Citation.js: Wikidata Subclasses I am in the process of creating a better way to map CSL types to Wikidata types together with Jakob Voß, and while listing all subtypes of web page, I came across a number of these cases (link): #defaultView:Graph SELECT ?a ?aLabel ?b ?bLabel WHERE { wd:Q58803899 wdt:P279* ?a . ?a wdt:P279 ?b . FILTER EXISTS { ?b wdt:P279* wd:Q386724 . } SERVICE wikibase:label { bd:serviceParam

Citation.js: Showing Blogger Posts on a Different Site I made a Material-themed page showing Citation.js blog posts from Blogger. It supports pagination, tags, search and linking individual posts. Since it’s a single, static page I can’t support meta and link tags for metadata, that would require JavaScript which indexers don’t run.

Modern Altmetric badges I recently found myself working with Altmetric badges again, and I realized how cumbersome it can be to work with scripts. The Altmetric badges can only be added by using their JavaScript library, while it would be a lot more user friendly to have a simple URL that embeds the badge, preferably even an image.

Citation.js: Use Case for a Wikidata GraphQL API Citation.js has supported Wikidata input for a long time. However, I’ve always had some trouble with the API.

Journal Metadata: Authors & Institutions I finished the General Plugin system for Citation.js a few days ago (more on that later), so I could finally publish a new beta release. Now, after that half-finished piece of code had been blocking other work for a long while, I can at last start… fixing bugs, and closing other items in the backlog.

Debugging: Deja Vu I’m going to share some stories on debugging with you, because I’m proud of them. After writing up the first story, I’m no longer particularly proud, but I still want to share the story. Here’s the first: a bug that seemed quite familiar.

I promised more photos in the previous post, so here they are. Penicillium: Detail With conidiophores Detail of conidiophores More fungi: Cat brains: This post is part of a series.

Citation.js Version 0.4 Beta: New Docs and Input Plugins It’s been a while. Really. But now it’s back, with a new release: v0.4.0-0, the v0.4 beta. Below I explain some of the changes in this release, and then the road-map of Citation.js for v0.4 and v0.5. Also, Citation.js has a DOI now: Also, @jsterlibs tweeted about Citation.js. Release Input plugins The main change in this release, is the addition of input plugins.

Below is part two of a small series on ctj rdf, a new program I made to transform ContentMine CProjects into SPARQL-queryable Wikidata-linked rdf. Here’s a more detailed example. We are using my dataset available at 10.5281/zenodo.845935. It was generated from 1000 articles that mention ‘Pinus’ somewhere. This one has 15326 statements, whereof 8875 (57.9%) can be mapped, taking ~50 seconds.

Below is part one of a small series on ctj rdf, a new program I made to transform ContentMine CProjects into SPARQL-queryable Wikidata-linked rdf. ctj has been around for longer, and started as a way to learn my way into the ContentMine pipeline of tools, but turned out to uncover a lot of possibilities in further processing the output of this pipeline (1, 2). The recent addition of ctj rdf expands on this.

Citation.js: Endpoint on RunKit A while back I tweeted about making a simple Citation.js API Endpoint with RunKit.
