This milestone report presents version 0.1 of the b3verse, a suite of R packages developed to support biodiversity analysis workflows based on occurrence cubes within the B3 project. The b3verse provides a coherent, modular, and reproducible software ecosystem for data acquisition, cube simulation, processing, indicator calculation, and uncertainty assessment. It is designed for ecological researchers, developers, and policy-oriented users who work with biodiversity data.

The current version of the b3verse includes eleven R packages, available through a dedicated R-universe platform, with individual GitHub repositories for collaborative development and issue tracking. To ensure accessibility and sustainability, snapshot versions are archived on Zenodo. The platform also includes the b3data data package, providing example datasets in the Frictionless Data Package format, directly accessible via R.

This milestone documents:

the current structure and installation of the b3verse;
ongoing development and quality assurance, including code reviews and testing;
future goals, such as migrating additional packages, enhancing tutorials, and broadening the data resource base;
and recommendations for improving usability and reproducibility, focussing on tutorials, unit testing, and formal archiving.
