WikidataCon 2017

WikidataCon, the first conference dedicated to the Wikidata community took place in Berlin on October 28th and 29th. How to summarize this event? It was a huge success, both from the point of view of the community and the organization team, and we hope that you enjoyed the event as much as we did.

We can already deliver some amazing numbers: 200 attendees, including 50 helpers, 78 speakers, 50 scholars, not including 20+ plushies. We had more than one hundred sessions with a total of 40 hours of video recorded, we had 20 birthday presents, we had 43 countries represented and almost as much sweets on the sweets table!

We are especially happy that WikidataCon may very well be one of the best documented Wikimedia events. Thanks to the wonderful people at C3VOC, recordings of presentations were online just hours after they were given! The list of all recordings is impressive.

Data Partnerships in Wikidata: Project Durchblick

Dieser Beitrag ist auch auf Deutsch verfügbar.

Dr. Georg Schelbert works at the Humboldt-Universität Berlin at the Institut für Kunst- und Bildgeschichte (IKB) as the head of the media library. His project „Durchblick“ may be translated as „Through the Looking-Glass“ in more than one sense: As it is about glass slides, it literally deals with glass you can see through.  But the project is also about gaining insights from a vast collection of cultural assets, almost like exploring the wonderland hidden in it. Project Durchblick makes extensive use of Wikidata. This kind of data partnership does not come in the form of a data donation, but rather as using Wikidata as a hub for other data collections in order to provide objects in collections with common identifiers.

What is Durchblick all about? What kind of collection is that and how did it start?

We decided to call our project „Durchblick!“, as we faced the task to explore a large number of glass slides that had been in use for many decades in the department for the history of art at the Humboldt-Universität and make them accessible again. 

Every institute for the history of art has more or less large collections of slides that are used in lectures and seminars. Primarily, two formats are used: First, the larger glass slides where a black and white film is applied directly to a pane of the format of 8,5 x 10cm that were produced since the late 19th until the middle of the 20th century. And then the so-called small picture slides that emerged from the 35mm color film format as used in movie theaters that have been in use from the 1940s until today.  We focus only on the glass slides with Durchblick. The Berlin collection is one of the oldest and largest, as some of the Berlin professors of art history like Herman Grimm (son of Wilhelm Grimm) or Heinrich Wölfflin discovered and used the potential of projected photographs quite early. Thus, the collection also reflects the interests of famous representatives of the field in research and teaching. Today, after damages caused by wars, a significant amount consists of replicas and additions made in the 1950s, however over the the time also many interesting new themes were added, such as East German or Soviet art, urban development, or even traffic planning.

Data Partnerships with Wikidata: beaTunes

Dieser Beitrag ist auch auf Deutsch verfügbar.

Wikidata data partnerships happen in many ways. While data donations are a way for institutions, organisations or individuals to contribute content to the free knowledge-base, re-use of data in applications is just as interesting as it contributes to the eco system of Free Knowledge and thus gives more people more access to more knowledge.

beaTunes is an application for the Mac that lets you build playlists for your music collection. It uses Wikidata in various ways to enrich the application.

The free license for Wikidata allows commercial re-use as well.  We talked with Hendrik Schreiber of beaTunes about how to use Wikidata in a commercial software product.

Ladies That FOSS — Welcoming 35 women coders into the FOSS movement and that was just the beginning

German summary: Ladies That FOSS war ein Hackathon gerichtet an Frauen, die Interesse an Freier und Open Source Software (FOSS) haben, aber noch nicht an konkreten Projekten beteiligt sind.

by Julia Schuetze

Ladies That FOSS was an open source hackathon by Wikimedia Deutschland e.V. in October 2016 continuing as a meetup starting from March 15th 2017.

In October 2016 Wikimedia Deutschland e.V. held its first hackathon aimed at women and nonbinary coders who are interested in Free and Open Source Software. The majority of them had one thing in common: they have never contributed to the FOSS world but were eager to find out what all the fuss in FOSS is about. Weiterlesen »

Being a Volunteer Developer for Wikimedia projects: An Interview with Greta Doçi

Interview by Sandra Muellrick. This blog post is also available in German.

As a volunteer, Greta has been active in the Wikimedia movement for only a few years. She gives talks about Wikidata and is involved with Open Source development. In this blog post we want to introduce both her and the many opportunities the Wikimedia movement offers to try out new things, learn, and improve.

“Everything I know I try to put online to share e.g work with MediaWiki, queries or editing in Wikipedia or Wikidata. ”

For three years now, Greta has been editing Wiki projects on almost every afternoon. She is enthusiastic about bringing Free Knowledge to the world out of her native country of Albania. She’s been an editor for Wikipedia for over three years, and for more than one and a half year she’s been active on Wikidata. She also served on the board of the Albanian user group. Apart from her day job as an IT expert at an Albanian state organization, she organizes Wikidata workshops as well as the Albanian edition of the “Wiki Loves Monuments” photo contest, teaches university students on how to use Wikipedia, and for 3 months now she’s been teaching herself how to contribute code to MediaWiki.

“I love these things. That’s why I’m volunteering.”

She started to volunteer for charity causes at a young age. It’s important for Greta to produce something meaningful, finish projects, and have an impact on society. She loves to learn things, share knowledge and teach others. This is why she feels right at home at the Wikimedia movement. Weiterlesen »

Software product management as an internship: Learning about the real world at Wikimedia Deutschland

German summary: Glorian Yapinus aus Indonesien hat gerade sechs Monate Praktikum in der Software-Entwicklung bei Wikimedia Deutschland hinter sich. Hauptsächlich arbeitete er mit Lydia Pintscher zusammen, der Produktmanagerin von Wikidata. Seine Motivation war es, Produktmanagement mit praktischen Erfahrungen in einem realen Projekt zu lernen. Wir haben ihn zum Ende seines Praktikums zu seinen Erfahrungen befragt. Das Interview fand auf Englisch statt, der Sprache, die Glorian auch in der täglichen Arbeit bei Wikimedia Deutschland benutzte.

Glorian Yapinus just spent 6 months at Wikimedia Deutschland as an intern in the software development department. Working together with Lydia Pintscher, the product manager of Wikidata, he was driven by his wish to work on a real world project. This is his story.

Hi, Glorian. Tell us a bit about your background. Where are you from, what do you study?

Hi :)
I come from Indonesia, a beautiful island country located in Southeast Asia. I love building things. As time went by, I discovered that apart from loving to build things, I am also drawn to technology. This is the reason why I did my Bachelor study in Information Technology (IT). Back then, I wished that through this study, I could learn how to develop cool games and applications.

However, it turned out, I got hooked on a subject called software product management. Software product management is an area in IT which encompasses most aspects in software development ranging from researching user requirements to translating those requirements into new software.

Because I wanted to develop my knowledge and skills in software product management, I decided to come to Germany in order to pursue a Master degree in Software Engineering and Management at Heilbronn University. In this Master study, I learned about a different facet of IT which I did not learn during my Bachelor study, that is, how to manage software projects. Arguably, project management is an integral part of software product management and a must skill for software product managers.

At some point during the study, I realized I have to get my hands wet on software product management. In other words, I was looking for a practical experience in software product management, in order to complement what I have learned in the university. Afterwards, I found the product management intern vacancy in Wikimedia Deutschland. I tried to go for this opportunity and I got the internship. That was how I wound up here.

10 cool queries for Wikidata that will blow your mind. Number 7 will shock you.

Dieser Blogpost ist auch auf Deutsch verfügbar.

Wikidata is an open knowledge base that collects facts (statements) on pieces of knowledge (items). It is run by the Wikimedia Foundation, developed by a team led by Wikimedia Deutschland, and tended and cared for by a global community of volunteers. Unlike Wikipedia, that contains knowledge collected by volunteers written in free form, it is machine-readable and pieces of knowledge and can be queried in relation to each other.

Dozens of application already use the knowledge base. One particularly cool way to access knowledge in Wikidata is through queries in the SPARQL query language. Just a little knowledge of SPARQL goes a long way to query for facts and relationships – thus opening new horizons and rearranging knowledge in a totally new way.

With SPARQL, the possibilities are virtually endless. Follow along for 10 cool queries: Weiterlesen »

I don’t have to find tasks. Tasks are coming to me. Being a Volunteer Developer for Wikimedia projects: An Interview with Tpt

German summary:

“Ich suche mir keine Aufgaben. Normalerweise kommen die Aufgaben einfach zu mir,” sagt Thomas, freiwilliger Entwickler für MediaWiki. Wie sieht eigentlich die ehrenamtliche Tätigkeit eines freiwilligen Entwicklers aus? Wer steckt hinter dem Code und den Features, die tagtäglich von vielen Editoren benutzt werden? Julia Schuetze setzte sich mit Thomas aka tpt zusammen, um einen Einblick in die Programmiertätigkeit eines Freiwilligen zu bekommen.

An interview by Julia Schuetze with Thomas Pellissier-Tanon aka Tpt

“I work on the software behind Wikipedia!” That’s what Thomas aka (Tpt), a Volunteer Developer from France, tells his friends if they ask him about what he does in his free time. Up to ten hours per week he dedicates to free knowledge that way.

In the past two months, I got the chance to talk to some of our volunteer developers about their experience with the Wikimedia movement. I’d like to share Thomas’ story, his views, concerns, ideas and accomplishments with you.  

Thomas started in 2009 when he was still in high school. A passion for egyptian history and pharaohs inspired him to contribute to the French Wikipedia. Back then, programming was new to him. He started by writing templates and by learning how to use the functions around Wikipedia.

Starting is not easy. Wikipedia is a project created, maintained and developed by millions of people. Thousands contribute at least once a month. People commit, some stay for longer, some only for a short time. I wondered what made Thomas stick around and become a very innovative volunteer developer in our community for over seven years now.

MediaWiki: “huge, complex and often ugly”

The first few months can be rocky, he says. It was an exploration for him because MediaWiki, the free and open source wiki application, which stores the content into databases, “is huge, complex and often ugly.” “It was a lot of reading code to see how it works and how all the pieces are fitting together,” Thomas remembers. “Some of that can act as barriers. Especially for developers who are not familiar with Wikis,” he explains. It was quite difficult to write code matching MediaWiki standards and conventions and with a good enough level of quality at first.”
