[http://www.wikiedia.org Wikipedia] is an online encyclopedia running software called MediaWiki. You might have seen websites before that look like Wikipedia. They run MediaWiki.

Wikipedia is a project of the WikiMedia Foundation, which also - quite logically - develops the software MediaWiki. They have many more projects, with one called [http://www.wikidata.org Wikidata]. Wikidata has the same collaborative dynamics as Wikipedia, and much of the same feel. The main difference is that the focus is in maintaining a collaborative database of facts. This is done using an extension of MediaWiki called [https://wikiba.se/ Wikibase], yet another project of the Foundation.

In our project, we have decided to use MediaWiki together with its extension Wikibase, to maintain a collaborative database of actors in the personal data ecosystem.

Wikibase uses three main concepts:
* item
* property
* statement

For instance, {{Q|101}} is an item. Click on it and have a look. To an item you can attach statements. An example such statement is the linkage:

{{Q|101}} -- {{P|3}} -- {{Q|96}}

In this statement, {{P|3}} is a property. So a statement is basically a triple (item, property, item).

One can also qualify a statement through a "qualifier", and add a "reference" for a statement.
