The Avalon Media System: A Next Generation Hydra Head For Audio and Video Delivery

The Avalon Media System: A Next Generation Hydra Head For Audio and Video Delivery

Slide presentation

  • Michael Klein, Senior Software Developer, Northwestern University LIbrary, michael.klein AT northwestern DOT edu
  • Nathan Rogers, Programmer/Analyst, Indiana University, rogersna AT indiana DOT edu

Based on the success of the Variations digital music platform, Indiana University and Northwestern University have developed a next generation educational tool for delivering multimedia resources to the classroom. The Avalon Media System (formerly Variations on Video) supports the ingest, media processing, management, and access-controlled delivery of library-managed video and audio collections. To do so, the system draws on several existing, mature, open source technologies:

  • The ingest, search, and discovery functionality of the Hydra framework
  • The powerful multimedia workflow management features of Opencast Matterhorn
  • The flexible Engage audio/video player
  • The streaming capabilities of both Red5 Media Server (open source) and Adobe Flash Media Server (proprietary)

Extensive customization options are built into the framework for tailoring the application to the needs of a specific institution.

Our goal is to create an open platform that can be used by other institutions to serve the needs of the academic community. Release 1 is planned for a late February launch with future versions released every couple of months following.

EAD without XSLT: A Practical New Approach to Web-Based Finding Aids

EAD without XSLT: A Practical New Approach to Web-Based Finding Aids

Slide presentation

  • Trevor Thornton, New York Public Library, trevorthornton@nypl.org

The New York Public Library is reengineering its system for delivering archival finding aids on the Web. The foundation of this system is a data management application, written in Rails, within which collections and their components are managed as associated model instances, and descriptive data is stored natively as JSON and HTML. Front-end applications interact with the back-end via a flexible API that is capable of returning any part of the description at any level. This approach provides a number of benefits over the traditional XML/XSLT approach:

  • Data is stored natively in the format in which it is needed by the front-end application, making rendering much faster
  • Finding aid data can be lazy-loaded via AJAX requests
  • Enables presentation of the archival description beyond the traditional finding aid structure (alternate arrangements, visualizations, etc.)
  • Links to digital assets can be maintained independently of archival description
  • Data cleanup and normalization can be accomplished during and/or after ingest of original data into the system, ensuring data quality and consistency
  • Data is stored in a schema-neutral format, enabling easy transformation into other formats as required (e.g. RDF for semantic web applications, future version(s) of EAD schema for harvesting, etc.)

In this session I will describe the architecture of this system and its data model, and discuss the challenges presented in the design process.

Hacking the DPLA

Hacking the DPLA

Slide presentation

  • Nate Hill, Chattanooga Public Library, nathanielhill AT gmail.com
  • Sam Klein, Wikipedia, metasj AT gmail.com

The Digital Public Library of America is a growing open-source platform to support digital libraries and archives of all kinds. DPLA-alpha is available for testing, with data from six initial Hubs. New APIs and data feeds are in development, with the next release scheduled for April.

Come learn what we are doing, how to contribute or hack the DPLA roadmap, and how you (or your favorite institution) can draw from and publish through it. Larger institutions can join as a (content or service) hub, helping to aggregate and share metadata and services from across their {region, field, archive-type}. We will discuss current challenges and possibilities (UI and API suggestions wanted!), apps being built on the platform, and related digitization efforts.

DPLA has a transparent community and planning process; new participants are always welcome. Half the time will be for suggestions and discussion. Please bring proposals, problems, partnerships and possible paradoxes to discuss.

Pitfall! Working with Legacy Born Digital Materials in Special Collections

Pitfall! Working with Legacy Born Digital Materials in Special Collections

Slide presentation

  • Donald Mennerich, The New York Public Library, don.mennerich AT gmail.com
  • Mark A. Matienzo, Yale University Library, mark AT matienzo.org

Archives and special collections are being faced with a growing abundance of born digital material, as well as an abundance of many promising tools for managing them. However, one must consider the potential problems that can arise when approaching a collection containing legacy materials (from roughly the pre-internet era). Many of the tried and true, "best of breed" tools for digital preservation don't always work as they do for more recent materials, requiring a fair amount of ingenuity and use of "word of mouth tradecraft and knowledge exchanged through serendipitous contacts, backchannel conversations, and beer" (Kirschenbaum, "Breaking badflag").

Our presentation will focus on some of the strange problems encountered and creative solutions devised by two digital archivists in the course of preserving, processing, and providing access to collections at their institutions. We'll be placing particular particular emphasis of the pitfalls and crocodiles we've learned to swing over safely, while collecting treasure in the process. We'll address working with CP/M disks in collections of authors' papers, reconstructing a multipart hard drive backup spread across floppy disks, and more.

ARCHITECTING ScholarSphere: How We Built a Repository App That Doesn't Feel Like Yet Another Janky Old Repository App

ARCHITECTING ScholarSphere: How We Built a Repository App That Doesn't Feel Like Yet Another Janky Old Repository App

Slide presentation

  • Dan Coughlin, Penn State University, danny@psu.edu
  • Mike Giarlo, Penn State University, michael@psu.edu

ScholarSphere is a web application that allows the Penn State research community to deposit, share, and manage its scholarly works. It is also, as some of our users and our peers have observed, a repository app that feels much more like Google Docs or GitHub than earlier-generation repository applications. ScholarSphere is built upon the Hydra framework (Fedora Commons, Solr, Blacklight, Ruby on Rails), MySQL, Redis, Resque, FITS, ImageMagick, jQuery, Bootstrap, and FontAwesome. We'll talk about techniques we used to:

  • eliminate Fedora-isms in the application
  • model and expose RDF metadata in ways that users find unobtrusive
  • manage permissions via a UI widget that doesn't stab you in the face
  • harvest and connect controlled vocabularies (such as LCSH) to forms
  • make URIs cool
  • keep the app snappy without venturing into the architectural labyrinth of YAGNI
  • build and queue background jobs
  • expose social features and populate activity streams
  • tie checksum verification, characterization, and version control to the UI
  • let users upload and edit multiple files at once

The application will be demonstrated; code will be shown; and we solemnly commit to showing ABSOLUTELY NO XML.

Getting Around

CTA

Locals prefer the Chicago Transit Authority. You can pay in cash, but it's much easier (and a bit cheaper*) to purchase a transit card. You can buy one at the airport, the Dominick's Grocery Store 1/2 block north of the hotel on Halsted Street, or at any train station.

Get bus and train arrival time information from the CTA mobile site.

If you don't have a transit card, a cash trip will cost you $2.25. Exact change is required.

*As of last month, it now costs $5 to travel to and from O'Hare airport via the train. Hello, tourist tax!

Taxis

Reasonably-priced for short trips around the Loop, but if you're going to the airport, the CTA is the more reliable (traffic-wise) and cheaper option.

Call or book online:

Walking

If you're staying at the Crowne Plaza and fancy a walk, it will take you about 25 minutes. The stretch of Halsted Street south of the hotel goes through the heart of Chicago's lively Greektown neighborhood.

Standard safety procedures apply: be aware of your surroundings, don't walk alone at night or if you're uncomfortable, etc.
