Quick notes to self following on from a conversation about linking taxonomic names to the literature. There are different sorts of citation: Paper cites another paper Paper cites a dataset Dataset cites a paper Citation type (1) is largely a solved problem (although there are issues of the ownership and use of this data, see e.g. Zootaxa has no impact factor.

This blog post provides some background to a recent tweet where I expressed my frustration about the duplication of DOIs for the same article. I'm going to document the details here.

Last week I was at WikiCite 2017, a fascinating three day event in Vienna. Wikicite is "a proposal to build a bibliographic database in Wikidata to serve all Wikimedia projects", and is attracting increasing attention from academics, librarians, publishers, data geeks, and others. You can get a sense of the project by following @WikiCite on Twitter.

In a recent Twitter conversation including David Shorthous and myself (and other poor souls who got dragged in) we discussed how to demonstrate that adopting JSON-LD as a simple linked-data friendly format might help bootstrap the long awaited "biodiversity knowledge graph" (see below for some suggestions for keeping JSON-LD simple). David suggests partnering with "Three small, early adopting projects". I disagree.

A decade ago (OMG, that can't be right, an actual decade ago) I created "iSpecies", a simple little tool to mashup a variety of data from GBIF, NCBI, Yahoo, Wikipedia, and Google Scholar to create a search engine for species.

On Friday I discovered that BHL has started issuing CrossRef DOIs for articles, starting with the journal Revue Suisse de Zoologie . The metadata for these articles comes from BioStor. After a WTF and WWIC moment, I tweeted about this, and something of a Twitter storm (and email storm) ensued: To be clear, I'm very happy that BHL is finally assigning article-level DOIs, and that it is doing this via CrossRef.

I'm going to the TDWG Identifier Workshop this weekend, so I thought I'd jot down a few notes. The biodiversity informatics community has been at this for a while, and we still haven't got identifiers sorted out. From my perspective as both a data aggregator (e.g., BioNames) and a data provider (e.g., BioStor) there are four things I think we need to tackle in order to make significant progress.

I had a long Twitter conversation with Terry Catapano (@catapanoth) today, and as can happen with a distracted stream of tweets, I think we were a little at cross purposes. This blog post is an attempt to unpack the debate.

In a previous post (Learning from eLife: GitHub as an article repository) I discussed the advantages of an Open Access journal putting its article XML in a version-controlled repository like GitHub. In response to that post Pensoft (the publisher of ZooKeys ) did exactly that, and the XML is available at https://github.com/pensoft/ZooKeys-xml. OK, "now what?" I hear you ask.

I've stumbled on a case where two different publishers have issued different DOIs for the same articles. In this case, Springer and J-State both publish the Japanese Journal of Ichthyology (ISSN 0021-5090). The following article: is published by Springer with the DOI http://dx.doi.org/10.1007/BF02914322, and this DOI is registered with CrossRef. J-Stage publish the same article, with the DOI (http://dx.doi.org/10.11369/jji1950.36.196).
