. . . . "An experimental sandbox for designing and testing nanopublication templates for provenance research.\r\n\r\nThis space enables the structured modeling of provenance information—such as ownership histories and attribution claims—as formal, citable nanopublications. It supports iterative experimentation with template structures, data modeling approaches, and the representation of uncertainty and multi-source evidence." . "2027-05-06T18:00:00.0+01:00"^^ .
