out the landscape with various platforms and APIs (some commercial / some open source) that offer potential for automatically discovering and perhaps ingesting content. This may relate well to the suggestion from Rick Johnson and Don Brower titled "Fedora Research Object Model and Hydra APIs." This could be a breakout session or panel (or even lightning talk) - I'm interested in hearing what experiences others have to share if they have tested using things like the Elsevier APIs (Scopus and Science Direct), the JISC Router, FigShare, Symplectic Elements, and/or the Open Science Framework, to even partially automate the discovery and ingest of open source content into your local hydra repository. I'm also interested if others have found ways to work with platforms such as and ResearchGate. All Panel followed by discussion newmanld Linda Newman + hopefully others with stories to share
Partner table or Q&A space possibly combined with Poster session - informal gathering opportunity for prospective partners with questions All social newmanld Idea from 6/10 partner call
Approaches to Asynchronous Storage and Hydra DevOps and Managers Panel Rick Johnson Idea from 6/10 partner call
Investigating a Hydra API to preservation systems (DuraCloud Vault, LOCKSS, Preservica, Arkivum, DPN, Tape, HSM, etc.) – (Related to Asynchronous Storage, above, but possibly distinct) Developers & managers Discussion / working group Tom Cramer May be a working or interest group meeting.
Introduction to Data Modeling (following discussions at LDCX on how to get more data modeling expertise in Hydra community) Current & would-be data modelers, people who want to know what’s the deal with data modeling Workshop Tom Cramer, Robert Sanderson possibly: tamsin woo, Robert Sanderson, matienzo, cmharlow
Technical On-Boarding - discussion of how to contribute code at the community level including such topics as: commonly used architecture patterns, expectations/suggestions for pull request size, determining the level of the gobstopper at which certain types of work should be implemented, etc. Developers who are planning/interested in participating in community-level dev efforts Workshop?

Testing with Rspec and Hydra

This will be a reprise of a workshop given at HC 2014, but improved and updated to cover new issues with the PCDM stack of gems, as well as strategies for test refactoring and speed improvement.

The workshop will go over testing practices for each of the principle unit components of an application (models, controllers, views, jobs, services, etc.) and also contrast that with how feature tests and written. Takeaways will include some "boilerplate" examples for each kinds of test, test suite configuration, continuous integration, and if time permits, one-on-one help with individual questions or blockers that anyone might be currently having.

Archiving Research Data into Hydra through the Open Science Framework (OSF) -

A look at initial work of Notre Dame and Johns Hopkins to archive research projects from the OSF into Fedora and Hydra repositories, and first implementation of a Fedora Research Object Model. This plugs into a service offering of the Center for for Open Science, OSF for Institutions (OSF4I). ND/JHU version will be initial support for OSF Fedora Archiving Add-on in the OSF as part of OSF4I offering. We hope to start discussion around next steps for other Hydra institutions to use this along with OSF4I to allow them support to archive research data from the OSF into their own Hydra/Fedora repository.

Fedora Research Object Model and Hydra APIs-

Based on initial work by Notre Dame and Johns Hopkins for archiving an OSF project into a Fedora repository, start community discussion around developing standard data model(s) (i.e. ontologies) for a Research Data Object coming into Fedora and Hydra. This relates to some discussions around HyBox and standard APIs into Hydra. Can we develop standard models for Research Data Packages (i.e. objects) that are sent and received through standard Hydra interfaces? In turn, can these APIs be used to send and transmit information between Hydra and external systems like the OSF, Figshare, CRIS systems, profile systems, etc? We look to use ND/JHU work as reference implementation and foster this effort towards community models that would then be adopted and nurtured community-wide.

Hydra, research data and Archivematica

Notwithstanding Rick's ideas above, a couple of us in the UK are looking at Archivematica's place in a research data pipeline. Hull and York have slightly different use cases but share the desire to put research (and likely other) content through Archivematica on its way to the repository thus giving us a solid base for long-term preservation. At the time of writing (June) we are each building a proof-of-concept system and this work should be complete and demonstrable by October.

Moving Features to the Core

I'd like to have a discussion/working session with folks who have built Sufia- or CurationConcerns-based applications to learn about what features they've been adding, and to discuss ways to move these features from the edges into the core for broader impact and long-term maintenance. One area of focus will be hearing from the folks at University of Virginia about the features they've built in their Sufia 7-based Libra 2 application. The goal is to leave the session with a lightweight plan and timeline for extracting features into community-maintained components.

Hydra in a Box

An update on recent progress on the Hydra in a Box project, including work related to product development for the repository and metadata aggregation components, development of the hosted service, development and infrastructural decisions, and community engagement. (We're willing to take some feedback from the Program Committee about how to best shape our presentation.)

Profiling your Stack - Everything's Slow, What Now?

The Hydra stack is large and complex, getting a handle on what's causing a specific slowdown can be difficult. This session would recommend some tools, strategies, and places to look for improving the performance of your application.

Standard APIs and Interfaces for Interoperability

We've settled on standard solutions like LDP and PCDM within our community, but what does it get us? This session would focus on the current and potential benefits of the standards we've fallen down on, as well as identify opportunities for further interfaces and collaboration with institutions who may not be using Hydra.

Intro to Elixir

Some of us in the Hydra community have been looking at other tools to supplement our Hydra stacks. This would be a workshop to introduce a fast new language with ruby-like syntax, concurrent processing, and a stable framework.

Efficient development and deployment of Hydra projects using Vagrant.

In this presentation, we will present a software development and deployment process that we have developed at Virginia Tech. We have used this procedure to develop several Hydra projects for University Libraries services at Virginia Tech and have also used it to conduct interviews for Ruby and Rails developers. We implemented a central vagrant box to facilitate the development and deployment processes. Using this vagrant box gives us many benefits: 1. Code immediately. Our software engineers can focus on coding without worrying about software installation. 2. Unified development environment. All developers do their work in the same, consistent development environment. 3. Development of multiple projects simultaneously. Developers can work on multiple projects in parallel, switching between project environments in just a few minutes. 4. Minimal differences between development environments and production environment. After we finish implementation, we can quickly deploy our applications into a cloud environment (e.g. AWS and OpenStack) that is highly consistent with our development environments. We will present and demonstrate our hands-on experience on how we use a single vagrant box with different GitHub repositories to develop multiple Hydra applications in detail, including Sufia, GeoBlacklight, Fedora, Solr, Vagrant, AWS, and OpenStack.

Managing Developers

I'm thinking of a session where managers can meet to discuss approaches to adopting agile methodologies, balancing Hydra with non-Hydra project needs, inspiring staff, training, recruiting techniques, etc. I imagine this session may happen when a lot of developer focused sessions are taking place and managers may feel out of place and could be an interesting place for managers to share their leadership styles/practices.

Update from the Architecture Working Group

We don't know our outcomes yet, but since the group was capped at 10, it feels important that we report our progress to the wider community, as the "Gobstobber" stack continues to evolve.

Google Scholar Optimization

UAlberta has been struggling with getting our content indexed in Google Scholar since we moved to Sufia. However, inclusion in Scholar is absolutely critical to recruitment of content for our repository. We would love to have a discussion with others about how to improve Google Scholar indexing for Hydra repos - we can share strategies we've adopted, and would love to hear more about how others are solving this issue at their institution.

Towards Easing the Maintenance of Hydra-based Solutions:
The Hydra-in-a-Box project team has been considering what it means to offer a Hydra product that is "easy to maintain". We can envision several scenarios that reflect differing degrees of maintainability. We wish to engage the community in a conversation that explores these scenarios and how the community can evolve and organize itself to advance the maintainability of our products, in the interest of increasing Hydra adoption and sustaining Hydra long-term, without curtailing the dynamic, vibrant nature of our codebase.

Scoping & Managing Your Hydra Project

As a manager, one of the biggest challenges when starting any project (Hydra, or otherwise) is feeling comfortable that you’ve asked all the right questions before the first development hour is logged. But what are the right questions? And once you begin, how do you ensure that you, your developers and your stakeholders remain on the same page throughout the course of the engagement? This presentation will explore two processes that DCE employs to tackle these concerns. We’ll examine how a scoping phase consisting of a series of meetings carefully crafted to squash ambiguity and get to the nitty-gritty of your project’s needs can help start a traditional or agile project off with less uncertainty. We’ll also discuss how an Inception Deck can work to consolidate project expectations and fend-off wild assumptions, helping you to feel confident that when everyone says ‘circle,’ no one’s nodding and picturing a square.

The Hydra-Stack / PCDM Live Walkghrough

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: 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: 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?

Either a 45 minute demo/presentation OR a 2 hour hands-on workshop with attendees following along at each step.
