Versions:
ArcCommander 1.0.0.0, released by DataPLANT, is a Windows-based command-line utility designed to create, validate, and synchronize Annotated Research Contexts (ARCs)—structured, FAIR-compliant repositories that package data, metadata, code, and workflows for reproducible life-science research. By offering a unified set of sub-commands for initialization, dataset registration, assay annotation, and remote syncing, the software enables researchers to convert loosely organized project folders into self-describing ARC objects ready for local versioning or submission to public repositories such as DataPLANT’s own DataHUB. Typical use cases include converting an existing wet-lab or computational study into an ARC, batch-applying standard ontologies to large assay tables, cloning collaborative ARCs from a Git backend, validating ISA-compliant metadata before peer review, and automating continuous integration pipelines that test whether an ARC still reproduces published results. Because every change is tracked with embedded Git semantics, entire project histories remain auditable while files can be selectively shared through branch-based access control. The lightweight executable runs on any 64-bit Windows 10/11 workstation, integrates with PowerShell or CMD, and accepts JSON/YAML configuration files so that institutional consortia can enforce uniform annotation rules across dozens of parallel studies. Although only one public version (1.0.0.0) has been published to date, its open architecture anticipates semantic-versioned updates that will extend support for additional domain-specific ontologies and cloud storage adapters. ArcCommander is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always providing the newest release and enabling batch installation alongside other applications.
