The Maven Central 2022 Dataset

We present the Maven Central 2022 Dataset (MC22), based on a snapshot of Maven Central dated April
4, 2022, for our replication study and future scientific work.

The dataset contains metadata on jars in Maven Central and evolution metrics on syntactically SemVer-adhering
artifacts. It can be used to answer questions like: How often and when are updates of existing components
published? How do version tags look like and how do their syntactical forms change over time? How
common is the use of deprecation tags? and many more.

The dataset contains three groups of information: Metadata on all jars in the snapshot, metrics on an-
alyzed upgrades and metrics on analyzed components. The metrics are calculated seperately regarding
three types of elements: public classes, public methods and protected methods.
