ARK Alliance Newsletter, 2021, Volume 1, Issue 1

We are thrilled to announce the ARK Alliance. The ARK Alliance is the newly minted name for the global community that uses ARKs (Archival Resource Keys) as persistent identifiers in the scholarly ecosystem. That community was created by the very successful ARKs-in-the-Open project, begun in December 2018, as a collaboration between the California Digital Library (CDL) and LYRASIS/DuraSpace. With the foundation laid, the established initiative will go forward in partnership with LYRASIS as the ARK Alliance.

Growth, numbers, map

N2T ARK resolutions in 2019

The new brand

Besides the new name, we have a new website, arks.org. It’s early days so the site is still in the process of incorporating material held at the ARKsInTheOpen.org wiki and at the N2T.net resolver. Only ARK-specific information pages will move from N2T, which will carry on uninterrupted as the global ARK resolver.

The ARK Alliance Working Groups and Advisory Group will continue to be supported by the ARKsInTheOpen.org wiki.

There is also a new twitter handle: @arks_org. All followers of the former handle (@ARKsInTheOpen) are automatically already followers of the new handle. The old hashtag, #ARKsInTheOpen, is deprecated.

ARKs in the Open: 3.2 billion Persistent Identifiers

Bess Missell (Smithsonian Institution), Karen Hanson (Ithaka), Tom Creighton (FamilySearch International), and John Kunze (California Digital Library) gave a presentation last April at the CNI Spring 2020 virtual event where they shared the most recent developments on the ARK scheme, the AITO project as well as implementation experiences from each of their institutions. The presentation was recorded and is available at the following address: https://vimeo.com/412227303

INCIPIT - an ARK allocation service based in Switzerland

INCIPIT is a one-year project led by the Haute école de gestion de Genève which aims to develop a complementary infrastructure in Switzerland for the low-cost attribution of persistent identifiers to any concept or resource based on the ARK scheme. While having a Swiss scope, INCIPIT 2020 is involved in the AITO initiative as well as collaborating with the California Digital Library, notably on a shared software approach to mint identifiers.
