Several tools for bulk data import into Wikibase were reviewed and categorized by their approach: API wrappers, scripts interacting with the database, and direct database access. These tools were compared on usability and performance, using benchmarks provided by their developers. The review also highlighted the lack of native API support for bulk import functionality. Most tools function as workarounds, emphasizing the limitations of the current API. The ideal solution would combine the high performance of direct database access with the Wikibase integration and features provided by the API.
These findings were shared with product for feedback. We also consulted with user research and colleagues who worked on the REST API, which led us to prioritize further research into extending the API with a bulk import method or implementing a CLI tool as a potential solution.
