 We opted to maintain these archives with [Git](https://git-scm.com) on [GitHub](https://github.com/poseidon-framework) to ensure clean version management on the file level. The context data in a Poseidon package is text data that can be stored and maintained easily with line-wise version control. Unfortunately that does not hold true for the large genotype data files. They are not suitable to be handled in Git directly. Instead we rely on GitHub's [large file storage system](https://docs.github.com/en/repositories/working-with-files/managing-large-files/about-large-files-on-github), which comes with a number of technical drawbacks both for developers and users of the Poseidon archives.

 ## The Poseidon Community Archive (PCA)

 The Poseidon Community Archive is the oldest and arguably the most important public archive. It stores publication-wise packages, so one package for the genotype data released with one paper.
 
 **The PCA focusses on author submissions**, so Poseidon packages prepared by the authors of the packaged publication, containing exactly the genotype data used for the analysis in the paper. This ensures a high degree of computational reproducibility. Author submissions are also ideal for the context data in the .janno file, because the respective domain-experts are generally most knowledgable on the spatiotemporal origin of their samples.

 ## The Poseidon Minotaur Archive (PMA)

 The Poseidon Minotaur Archive mirrors the PCA in that it features publication-wise packages, sometimes even the very same as the PCA. To distinguish them clearly, package titles and sample-wise Poseidon_IDs in the PMA carry the suffix `_MNT` (for "MiNoTaur").
 
 **Packages in the PMA include consistently reprocessed genotype data**, run through the [Minotaur workflow](minotaur). Consitent bioinformatic processing across publications is an important quality for meta-analysis. So while the context information in the .janno file between PCA and PMA overlaps, the PMA packages are adjusted for data reuse beyond paper-wise reproducibility.

 The Poseidon AADR Archive is the conceptionally most simple archive. It features **"poseidonized" versions of releases of the [Allen Ancient DNA Resource (AADR)](https://reich.hms.harvard.edu/allen-ancient-dna-resource-aadr-downloadable-genotypes-present-day-and-ancient-dna-data)**. The code and decisions for the cleaning and packaging process are documented [here](https://github.com/poseidon-framework/aadr2poseidon). Due to file size limitations of GitHub's LFS system each AADR dataset is split into smaller sub-packages by data type and geographic origin.
