The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

we provide a processed OpenAIRE graph which is downscaled to 16 GB RAM, while preserving the full graph structure

C2weakest assumption

That the chosen compact representation and simple format retain all information needed for the majority of downstream citation-graph analyses without introducing hidden losses or requiring users to re-derive missing fields.

C3one line summary

A 16 GB version of the complete OpenAIRE citation graph is released together with processing code, keeping every node and edge while fitting on ordinary machines.
