Snapshot Tool

Mon, 01 Jan 0001 00:00:00 +0000

This is a command-line tool for working with DataCite and Crossref data dumps. It can convert between formats, combine snapshots and produce statistics.

Unicode in DOIs

Sun, 22 Dec 2024 00:00:00 +0000

The previous post looked at how long DOIs are. One of the questions was:

Do UTF-8 encodings from Unicode characters make any difference on the statistics around DOI length?

Scholarly Identifiers Rust Library

Mon, 01 Jan 0001 00:00:00 +0000

A Rust library for parsing, validating and normalising a selection of scholarly identifiers (DOI, ORCID, ROR, ORCID, ISBN), etc. It’s work in progress, with more identifiers being added.

How long is a DOI?

Sun, 22 Dec 2024 00:00:00 +0000

In 2024 DataCite released their first public data file. It’s easy to get a copy. Crossref have made a data dump available for the past few years.

Having both files available opens up some interesting possibilities in comparing and combining the two data sources.

The most obvious place to look is the DOIs themselves…

… and the simplest question you could ask is “How long is a DOI?”

Chaser

Tool to keep a local SQLite database up to date with changes from Crossref.

SPPIES: A slack group for Scholarly Programmers

Mon, 04 Nov 2024 00:00:00 +0000

Are you interested in the technical side of scholarly publishing technology and infrastructure? If so, you’re welcome to join the SPPIES Slack group.

SPPIES is short for Scholarly Publishing Programmers and Infrastructure Enthusiasts, in homage to programmers’ love of acronyms. One of the ‘P’s is silent.

Falsehoods Programmers believe about DOIs

Wed, 30 Oct 2024 00:00:00 +0000

DOIs, or Digital Object Identifiers, are everywhere, for a given value of ’everywhere’. They are the identifiers used to identify and link research outputs, and a lot more besides.

Humans are good at spotting patterns, and with something as ubiquitous as DOIs, there are plenty of patterns to spot. However, with hundreds of millions of DOIs and decades of history, it pays not to make generalisations.

These all cropped up in my 10 years at Crossref. Either observed in the scholarly community using DOIs, or when writing software to find and handle DOIs.

Appropriately Technical

Tue, 01 Oct 2024 00:00:00 +0000

The word ’technical’ hasn’t always had a great reputation. Think of phrases like ’technically correct’, ’technical details’, or ‘acquitted on a technicality’. It’s easier to think of more negative uses than positive ones. I think there are a couple of reasons for that.

Five principles for community altmetrics data

Tue, 29 May 2018 00:00:00 +0000

I presented these five principles at the altmetrics18 workshop. You can read the paper submitted to the workshop here. This post is a few years old, but all the ideas still stand up. At the time I was building Crossref Event Data, and discussing what it would take to build an data model that would support community-generated bibliometrics. A lot has changed since, but I think the principles are still relevant today.
