Finding related content

Several components can ideally display content from sources across the web. The goal is to enrich Wikimedia projects with content from the sources using the available tools. We currently read some image sources, but the content could ideally include newspapers, sounds, archival material, films, videos, literature, magazines, scientific articles etc.

The source content could be used in many ways: It could be imported as such, the metadata could be consolidated with metadata of similar objects from other outlets, or the data/metadata could be used to enrich items in Wikimedia projects. In these scenarios the open projects (Wikimedia, OSM) are seen as central databases which store the collectively enriched data and can serve that back to the institutions.

Selecting data for the query

Labels and aliases in all languages
- Not all languages can be handled by an API. The unsuitable ones need to be filtered our in the preprocessing phase.
- If the main languages of the API are known, the query can use labels of that language as a primary option.
- Preprocessing can collect all necessary values and send to the local API. The local component for a specific API can arrange the data suitable for each API, for example concatenate the query strings in different ways, using AND or OR.
Item's location can be used to narrow down search results or to distinguish from namesakes.
The dates of the item can be used to narrow down search results. This is especially useful with maps.
For maps the zoom level or the scale can be calculated using the size of the area the item covers.

Metadata roundtripping

GLAM makes available images and their metadata through their public API. Wikidocumentaries uses many Wikidata properties from the current topic to query that.
When reading the data through the Wikidocumentaries API, the metadata is normalized using a different transformation for each GLAM.
The metadata from different GLAMs is displayed in a uniform format in the Wikidocumentaries metadata display as strings.
When an image is saved to Wikimedia projects, users can reconcile string values with Wikidata items. String values can be saved as well, they will be available for reconciling later.
In the Wikidocumentaries metadata interface, the string values are replaced by reconciled Wikidata items. Differences between the source data from the GLAM and Wikidata, such as recent changes in the GLAM's metadata, can also be highlighted.
Maybe the GLAM could query Wikidocumentaries for changed information?

Consolidate data from different sources for the same item

Especially if Wikidocumentaries decides to store images or their metadata locally, these scenarios become available. Similar images from different sources can be detected. Their metadata can be compared, and the user is asked to verify the correct information. The updated data is saved in the central repository (Wikimedia Commons) with a reference to the source that provided this information. One of the information types that can be compared is the copyright status.
