English: Wikidata, the open knowledge graph sister to Wikipedia, is undergoing major changes in 2025 as the Wikimedia Foundation splits its data into two graphs. One of the split pieces is essentially the data of the WikiCite project, which is an initiative expanding the use of Wikidata as a platform for scholarly information. Due to WikiCite’s success, it accounts for over 50% of the triples on the Wikidata graph. This split was motivated by challenges in scaling up the Wikidata SPARQL Query Service, which relies on Blazegraph, a technology unsuited for Wikidata’s current scale and growth rate. While the split has been prepared since 2021, this large infrastructure change has wide implications both for community tools which use WikiCite data, such as the Scholia platform, as well as for core functionalities of Wikidata, such as systems that detect duplicate items and constraint violations. In this paper, we present an overview of the infrastructure available on Wikidata for querying scholarly information and how it serves the community endeavours related to the WikiCite initiative. In particular, we focus on the Wikidata Query Service split, its motivations, and its impacts for those intending to use Wikidata as a source of semantic scholarly data. We present the alternatives for rewriting or redirecting broken queries, making explicit the rules of the graph split, and when federated queries are now required, guiding stakeholders on how to adapt to the new infrastructure.
