This past year was relatively quiet for Citation.js, as changes to the more prominent components (BibTeX, RIS, Wikidata) start to slow down. I believe this is a good sign, and that it indicates the quality of the mappings is high.

Working on translating a key to the European shield bug nymphs (Puchkov, 1961) I thought I would look for pictures of the earlier life stages (nymphs, Fig. 1) of shield bugs (Pentatomoidea) on iNaturalist and found few observations actually had the life stage annotation.

Ever since I found out about Structured Descriptive Data (SDD) I keep coming back to it. Right now I am planning to make two identification keys, one translated and modernized from a 1961 publication for which I have not found a good alternative, and one completely de novo (well, nearly). In both cases, I started writing out the key in a word processor with a numbered list and tabs and manual alignment etc., but in both cases that

Last november I wrote a blog post about how to model the taxonomic coverage of identification keys. I wanted to model this coverage to be able to determine to what extent an identification key applies to a given observation or specimen, for use in my Library of Identification Resources project. For the same project I also find it useful to be able to archive identification keys.

Following up on the previous two updates this year ( Version 0.5 and a 2022 update and Version 0.6: CSL v1.0.2 ), here are some updates from the second half of 2022, as well as some statistics. Sapygina decemguttata , a small wasp, observed July 8th, 2021 Changes The mappings of the Wikidata plugin were updated, especially to accomodate for software. The default-locale setting of some CSL styles is now respected.

The website of the Library of Identification Resources has a new feature: a map view. The resources in the catalog are associated with a geographic scope to approximate which species in a taxonomic group can be identified. These geographic scopes are usually countries or continents but can also be subdivisions within countries, multinational ecological regions like mountain ranges, and biogeographical realms.

The main feature of the Library of Identification Resources is the description of the identification key (or matrix, reference, etc.). This description should on its basis specify when the key can or should be used.

Since around this time last year, I have been working on creating a library of identification resources. Here, “identification resources” are identification keys, multi-access (matrix) keys, other works that can aid in the identification of species. The project is managed on GitHub: https://github.com/identification-resources.

Since the citation-js npm package was first published, version 0.6 is the first major version of Citation.js that did not start out as a pre-release. Version 0.3 itself spent almost 6 months in pre-release, but only received updates for less than half a month. Version 0.4 spent more than a year in pre-release and received updates for about 4 months.

Last semester I followed some courses at a different university, and went through the process of collecting login credentials and multi-factor authentication tokens and familiarizing myself with a network of university systems all over again.

Version 0.5.0 Version 0.5.0 of Citation.js was released on April 1st, 2021. BibTeX and BibLaTeX After the update to the Bib(La)TeX file parser, described in the earlier BibTeX Rework: Syntax Update blog post, the mapping of BibTeX and BibLaTeX data to CSL-JSON was also updated. The mapping is now split in two, one for BibLaTeX (which is backwards-compatible with BibTeX) and one for BibTeX.
