Stanford Digital Repository

For nearly four years, the Stanford Digital Repository (SDR) has been home to the research outputs of scientists and scholars from across Stanford’s campus. But while those data files, videos, source code, microscopy images, survey results, maps and more have been discoverable and accessible through the Libraries’ online catalog, SearchWorks, it has been hard to get an overview of all the available data. Until now.

The Stanford University Libraries (SUL) has introduced new features in its online catalog, SearchWorks, and the Stanford Digital Repository to make it easier for users worldwide to get access to a treasure trove of high resolution digital images.  The basis of these new features is the International Image Interoperability Framework, a global initiative co-founded by SUL to support the creation of a global network of broadly accessible images curated and produced by libraries, museums, archives and galleries to support research, teaching and broad public use.

The 2016 Summer Olympics are drawing lots of attention to Rio de Janeiro. But while most people are focused on the current games -- as well as current events, politics, and health issues that might impact the games -- others have been spending their time delving into the history of this more than 450 year-old city. And Stanford Libraries' own Claudia Engel couldn't resist dipping her hand in either.

In honor of the useR! 2016 Conference taking place this week, we wanted to outline ways researchers can use the Stanford Digital Repository to power their R visualizations.

The Stanford Digital Repository allow Stanford researchers and affiliates to deposit research data for preservation, access, and discovery. Data deposited in the repository is citable and from which the original content can be downloaded. The data is then made available through open web standard services for consumption. For example, images in the repository are delivered by a IIIF-compatible service, geospatial data are served out as Web Mapping Services (WMS) and Web Feature Services (WFS), and generic files are all served through HTTP.

R users can take advantage of these web services and the data being served out.

Water jet with x-ray pulse

When Stanford Digital Repository staff found out someone was depositing research data about using x-ray lasers to explode jets of liquid, I have to admit there was a bit of excitement. Researching explosions (even on a small scale) sounds like an immense amount of fun. But Stanford researcher Claudiu Stan and his colleagues were doing way more important things out at SLAC than just having fun. They were performing serious research into fluid dynamics.

About this series

Over the next few weeks I will post a series of brief step-by-step "how-to" tutorials on making use of digital resources from the David Rumsey Map Center and Collection, that I presented in my "Hacking Rumsey" talk, presented at the opening events for The David Rumsey Map Center, at Stanford University Library.

We're starting small, with the easiest tools (like the David Rumsey Map Collection MapTab Chrome Browser Plug-in, which I covered in a previous post) that appeal to the most people, first. Eventually we will work our way up through more complex use of the collections and tools available from The Stanford University Library.

Inquiry from a hot zone

In late March of 2016, Frederic Ham, a geospatial analyst for Medecins Sans Frontieres (MSF, also know as Doctors Without Borders) contacted Stanford University Libraries (SUL) looking for information. He needed data to help him create maps so that MSF could better plan their response to a current cholera outbreak in Zambia. He’d found what he wanted via SUL’s geospatial data portal, Earthworks, but wasn’t able to access it due to licensing restrictions. Was there any way we could help?

Rare Music Materials at Stanford is a Spotlight instance that presents materials from the Stanford University Libraries' collections that have been digitized in response to research requests, or were produced for small projects. Items and their downloadable images may also be found in SearchWorks, Stanford's library catalog.
