Maryland, Virginia, Washington D.C, etc.

We want to bring the code{4}lib experience to the library community in the Maryland, Washington, D.C., and the great Commonwealth of Virginia area. Our hope is that meeting at the regional level will strengthen our local connections and develop more real world collaborative efforts.

We met quarterly throughout 2012, and continuing through 2014 and 2015. We've enjoyed a number of in depth technical presentations on a variety of topics. Meetings have been free to attend. Past host institutions have been the Smithsonian, GWU, and the Arlington Public Library. If you are in the area, please do feel free to drop in. If you are unable to make it in person, check with the hosts to see if distance participation is an option. We did have one distance person with us at one of the Smithsonian meet ups. :)

Next Meeting

All registration, planning, and logistical information has been moved to the C4L MDC 2015 Meetup Page.

Last Meeting

Code4Lib DC 2014 unconference

August 11-12, 2014
Gelman Library
George Washington University

Connect with fellow code-interested cultural heritage professionals at two side-by-side events: a DC-area code4lib unconference and an introduction to programming workshop. As typical of unconferences, the content and activities of the day are determined by the attendees. Bring your ideas! We encourage everyone to consider giving a 10-20 minute talk, a lightning talk, lead a workshop, or organize another activity.

The two events are intended to provide an inclusive, welcoming environment, supported by the DLF Code of Conduct. The schedule includes opportunities for the attendees in each track to meet each other, including a plenary opening session, shared lightning talks, Day 2 afternoon unconference events, and combined coffee/lunch/snack breaks.

These events are sponsored by the Digital Library Federation and the GW Libraries.

Details, schedule, and registration: GW Libraries site.

20-minute talks - feel free to sign up

  • Dan Chudnov (GW Libraries), "7±2 things code4libbers should know about data science"
  • Mark Matienzo (Digital Public Library of America): "What We Learned From Aggregating Metadata for 7 Million Items"
  • Bohyun Kim (UMB HS/HSL), "Accepting Online Payment for Your Library and 'Stripe' as an Example"
  • Francis Kayiwa, "Monitoring Sucks"
  • David Anderson (National Library of Medicine): "Linked Data at NLM"
  • Ben Wallberg (UMD Libraries), "Research Services at UMD Libraries"
  • Ruth Kitchin Tillman (EADiva, NASA Goddard), "EAD 2002 to EAD3: the N big changes"

5-minute lightning talks signups - on site

  • see whiteboard in room 302

1.5 or 3 hour workshops - feel free to sign up

Practice jQuery, for those in workshop (1.5 or 3 hours)

Jason Griffey, Hacking on Hardware (3 hours):

Come and join me for an afternoon filled with circuits and silicon! We'll be learning the basics of breadboards and simple circuits, and will deconstruct and then rebuild our own input/output systems with Arduino. Learn the basics of programming to the Arduino...hardware will be provided, although you will need your own laptop (or are comfortable team learning with someone else). The goal of the workshop will be to give you enough knowledge that you can build a simple sensor to measure something in your environment (noise, temperature, light, moisture) and to make you more comfortable with working with hardware. This session is designed for beginners who do not have experience with circuits, breadboards, Arduino, or other aspects of hardware hacking.

If you are planning to attend this hardware hacking afternoon, you will need to install a couple of things before you arrive to save time. Please download and install both the Arduino IDE 1.0.5 and the FTDI Drivers (serial drives for the Sparkfun Redboard), linked below. These will allow your laptop to communicate with the board.

Arduino IDE

FTDI Drivers

Kevin Ford, Gettting Started with the Bibframe Editor (1.5 hours):

Learn about, download, locally install, and tinker with the nascent Bibframe Editor (bfe) ( This workshop will provide an introduction to the Bibframe Editor, which, despite its name, is basically a generic, web-based RDF editor. All forms are dynamically generated from specially defined JSON-formatted Bibframe Profiles, which you can customize with your own classes and properties to meet your needs. `bfe` also ships with a number of "look ups," which provide typeahead functionality that dynamically search remote value vocabularies, such as Names and Subjects in ID.LOC.GOV, and allow you to choose a value from a suggested set of values (you can also create your own look ups). After a brief introduction about `bfe`, we'll work to install it on your own laptop. We'll then learn a little about profiles by modifying a few existing ones. Time permitting, we'll look at creating a new "look up."

Preparing ahead of time?

Essential: node.js OR Python 2.7 (Do please try to have these installed before the workshop, otherwise we'll spend a minute or two installing node.js.)

Optional: Git

Patrick Murray-John, Omeka under the hood (1.5 hours)

September 13, 2011

Tuesday, 13 September, 2011 10-11.20ish at Arlington Public Library Central Branch in Arlington, VA

With representatives present from Public, Academic, and Special Libraries, this looked to be a great start to rejuvenating the Chapter. (School Librarians, come out and play!) We had a great discussion about Linked Data. We reaffirmed that we'll hold quarterly meetings, and that doing so regularly will help keep things rolling. We hope to have diverse subjects to explore to keep everyone's interest. We'll hold off on formal governance until a larger group necessitates formality.

The Martin Luther King Library in the District would like help with Library Lab DC if anyone would like to participate in that endeavour. This is also a wonderful place to go if you're looking for spot to house open collaboration.

There were a couple of interesting meetings and events to attend that we shared with one another.


  • 10 - Noon Main Meeting
  • Introductions
  • Discussion of current venue.
  • Shameless plug for ( Fall for the Book)
  • Hash out possibilities of other venues.
  • Is the frequency right? Will quarterly meetings still work?
  • Is the Chapter's problem indicative of fragmented general regional Library collaboration?
  • Update on the wider code{4}lib community
  • Discuss and invite folks to get involved with Library Lab DC at the DCPL
  • Requests, ideas, and volunteers for topics for future gatherings
  • Governance (do we want any?)
