rOpenSci is a non-profit initiative founded in 2011 by Karthik Ram, Scott Chamberlain, and Carl Boettiger to make scientific data retrieval reproducible. Over the past seven years we have developed an ecosystem of open source tools, we run annual unconferences, and review community developed software.

rOpenSci fosters a culture that values open and reproducible research using shared data and reusable software.

We do this by:

  • Creating technical infrastructure in the form of carefully vetted, staff- and community-contributed R software tools that lower barriers to working with scientific data sources on the web
  • Creating social infrastructure through a welcoming and diverse community
  • Making the right data, tools and best practices more discoverable
  • Building capacity of software users and developers and fostering a sense of pride in their work
  • Promoting advocacy for a culture of data sharing and reusable software.

The Readium Foundation

The Readium Foundation is an Open Source Foundation collaboratively developing technology to accelerate the adoption of EPUB 3 and the Open Web Platform by the Digital Publishing Industry.

Readium Project Goals

The fundamental goal of the Readium project is to produce a set of robust, performant, spec-compliant reading system toolkits that support digital publishing formats (e.g. EPUB, Web Publications etc.) and can be deployed in browsers or built into native apps on iOS, Android or the desktop.

BitCurator Consortium

The BitCurator Consortium is an independent, community-led membership association that serves as the host and center of administrative, user and community support for the BitCurator environment. It is a continuation of the BitCurator Project (2011-2014) funded by the Mellon Foundation and led by the School of Information and Library Science (SILS) at the University of North Carolina, Chapel Hill and the Maryland Institute for Technology in the Humanities (MITH).

The BitCurator environment is a set of open-source tools adapted from the digital forensics industry for libraries, archives, and museum use. The tools extract digital objects, create metadata, ensure integrity, and identify sensitive data, providing libraries, archives, and museums with information to make appropriate processing decisions. The BitCurator environment is freely distributed under an open-source license. It can be installed as a Linux environment; run as a virtual machine on top of most contemporary operating systems; or run as individual software tools, packages, support scripts, and documentation.

Citation Style Language

Citation Style Language (CSL) is simply a very important project for publishing. It has widespread adoption in important platforms and plays a critical role in the scholarly publishing landscape. It is also important in that it is an open source project populated by a diverse set of skill sets and research perspectives.

The Citation Style Language project developed an XML-based format to define citation formats. Originally it was built to support the OpenOffice platform but has since been adopted on a wide scale.

The projects maintains a free and open source repository with currently over 9000 CSL citation styles for major style guides and individual journals (see and Dozens of software products, including popular reference managers such as Zotero, Mendeley, and Papers, have adopted CSL and its style library to give their users the ability to easily generate citations in a large variety of citation formats.


Recogito is a web-based environment for collaborative semantic annotation. It is open source software, and provides support for working with either text or image documents (including those served via IIIF, an open standard for publishing high-resolution imagery online). Originally, the tool has been designed with a focus on scholarly geographic annotation, i.e. the transcription, marking up and geo-resolving of maps and geographical texts, such as itineraries and travel reports, in the context of historical scholarship (e.g. to create maps from text, or to prepare a digital scholarly edition).

Over time and in response to how the tool was used and what researchers wanted Recogito’s feature set has grown continuously to: provide more general annotation functionality; widen the scope for other potential application areas; and allow for easy publication of research outputs online.

Recogito stands out for its ease of use, the unique way in which it enables novice users to perform a fairly complex and technical task – namely to create semantic markup on texts or images – without the need to deal with any of the technical aspects of semantic web technology and terminology.

Libero publishing suite

Libero publishing suite

Designed for academic publishing of the digital age, Libero is an open-source platform of services and tools available for hosted and self-hosted applications.

The Libero open-source platform helps scholarly publishers take a digital-first approach to everything we do. We’ve started with Libero Publisher, but there’s much more to come.

Atom Editor

Atom is a free and open-source text and source code editor for macOS, Linux, and Microsoft Windows with support for plug-ins written in Node.js, and embedded Git Control, developed by GitHub. Atom is a desktop application built using web technologies. Most of the extending packages have free software licenses and are community-built and maintained.
