Senior Advisor


Chuck has moved on from Crossref. Chuck Koscher joined Crossref in 2002. His primary responsibility had been the development and operation of Crossref’s core services and technical infrastructure. As a senior staff member, he also contributed to the definition of Crossref’s mission and the expansion of its services, such as the launch of the Open Funder Registry (formerly known as FundRef). His role included the management of technical support and back-end business operations. Chuck and his team interfaced directly with members in dealing with issues affected by new or evolving industry practices, such as those involving non-journal content like books, standards, and databases. Chuck had been active within the industry, having served 9 years on the NISO board of directors, and participated in initiatives such as the NISO/NFAIS Best Practice in Journal Publishing and NISO’s Supplemental Material Working Group. Prior to Crossref, Chuck had over 20 years of software engineering experience, primarily in the aerospace industry.

Preprints and Crossref’s metadata services

In Preprints

We’re putting the final touches on the changes that will allow preprint publishers to register their metadata with Crossref and assign DOIs. These changes support Crossref’s CitedBy linking between the preprint and other scholarly publications (journal articles, books, conference proceedings). Full preprint support will be released over the next few weeks.

A fairer approach to waiting for deposits

If you ever see me in the checkout line at some store do not ever get in the line I’m in. It is always the absolute slowest. Crossref’s metadata system has a sort of checkout line, when members send in their data they got processed essentially in a first come first served basis. It’s called the deposit queue. We had controls to prevent anyone from monopolizing the queue and ways to jump forward in the queue but our primary goal was to give everyone a fair shot at getting processed as soon as possible.

Crossref OpenURL resolver

In OpenURL

A new version of our OpenURL resolver was deployed July 2 which should handle higher traffic (e.g. we have re-enable the LibX plug-in ) Unfortunately there were a few hick ups with the new version which I believe are now corrected (a character encoding bug and a XML structure translation problem). Sorry for any inconvenience.

Crossref’s OpenURL query interface

Over the past two weeks we’ve focused on our OpenURL query interface with the goal being to improve its reliability. I’d like to mention some things we’ve done. We now require an OpenURL account to use this interface (see the registration page) . This account is still free, there are no fixed usage limits, and the terms of use have been greatly simplified. Resources have been re-arranged dedicating more horse-power to the OpenURL function.

On March 3rd the Open Archives Initiative held a roll out meeting of the first alpha release of the ORE specification ( . According to Herbert Van de Sompel a beta release is planned for late March / early April and a 1.0 release targeted for September. The presentations focused on the aggregation concepts behind ORE and described an ATOM based implementation. ORE is the second project from the OAI but unlike its sibling PMH it is not exclusively a repository technology.
