MARS: Multi-omics Adapter for Repository Submissions

MARS is a framework for submitting multi-omics life-science studies to multiple target repositories using the ISA-JSON metadata standard.

Full documentation and concepts are hosted on the MARS website: https://elixir-europe.github.io/MARS/

Key components

ISA-JSON in MARS

• How MARS uses ISA-JSON for multi-omics metadata exchange: https://elixir-europe.github.io/MARS/#isa-json-as-metadata-carrier
• Human readable presentation of the MARS ISA-JSON schema: https://elixir-europe.github.io/MARS/mars-isa-json

Stakeholders

• End-users, ISA-JSON–producing platforms, data brokers, and repositories: https://elixir-europe.github.io/MARS/stakeholders

Repository API (Adapters)

• Standard for programmatic ISA-JSON ingestion and receipt generation: https://elixir-europe.github.io/MARS/repository-services/repository-api
• Java utilities—including the standard receipt model—for developers building MARS-compatible repository adapters: https://github.com/elixir-europe/mars-repository-lib

MARS-cli

• Python command-line tool and library for multi omics ISA-JSON submissionsubmissions to multiple repositories: https://github.com/elixir-europe/mars-cli
