This dataset was set up as part of our research titled "Formal Specifications Investigated: A Classification and Analysis of Annotations for Deductive Verifiers".
It contains a large set of annotations that were classified according to our taxonomy. We also include the information we used to calculate the confidence intervals that are reported in the paper in Section 4.

The annotations were extracted from examples and case studies for the tools KeY, Krakatoa, OpenJML, VerCors and Verifast. We have included the 10 examples per tool (case studies are not included) from which these annotations have been extracted in These are not licensed under the CC BY 4.0 but under their original licenses. These licenses have been included.
