SHARE Update, January 2015

What’s New?


SHARE presented an update on our progress at the Coalition for Networked Information (CNI) Fall 2014 Membership Meeting in Washington, DC. Tyler Walters (dean of university libraries at Virginia Tech and SHARE director), Eric Celeste (SHARE technical director), and Jeff Spies (co-founder of the Center for Open Science), described SHARE’s 2014 progress and in particular the work that has been done on the Notification Service prototype. Our project briefing was to a full room and the presentation slides are available on the CNI website. One aspect of SHARE that prompted discussion at this briefing was the open nature of SHARE data. We described some of the challenges to acquiring data that we could freely share with others, which prompted some concern that our data would be available for commercial exploitation. We reiterated that our intention is that SHARE data be open to all, whether their interest is academic or commercial.

During the weeks leading up to CNI our conception of what we had been calling the “SHARE Registry” had also been evolving into a notion of a set of SHARE records first populated by the Notification Service, but then enhanced in place. We shared this “Phase II” concept in our project briefing at CNI and then held an all-day meeting after CNI—which included representatives from DuraSpace, bepress, OpenAIRE, the Center for Open Science, and others—through which we gathered useful feedback on this Phase II idea. Among other suggestions, participants pushed SHARE to consider the nurturing of a community around SHARE at least as carefully as we nurture the technology. We anticipate opportunities for “SHARE-Enabling” institutions during the coming year as part of this community-building effort.

Technical Update

The Center for Open Science has been focusing on making improvements to the usability and documentation of the SHARE Notification Service, while preparing for new ways for providers to include their data. We have developed prototypes for users to push their pre-normalized data straight to an API route, or register and normalize their own OAI-PMH-formatted data stream. We have also made it easier for content providers to see how the normalized version of their data coming through the Notification Service compares with the raw record that was originally harvested. We are also starting to develop use cases of the Notification Service by building a few example apps that interact with the API and display results.

What’s Next?

Setting the Stage for SHARE’s 2015

SHARE had a very productive 2014. We secured funding, forged a development partnership with the Center for Open Science, built a working prototype of the SHARE Notification Service, and developed a community of stakeholders encompassing repositories, libraries, university administration, funding bodies, publishers, and technology organizations.

In 2015, SHARE will be proceeding along two closely related paths. First, we will continue to develop and roll out the Notification Service. In the spring, we will officially enter beta, with a broader range of data providers and consumers beginning to test the system. The beta will continue to expand over the course of the summer, with an eye toward the first full release of the SHARE Notification Service in the fall.

Concurrently, the SHARE team will be planning for our Phase II development. As alluded to in the “SHARE at CNI” section above, we are in the process of drafting a project plan to describe how SHARE will deepen and enhance the records created by Notification Service events. For example, the Notification Service will process reports of preprints by two co-authors from their respective institutional repositories as two distinct events, the publishing of their final article as another event, and the posting of their data set in an NCBI data repository as yet another event. In Phase II of SHARE we plan to account for the relationships among these events by associating these activities with one another. We also plan to work closely with a set of pilot SHARE-Enabling institutions to determine the changes in workflow and data practices required to make this possible.

Our expectation is that a draft project plan will be available to our working group by late winter, funding will be secured by this summer, and development will commence immediately thereafter.

Learn More

As always, there is a wealth of resources at your disposal to help you better comprehend and communicate the ins and outs of SHARE, including:

  • SHARE Knowledge Base — provides short, non-technical answers to key SHARE questions ranging from “Who is behind SHARE?” to “What is SHARE doing about data?” If you or someone on your campus has a practical or conceptual question about SHARE, the Knowledge Base is likely to have your answer.
  • SHARE Webinars — recordings and slides of three recent webinars presented by the SHARE team as part of the DuraSpace Hot Topics Webinar Series. The presentations cover the motivation behind SHARE, the Notification Service’s progress to date, and SHARE’s future.
  • EDUCAUSE Review article on SHARE — Tyler Walters and Judy Ruttenberg describe SHARE’s first project, the SHARE Notification Service, as well as the other three layers of SHARE that will be developed in tandem with the Notification Service: a distributed content and registry layer, a discovery layer, and a content-aggregation layer that moves beyond curation and discovery to facilitate data and text mining.
  • SHARE Notification Service Project Plan (PDF) — details the first in a series of activities to be undertaken by SHARE to ensure that scholarly research outputs are discovered and built upon in a manner that facilitates and accelerates the research process.
  • SHARE on GitHub — Technical developments pertaining to the SHARE Notification Service are discussed and tracked in real time via GitHub. The SHARE GitHub site includes a list of active notification sources and consumers, as well as information regarding prototypes, APIs, and other key issues. The site is open and welcomes public input.
  • Supporting Organizations — SHARE is a higher education and research community initiative to ensure the preservation of, access to, and reuse of research outputs. We are pleased that a wide array of stakeholders endorse these goals. If you would like to add your organization to this list, please e-mail


The SHARE Notification Service is being developed with the generous support of the Institute of Museum and Library Services (IMLS) and the Alfred P. Sloan Foundation.
