are distributed under CC-BY-SA 4.0. This defines the license for the
whole dataset, which also contains non-copyrighted bibliographic
metadata and reference data derived from I4OC (CC0). Note that the API
only provides a subset of the data in the zbMATH Open Web interface. In
several cases, third-party information, such as abstracts, cannot be
made available under a suitable license through the API. In those cases,
we replaced the data with the string 'zbMATH Open Web Interface contents
