The Wikibase registry was one of the outcomes of the first in a series of Federated wikibase workshops organised in partnership with the European research council.
The aim of the registry is to act as a central point for details of public Wikibase installs hosted around the web. Data held about the installs currently includes the URL for the home page, Query frontend URL and SPARQL API endpoint URL (if a query service exists).
During the workshop an initial data set was added, and this can be easily seen using the timeline view of the query service and a query that is explained within this post.
While working on a new Mediawiki project, and trying to setup a Kubernetes cluster on Wikimedia Cloud VPS to run it on, I hit a couple of snags. These were mainly to do with ingress into the cluster through a single static IP address and some sort of load balancer, which is usually provided by your cloud provider. I faffed around with various NodePort things, custom load balancer setups and ingress configurations before finally getting to a solution that worked for me using ingress and a traefik load balancer.
Below you’ll find my walk through, which works on Wikimedia Cloud VPS. Cloud VPS is an openstack powered public cloud solution. The walkthrough should also work for any other VPS host or a bare metal setup with few or no alterations.
Back in 2016 I wrote a short hacky script for taking HTML from facebook data downloads and adding any data possible back to the image files that also came with the download. I created this as I wanted to grab all of my photos from Facebook and be able to upload them to Google Photos and have Google automatically slot them into the correct place in the timeline. Recent news articles about Cambridge Analytica and harvesting of Facebook data have lead to many people deciding the leave the platform, so I decided to check back with my previous script and see if it still worked, and make it a little easier to use.
This is a belated post about the Wikibase docker images that I recently created for the Wikidata 5th birthday. You can find the various images on docker hub and matching Dockerfiles on github. These images combined allow you to quickly create docker containers for Wikibase backed by MySQL and with a SPARQL query service running alongside updating live from the Wikibase install.
A setup was demoed at the first Wikidatacon event in Berlin on the 29th of October 2017 and can be seen at roughly 41:10 in the demo of presents video which can be seen below.
