Examples of searches

Simple search

Indexed search

Indexed and free serach, crossed

Searches can be made by free or indexed search. Results are displayed by chrological order with thumbnails. Links on thumbnails open a viewer with the image hosted on Wikimedia Commons.

It is possible to filter the results by type (painting, sculpture, print…) or to specify a period as criterion.

By default, without criterion, a random selection is displayed.

Besides with the Cosmos it is possible to discover the artworks by indexation (par type d’œuvre, creator, movement, genre, collection…).


Under each result image are mentionned the title, the creator(s) (property p170) and the collection (property p195) or the location (property p276) when these information are on Wikidata.

Four icons can be directly associated with the work (when information is on Wikidata):

Artworks selection

The Wikidata extraction contains currently (April 2015) more than 46 000 artworks (10 000 in May 2014) with more than 20 000 images (7 000 in May 2014). This extraction is regularly automatically updated from Wikidata on the basis of the nature of the items (property p31) and corresponds to the following types of visual artworks:

All data used in Crotos come from Wikidata, free database, collaborative and multilingual.

Data are published on Wikidata manually or via robots, (like this one to migrate data from DBpedia as explained here: Voyage de DBpedia en Wikidata à bord d’un bot [in French]), or by creating new items via robots [in French], or via semi-automated publishing tools like Autolist or Quick Statements.

Contribution mode

The project has a contribution mode, useful for identifying missing information with facets. For example, artworks without English title. So if the envy takes you, do not hesitate to indulge yourselves.

Finally, source is on github and the database of Crotos can be downloaded ; both are under Free Licence.

Do not hesitate to make remarks, criticisms or suggestions to benoit (a) or elsewhere.
