This step reads all valid items from a specified file representing a local repository storing incremental changes for database identification keys. This file is located in the repository's directory and is named "repos_data.cif" (or "data.cif" for DQC version 2 (then known as Purity)). The output column keyColumn contains the pairing-key values that were assigned when the repository was created.

By using classes cz.adastra.cif.tasks.identify.[ver].repository.read.RepositoryReader it is possible to read the repository format of previous DQC versions {v2, v3, v35, etc.}.
