Stanford Medicine CEDAR: Better Data for Better Science

Advanced UX, UI and Angular JS

The Brief

The Center for Expanded Data Annotation and Retrieval (CEDAR) is a collaboration between Stanford Medicine, University of Oxford, Northrop Grumman, and Yale University. They have developed information technologies that make authoring complete metadata much more manageable, and that facilitate using the metadata in further scientific and medical research. The project goal is to help investigators achieve the promise of Big Data. To do this, we built a system that uses computers to make life better for biomedical researchers providing and using metadata. People can now use the CEDAR tools to create or search templates or metadata for their research.

MJD worked with Stanford providing strategy, user experience research and documentation, user interface design and testing, and an innovative Symfony/Angular headless technology framework.

Strategies

We believe ease of use is paramount. Because the ability to share data is so important, we wanted the process of metadata creation and use to be as painless as possible. Our strategic approach addressed the challenges we have seen in other similar projects.

Six key elements contribute to what we believe will be a successful system:

  • Interfaces and tools built and tested specifically for metadata creation
  • Consistency in terminology
  • Machine learning
  • Editing capabilities
  • Training and outreach
  • Building on past work and leveraging ongoing collaborations

Extensive prototyping and testing was undertaken to ensure that the six key elements were successful.

Building the Platform

After the UX/UI prototypes were built and tested, we began to build the system. We created a custom content management and data repository system using Symfony and Angular. We designed and built an API that allowed metadata to flow into and out from the system, making it easy for researchers to create forms for research studies that are inherently tagged with data readable by anyone around the world in a consistent way.

Results

  • The world’s first consistent terminology tool for medical research metadata
  • Utilization of machine learning to analyze Big Data to make research data available worldwide in real time
  • Better data means better science

“The MJD team provided software development implementing CEDAR’s interactive web services for template creation and metadata instantiation. MJD developer Aaron Straker masterfully integrated our early concepts and notional wireframes, and the MJD team continued to support the beginnings of the CEDAR web service platform.”

“Most important to the successful CEDAR launch was MJD’s ability to integrate key usability concerns, like responsive interfaces, thoughtful layout and functional analysis, engineering for mobile applications, and solid application of user interface development principles. We finished our first year in strong development shape thanks to the MJD investment.”

Meaningful Connections

At MJD we are striving to give meaning to the digital connections between people. We aim to elicit emotion when someone uses a digital product, experience or platform that we’ve designed and built. It could be something simple like a beautifully designed user interface that makes working with a smartphone exceptionally easy. It could be something hard like creating a Store of the Future where little girls can fall in love with a doll and be inspired to create their own strong path in this big world.

Digital Innovation Agency

Digital innovation is disrupting entire industries, transforming consumer behavior and influencing the way people interact with brands and products. In our 24/7 world, companies are leveraging digital technologies to create tremendous value, efficiencies and new revenue models while their customers expect ever more personalized and engaging experiences.
