What’s New?

Metadata Task Group Update

The SHARE Metadata Task Group has made good progress towards formalizing the first metadata representation that will be used in SHARE Notify. The task group has proposed including two metadata collections with the schema to account for data that providers might have that is not necessarily in the set of well-defined, broadly usable, top-level fields of the schema. For example, if providers have metadata that conforms to another schema, they could include that data with a URI to the schema definition in a “structured properties” collection. A similar collection would support metadata that does not have a linked definition. This will allow the schema to accommodate many use cases for the SHARE data set—many of which may be currently unknown or be specific to particular niches (e.g., the inclusion of subject-specific schemas).

Technical Update

The SHARE development team continues to make improvements and develop exciting new features as we rapidly approach the release of the public beta in April. We have prototyped a registration system for future providers to register their service for inclusion in SHARE Notify either via a standardized format (e.g., OAI-PMH) or, ideally, a push-API endpoint for receiving pre-formatted data. We have increased code test coverage of the backend of SHARE Notify to 88% and established a more formal review, release, and quality assurance testing cycle. Data and requests are now stored in a Cassandra database to improve flexibility and scalability, and scripts for automatic deployment of the whole system are being created. A number of improvements have been made to the SHARE search and discovery space within the Open Science Framework (OSF), including the addition of interactivity to graphs and sorting options to search results.

What’s Next?

SHARE Community Meeting Scheduled for June 22–23 in DC

Members of the SHARE Joint Working Group, the development team at the Center for Open Science, and other invited guests will meet in person for a second time on June 22–23, 2015, in Washington, DC, at the Dupont Circle Hotel. A Program Committee Task Group will begin meeting in late March to design a balance of structured programs, “unconference” sessions, working meetings, and a hackathon to engage the developer community in working with the SHARE data set. Because the meeting is grant-funded, we regret that registration is by invitation only. However, we will live-tweet the sessions and make all meeting notes and materials available on the SHARE website.

SHARE to Present Project Briefing at CNI Spring Meeting in Seattle

At the Coalition for Networked Information (CNI) Membership Meeting in Seattle next month, Judy Ruttenberg of ARL and Jeff Spies of COS will present a session on SHARE Notify, which will be released in beta in April. Ruttenberg and Spies will demonstrate the service, describe plans for expansion of data providers through self-registration and push API, and discuss the focus on metadata enhancement in Phase II of SHARE. The SHARE project briefing will be held on Monday, April 13, at 4:00–5:00 p.m. PDT. Follow the meeting on Twitter with the hashtag #cni15s.

New SHARE Website Coming Soon

We are pleased to be putting the finishing touches on a new SHARE website. Designed by Color Crate with the input of a SHARE Website Design Task Group, the new site will go live in early April. We look forward to sharing more details in next month’s newsletter.

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 webinars presented in the fall and winter of 2014–15 by the SHARE team as part of the DuraSpace Hot Topics Webinar Series. The presentations cover the motivation behind SHARE, the progress of SHARE Notify, and SHARE’s future.
  • EDUCAUSE Review article on SHARE — Tyler Walters and Judy Ruttenberg describe SHARE’s first project, the SHARE Notification Service (now called SHARE Notify), 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 SHARE Notify 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.
