Testing times

One of the challenges that we face in Labs and Research at Crossref is that, as we prototype various tools, we need the community to be able to test them. Often, this involves asking for deposit to a different endpoint or changing the way that a platform works to incorporate a prototype. The problem is that our community is hugely varied in its technical capacity and level of ability when it comes to modifying their platform.

Mending Chesterton's Fence: Open Source Decision-making

When each line of code is written it is surrounded by a sea of context: who in the community this is for, what problem we’re trying to solve, what technical assumptions we’re making, what we already tried but didn’t work, how much coffee we’ve had today. All of these have an effect on the software we write. By the time the next person looks at that code, some of that context will have evaporated.

Credential Checking at Crossref

It turns out that one of the things that is really difficult at Crossref is checking whether a set of Crossref credentials has permission to act on a specific DOI prefix. This is the result of many legacy systems storing various mappings in various different software components, from our Content System through to our CRM. To this end, I wrote a basic application, credcheck, that will allow you to test a Crossref credential against an API.

Subject codes, incomplete and unreliable, have got to go

Subject classifications have been available via the REST API for many years but have not been complete or reliable from the start and will soon be deprecated. dfdfd The subject metadata element was born out of a Labs experiment intended to enrich the metadata returned via Crossref Metadata Search with All Subject Journal Classification codes from Scopus. This feature was developed when the REST API was still fairly new, and we now recognize that the initial implementation worked its way into the service prematurely.

Warnings, Caveats and Weasel Words

Most of the experiments linked to here are running on R&D equipment in a non-production environment. They may disappear without warning and/or perform erratically. If one of them isn’t working for some reason, come back later and try again.
