Visualizing Wikibase connections, using wikibase.world queries

by
This entry is part 1 of 3 in the series Wikibase ecosystem

Over the past week I have spent some time writing some code to start running a little bot on the wikibase.world project, aimed at expanding the number of Wikibases that are collected there, and automating collection of some of the data that can easily be automated.

Over the past week, the bot has imported 650 Wikibase installs that increases the total to 784, and active to 755.

I mainly wanted to do this to try and visualize “federation” or rather, links between Wikibases that are currently occurring, hence creating P55 (links to Wikibase) and P56 (linked from Wikibase).

251 Wikibases seem to link to each other, and Wikidata is very clearly at the centre of that web.

Changing the concept URI of an existing Wikibase with data

by

Many users of Wikibase find themselves in a position where they need to change the concept URI of an existing Wikibase for one or more reasons, such as a domain name update or desire to have https concept URIs instead of HTTP.

Below I walk through a minimal example of how this can be done using a small amount of data and the Wikibase Docker images. If you are not using the Docker images the steps should still work, but you do not need to worry about copying files into and out of containers or running commands inside containers.

Wikibase of Wikibases

by

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.

Geospatial search for Wikidata Query Service

by

Geospatial search is up and running for the Wikidata Query Service! This allows you to search for items with coordinates that are located within a certain radius or within a bounding box.

Along side the the map that can be used to display results for the query service this really is a great tool for quickly visualizing coverage.
