eLife recently won a Crossref Metadata Award for the completeness of its metadata, showing itself as the clear leader among our medium-sized members. In this post, the eLife team answers our questions about how and why they produce such high-quality open metadata. For eLife, the work of creating and sharing excellent metadata aligns with their mission to foster open science and supports their preprint-centred publication model, but it also lays the groundwork for all kinds of exciting potential uses.
Hablamos con Nacho Pérez Alcalde, Vicedirector Técnico de Editorial CSIC, la editorial al mando de ´Boletín Geológico y Minero’, ganadora del Crossref Metadata Award en la categoría de Metadata Enrichment. Miembro de Crossref desde 2008, Editorial CSIC publica 41 revistas en acceso abierto Diamante, y juega un papel esencial en la diseminación del conocimiento científico a nivel internacional. Exploramos lo que este premio ha significado para Editorial CSIC y qué planes para el futuro tienen para seguir mejorando la calidad y uso de sus metadatos.
TLDR: We’ve successfully moved the main Crossref systems to the cloud! We’ve more to do, with several bugs identified and fixed, and a few still ongoing. However, it’s a step in the right direction and a significant milestone, as, whilst it is a much larger financial investment, it addresses several risks and limitations and shores up the Crossref infrastructure for the future.
The American Society for Microbiology (ASM) has earned recognition in Crossref’s Participation Reports for its exceptional metadata coverage among large publishing members––an achievement built on intentional change, technical investment, and collaborative work. In this Q&A, the ASM team shares what that journey looked like, the challenges they’ve tackled, and how centering metadata has helped them better connect research with the global scientific community.
We believe in Persistent Identifiers. We believe in defence in depth. Today we’re excited to announce an upgrade to our data resilience strategy.
Defence in depth means layers of security and resilience, and that means layers of backups. For some years now, our last line of defence has been a reliable, tried-and-tested technology. One that’s been around for a while. Yes, I’m talking about the humble 5¼ inch floppy disk.
This may come as surprise to some. When things go well, you’re probably never aware of them. In day to day use, the only time a typical Crossref user sees a floppy disk is when they click ‘save’ (yes, some journals still require submissions in Microsoft Word).
History
But why?
Let me take you back to the early days of Crossref. The technology scene was different. This data was too important to trust to new and unproven technologies like Zip disks, CD-Rs or USB Thumb Drives. So we started with punched cards.
IBM 5081-style punched card.
Punched cards are reliable and durable as long as you don’t fold, spindle or mutilate them. But even in 2001 we knew that punched cards’ days were numbered. The capacity of 80 characters kept DOIs short. Translating DOIs into EBCDIC made ASCII a challenge, let alone SICIs. We kept a close eye on the nascent Unicode.
Breathing Room
In 2017 the change of DOI display guidelines from http://dx.doi.org.ezproxy.csu.edu.au to https://doi-org.ezproxy.csu.edu.au shortened each DOI by 2 characters, buying us some time. But eventually we knew we had to upgrade to something more modern.
So we migrated to 5¼ inch floppy disks.
5¼ Floppy disk in drive
At 640 KB per disk these were a huge improvement. We could fit around 20,000 DOIs on one floppy. Today we only need around 10,000 floppy disks to store all of our DOIs (not the metadata, just the DOIs). Surprisingly this only takes about 20 metres of shelf space to store.
Typical work from home setup. Getting ready to backup some DOIs!
The move to working-from-home brought an unexpected benefit. Staff mail floppy disks to each other and keep them in constant rotation, which produces a distributed fault tolerant system.
Persistence Means Change
But it can’t last forever. DOIs registration shows no sign of slowing down. It’s clear we need a new, compact storage medium. So, after months of research, we’ve invested in new equipment.
Today we announce our migration to 3½ inch floppies.
If it goes to plan you won’t even notice the change.
