2019:Poster session/Wikidata visualization by predefined queries related to one topic - a case study
 | This is an Accepted submission for the Poster space at Wikimania 2019. |
Description
[edit | edit source]How can free data be displayed in web projects so that the general public can also use it?
At "Archivführer - Deutsche Kolonialgeschichte" we chose a way to present data of one main topic in several contexts.
This is based on a hierarchical set of predefined SPARQL queries. The queries differ between classes (what kind of information is queried?) and reference objects (what object is queried?).
Using this way, it is also possible, for example, to obtain queries on members of an organisation, which in turn is listed in a larger context (e.g. persons who worked in the district administration of Yaoundé, which was a part of the administration in German Cameroon).
In the case of statements that are supported by references, corresponding notes are provided.
The tool is completely client-based and was written in Javascript/jQuery.
The use of predefined queries offers several advantages:
- All data is stored in Wikidata and can be supplemented by the community at any time.
- Visitors can benefit immediately and do not need to develop SPARQL queries, which are complicated for them.
- The results are related to each other. In their entirety, they provide an insight into the main topic (here: German colonial history).
