The following is a guest post by Bob Mesibov. Do you know the party game "Telephone", also known as "Chinese Whispers"? The first player whispers a message in the ear of the next player, who passes the message in the same way to a third player, and so on. When the last player has heard the whispered message, the starting and finishing versions of the message are spoken out loud. The two versions are rarely the same.
Holly Bik (@hollybik) has an opinion piece in PLoS Biology entitled "Let’s rise up to unite taxonomy and technology" https://doi.org/10.1371/journal.pbio.2002231 (thanks to @sjurdur for bringing this to my attention). It's a passionate plea for integrating taxonomic knowledge and "omics" data.
Notes to self on web map-style tree viewers. The basic idea is to use Google Maps or Leaflet to display a tree. Hence we need to compute tiles. One approach is to use a database that supports spatial queries to store the x,y coordinates of the tree. When we draw a tile we compute the coordinates of that tile, based on position and zoom level, do a spatial query to extract all lines that intersect with the rectangle for that tile, and draw those.
I've been viewing Apple's Knowledge Navigator concept video from 1987 and it's striking how much of this we have today, and yet how far away we are from the complete vision. For some background on this promotional video see The Making of Knowledge Navigator.
Nico Franz and Beckett W. Sterner recently published a preprint entitled "To Increase Trust, Change the Social Design Behind Aggregated Biodiversity Data" on bioRxiv http://dx.doi.org/10.1101/157214 Below is the abstract: Below I respond to some specific points that annoyed me about this article, at the end I try and sketch out a more constructive response.
GBIF is running its Ebbe Nielsen Challenge for the third successive year. This year the title is Liberating species records from open data repositories for scientific discovery and reuse. To quote from the Challenge background on Devpost: In essence, the 2017 Challenge is to develop tools to discover these biodiversity-relevant datasets, and make them available to GBIF.
Yes, this post is indeed an attempt to fit as many buzzwords that I don't really understand into the title. I've been playing around with Glitch, which is a delightful project from Fog Creek (makers of Trello and co-creators of Stack Overflow). On first glance Glitch looks weirdly retro, and it took a little while for me to get the hang of things. Bit it's fun and very powerful.
For my own use more than anything else I've started creating a list of Wikidata SPARQL queries here. I personally don't find Wikidata's data model particularly easy to grasp, so one way to learn is to take the example queries on the Wikidata Query site and mess about with them. For those interested in taxonomic data Wikidata is quite rich in content.
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.
Following on from earlier posts exploring how to map DNA barcodes and putting barcodes into GBIF it's time to think about taking advantage of what makes barcodes different from typical occurrence data. At present GBIF displays data as dots on a map (as do I in http://iphylo.org/~rpage/bold-map/). But barcodes come with a lot more information than that.
