New IDF General Member
The IDF welcomed Korea Institute of Science and Technology Information (KISTI) as a new General Member of the IDF in August 2015. KISTI is a government-funded research institute that supports high-tech R&D for researchers by collecting science and technology information from countries around the world and providing the information to companies and research institutions.
The DOI Twenty Years On
D-Lib Magazine published "The DOI Twenty Years On" in the July/August 2015 issue, a transcript of a talk given by Mark Bide at a recently held International DOI Foundation meeting. The meeting celebrated the 20th anniversary of "The Armati Report", which was instrumental in the creation of the Digital Object Identifier. See http://doi.org/10.1045/july2015-bide.
Analysis of January 2015 DOI Domain Name Outage
The doi.org domain name was inadvertently allowed to expire for a brief period on the morning of 20 January. It was reinstated shortly before 9 a.m. EST as soon as Corporation for National Research Initiatives (CNRI) learned of it. A note was sent to all Registration Agencies (RAs) at 3 a.m. UK time explaining the issue, and a notice placed on the website later that day (it remained in place until recently). The outage was due to a domain name administration error following a change of registrar (which was necessary in order to incorporate DNS SEC improvements). We sincerely apologize for any difficulties this may have caused to our users. Steps have now been taken to prevent any repeat of this event.
A post event analysis of the problem was then circulated to all RAs on 29 January. After collecting and comparing logs for the two weeks prior to and following the outage, a further detailed analysis of the effect of this outage was completed on 13 February, and showed that DOI resolutions fell between 7 a.m. and 8:30 a.m. to between 1/3 and 1/2 of typical; traffic was still less than typical until about 9 a.m. the next day, as Internet caches were re-populated with correct data. The RA most affected appears to have been CrossRef (no other RAs reported problems) who have performed their own analysis; CNRI will be providing a response to that analysis.
This was the first major connectivity problem we have encountered with DOI in over 15 years of operations; in fact the outage was not due to the underlying Handle System but a relatively simple clerical error with the domain name, and the Handle System remained fully operational throughout; however users resolving through the doi.org proxy using http were unable to resolve DOIs for a short period (the handle.net proxy remained operational). No DOI records were of course compromised or lost in this period. The issue was highly regrettable but has been addressed.
One point to note is the difference between uptime and persistence in the long term (ensured through social as well as technical agreements). Both should be 100%, but there is no direct link between not being able to resolve a DOI on dx.doi.org at any given point in time, and whether that DOI will still be meaningfully resolvable 100 years from now: both matter, but they are different issues. We are examining continuing improvements to our persistence infrastructure (through, e.g. the DONA Foundation), functionality, and our interoperability principles (through, e.g. the Linked Content Coalition partnership).
We remain committed to running the most successful persistent and interoperable identifier system and are examining what other lessons may be learned from the event for continuity planning.
DOI Outreach Meeting 2014, 21 November 2014, Milan, Italy
The 2014 DOI Outreach Meeting, organised by DOI Registration Agency mEDRA, focused on services enabled by DOIs demonstrated by use cases showing applications and external projects within the DOI community. A collection of presentations from the meeting is available here. See also "DOI unveiled", a Smart Book Report on Outreach Meeting 2014 by Paola Mazzucchi, AIE - mEDRA
DOI System reaches 100 million registrations
The 100 millionth DOI has now been assigned, via the Entertainment Identifier Registry, a DOI-based registry of universal unique identifiers for movie and television assets. This significant milestone builds on earlier growth. The ten millionth DOI was assigned in August 2003 via another major Registration Agency, CrossRef, as a persistent, interoperable, and extensible identifier to a technical article in a journal; and the millionth DOI was assigned in April 2000. DOIs are assigned by a growing federation of Registration Agencies across a variety of content sectors and language areas, and are in use by over 12,000 registrants. For further information, see DOI Registration Agencies & Entertainment Identifier Registry.
International DOI Foundation participates in new Linked Content Coalition
The International DOI Foundation is pleased to be one of the six founder Board members of the LCC. A further group of standards bodies, including many of the International Agencies for the ISO TC46/SC9 Information and Documentation identifier standards, are now set to join. The Linked Content Coalition (LCC) is a not-for-profit global consortium of standards bodies and registries with a remit to facilitate and expand the legitimate use of content in the digital network. Its Ten Targets for a Digital Future aim to ensure that every creator and every creation can be automatically identified on the Internet if they wish to be; that every creation can have machine-readable rights information linked to it (whether for commercial or free use); and that existing standards of different media types can be interoperable. Download the full press release from LCC more information.
Facilitating the use of DOIs in Wikipedia
Wikipedia is the 8th largest referrer of DOI links to published research, despite only a fraction of eligible references in the free encyclopaedia using DOIs. CrossRef, a DOI Registration Agency, is joining with Wikimedia in launching a new initiative to better integrate scholarly literature in the world's largest public knowledge space, Wikipedia. This work will help promote standard links to scholarly references within Wikipedia, which persist over time by ensuring consistent use of DOIs and other citation identifiers in Wikipedia references. See the CrossTech posting to learn more.
DOI Outreach Meetings
DOI outreach meetings were held in Asia in December 2013, on December 4 in Taipei and December 6 in Beijing. These were one day meetings were organised by local DOI Registration Agencies (Airiti, Inc. in Taipei; The Institute of Scientific and Technical Information of China (ISTIC) and China National Knowledge Infrastructure (CNKI) in Beijing). The meeting theme was "Open Meeting: Innovative Content Applications Driven by DOI". Each meeting gave an overview of DOI and its underlying principles, followed by presentations from several RAs (CrossRef, DataCite, and EIDR) describing how they have implemented DOI for their industries and giving examples of the applications that have been built. Presentations from the outreach meetings are available here.

DOI System reaches one billion resolutions per year
The DOI system reached a significant point in its development during 2012, with DOI resolution growing to a rate of one billion DOI resolutions per year. 2012 also saw the publication of the DOI system as international standard ISO 26324 and the appointment of additional Registration Agencies. Note that by late 2014, DOI resolution had grown to a rate of 1.2 billion DOI resolutions per year.
The International DOI Foundation is pleased to announce the appointment of a further Registration Agency in China. China National Knowledge Infrastructure (CNKI), launched in 1988, is the largest authoritative, comprehensive source of China-based information resources in the world, reflecting the latest developments in Chinese politics, economics, humanity and social science, science and technology. The parent company of CNKI is Beijing-based Tsinghua Tongfang Knowledge Network Technology Company (TTKN), founded by Tsinghua University. CNKI publishes databases containing e-journals, newspapers, dissertations, proceedings, yearbooks, reference works, etc. CNKI is the second agency to be appointed in China, with ISTIC already a major agency in the DOI community. The appointment of a second DOI agency in China reflects the importance of the digital sector in one of the world's largest economies.
DOI system strengthens social infrastructure
DOI Registration Agencies are free to offer to their customers unique services built on DOI registration. The DOI system has now agreed an additional Registration Agency Collaboration Policy, which provides safeguards ensuring that customers can choose from multiple Registration Agencies for appropriate services whilst avoiding the allocation of multiple DOI names to the same entity, or conflicting services for one DOI name. The policy also sets out appropriate measures for sharing information across DOI Registration Agencies within the DOI federation. The policy joins other existing policies which form a social infrastructure unique to the DOI system, which ensures persistence and interoperability. For further information see the DOI Handbook, 6 Policies.
