• wn instance of the

technology behind Wikidata

• A knowledge base
• Part of the Wikimedia projects
• Structured data
• Linked to other databases
• Multilingual
• Collaborative
• Released under public domain (CC0)
• Based on facts and references
• Made for humans and machines

Wikidata: the basics

• launched 29. October, 2012
• currently more than 56 Mio. data items
• over 20.000 active users

(with more than 1 edit per month)

• The most edited Wikimedia project

A few numbers

Over 56 million data items

• Give more people more access to more knowledge
• A free and open knowledge base that can be read and edited

by both humans and machines

• To provide support inside and outside the Wikimedia projects
• To provide a freely usable repository and a hub

for linked open data

Goals of Wikidata

Structure of the data

Let’s have a look!

• Go to http://wikidata.org
• Search for the item “Berlin” and look at the results

Demo: editing an item

• Sandbox: https://www.wikidata.org/wiki/Q4115189
• Edit a label
• Edit an existing statement
• Add a new value
• Add a new statement
• Add a reference

Build your own instance!

So, what is Wikibase?

• Functionality to create and manage a knowledge base,

including user-defined properties

• A rich JavaScript-based user interface to easily access

and update your data

• A data model that takes knowledge diversity and

multilingual usage seriously

• Exports of the data in a number of formats like JSON,

RDF/XML, N3, and YAML

• Query and display data with SPARQL

Or, to put it simple

Order things in the world. Make them readable and queryable for machines. Link between things and

• concepts. Build the

Semantic Web. Do it the Wiki Way.

Wikibase

• We want more installations outside the

Wikiverse

• Not all data is in scope of the Wikidata
• project. How about a domain-specific

repository?

Why would you want a Wikibase instance?

But seriously.

FactGrid Project

What is it? Why is it cool?

• Dr. Olaf Simons works as a historian at the

University of Erfurt’s Gotha Research Centre. He is the initiator of FactGrid, a database for

• historians. Currently, FactGrid structures

documents around the historical Order of the Illuminati. Blog

Rhizome

What is it? Why is it cool?

Rhizome, an arts organization in New York City, was one of the early adopters of Wikibase, having been using it since 2015 for its archive of born-digital art and digital preservation activities. “In general, we found that classic database systems are very limited for

• ur purposes. Databases for collections in the art and museum sector

tend to use categories that are assigned to classic art: there, an artwork usually has one creator, a single date of creation, it has a physical location and maybe dimensions. The Wikibase sofuware, with its basic schema of items, properties and qualifiers, offers a lot more flexibility to describe an ever-changing field like internet art. You don’t need to have a fixed worldview in place before you can start describing your

• bjects; you can experiment, feel your way into it, and change the

meaning of concepts over time. And even if you have a few ‘outlier

• bjects’—exceptional cases—in your collection, you can still describe

them in a meaningful way, without disturbing the other objects.” Blog

Installation

• We have Docker images
• Setup your own installation including the

Query Service (SPARQL endpoint) on the push of a button

• We included QuickStatements as a tool for

mass uploads

Install with Docker

We have a README-File! Follow the installation description at

https://github.com/wmde/wikibase-docker/blob/master/README-compose.md

Basic installation:

• Clone the repo from github
• run `docker-compose up -d`

You may have to do some config file editing, but your basic example setup is now ready to go.

Demo Time

There is more coming

• Federated Wikibases
• Re-using Wikidata’s
• ntology
• A Wikibase ecosystem

Think about your data

• Think about items and

properties

• You’ll need technical

experts, domain knowledge data experts, and query experts

Questions for you

• What amazing

repositories can you think of?

• We decided to go with

CC0 for data, will you join us?
