PKP and Crossref are collaborating to help publishers and journals using Open Journal Systems (OJS) take better advantage of Crossref services. As of 2014, PKP has become a Sponsoring Organization of Crossref, and as such will be providing much improved Crossref integration and overall support for the service. Additionally, PKP can now act as a sponsor representative for OJS journals wishing to apply for Crossref membership, and is in some cases able to waive fees.
PKP is working with Crossref to improve the level of overall DOI export support provided within OJS. OJS has included a basic manual export plugin for several years; this plugin will be extended in the following ways, and will be freely available to any journal using OJS (2.4.5+).
The Crossref Export/Registration plugin is still undergoing active development. We intend to focus on the following enhancements from OJS 2.4.8 and, particularly, into the OJS 3.0 release.
