Semantic Wikibase: Using Wikidata in Your Wiki
Last updated on 2019-12-21
Imagine the data from Wikidata being available in your own wiki for you to query, visualize and enrich. Imagine you could use all the standard Semantic MediaWiki tools such as interactive inline visualizations on this data.
Sadly for now imagination is all we have. This article outlines functionality which we (and everyone we talked to) think would be of great value. We are looking for funding so we can make it a reality.
The goal of this project is to increase consumability of data from Wikidata in other wikis.
The goal is achieved by creating a bridge between Wikibase, the software that runs Wikidata, and Semantic MediaWiki (SMW). This bridge would build on top of Wikibase federation and allow using data from Wikibase in SMW just like native SMW data. Such a connection is relatively simple and brings with it many time-tested features not currently available for Wikibase data.
- Consumption of data from Wikidata in typical structured wikis
- Enriching local data sets with data from Wikidata
- Visualizing data from Wikidata with all SMW visualization formats
- Using existing SMW tooling to analyze and work with Wikidata data
- Creating (simplified) projections of Wikidata data
- Comparing local values with those in Wikidata
- Doing all the above with data from any Wikibase instance
The project would create a foundation for further integrations like contributing data back to Wikidata.
We would create a new Semantic Wikibase extension for MediaWiki. This extension
- Supports importing data from Wikidata/Wikibase into Semantic MediaWiki
- Builds on top of SMW so existing tools and visualization formats can be used
- Provides tools to select which entities are imported
- Provides tools to project the data and map to local data models
- Takes care of (optionally) updating the imported data
- Allows linking local properties and concepts to Wikidata ones
We would follow Agile practices, meaning that we would be refining and extending the list of functionality to deliver through the development process by testing assumptions and soliciting feedback from stakeholders.
We are uniquely suited to develop this project since no one else has significant technical experience with both Wikibase and SMW. In particular, Jeroen De Dauw is one of the SMW maintainers. He also worked on Wikibase for about 5 years in a senior technical position, making more code changes than anyone else.
We expect that to get project right we need between half a year and one year with two people (FTEs). The required time will depend on the exact scope and includes paying a proper amount of attention to usability and sustainability. This translates into a budget between 200k EUR and 70k EUR.
We think this is an insanely cheap price tag for the value this project would bring. For comparison, the Wikimedia Foundation spends several millions a year on software development, with the full yearly cost of a single employee exceeding 70k EUR.
If you can fund (part) of this project or have ideas on how we can get it funded, please get in touch. We'd also like to hear from you if you have a use case that would greatly benefit from this project being realized or otherwise have ideas on which functionality would be of greatest value.
