I recently solved several annoying problems that I’d been having when using SPARQL queries to acquire data from Wikidata. My success inspired me to write a comprehensive Python class that will reliably carry out every kind of SPARQL Query and Update, with defaults to easily make SELECT queries to Wikidata.
Making SPARQL queries to Wikidata using Python
Birding in Puerto Rico
After recently making a trip to Puerto Rico that was primarily focused on bird watching, I decided to write a blog post to pass on some of what we learned. Much of the information that we got from books or the Internet was outdated or incorrect, so hopefully this post will help others to have an easier time finding good places to bird there.
QT Py RP2040 workshop
I’m really excited to be working with Vanderbilt Science and Engineering librarian Francisco Juarez to develop a workshop series to teach participants to program the QT Py RP2040 microcontroller using CircuitPython.
VanderBot 1.9 supports somevalue
One of the issues I discussed at my recent talk in the Art in Context: Identity, Ethics, and Insight symposium was the problem of representing anonymous artists in knowledge graphs. The solution that the Wikidata community has accepted is to associate a P170 (creator) claim with a somevalue snak having a P3831 (object has role) qualifier value of Q4233718 (anonymous). In RDF, this corresponds to a blank node and Wikidata claims using somevalue are represented by blank nodes in the Query Service.
Optimizing Wordle guesses
I’ve recently started playing the viral word game “Wordle”. After numerous discussions among family members about guessing strategy, I decided to spend some time over the holiday weekend writing a Python script to play with different guessing algorithms and strategies.

Building an Omeka website on AWS
I recently finished building an Omeka digital collection for images from the files of Bassett Associates, a landscape architectural firm that operated for over 60 years in Lima, Ohio. This award-winning firm, which disbanded in 2017, was well known for its zoological design work and also did ground-breaking work in incorporating storm water retention as part of landscape site design.
Publication of subjectPart and subjectOrientation controlled vocabularies
On 26 April 2023 the Executive Committee of Biodiversity Information Standards (TDWG) ratified two new controlled vocabularies to become a part of the Audiovisual Core standard. This marks the culmination of hundreds of hours of work on my part over many years.
Structured Data in Commons and wikibase software tools
In February, I gave a presentation at the Wikibase Working Hour about how my VanderBot tool for uploading data to Wikidata could be used more broadly with any kind of wikibase. One example I gave was using it to upload Structured Data on Commons (SDoC) statements that describe what is depicted in a media file, since SDoC is just another wikibase instance.
