An online network for sharing somatic cancer genomic and clinical data from around the world, making the data accessible for research use in real time. CGTD provides a basic HTML interface and RESTful API to add, list and authenticate submissions as well as the peering relationship between stewards. Submissions consist of a JSON manifest with a list of fields and files. Fields typically include de-identified clinical data (i.e. tumor type). Files typically consist of somatic variant vcf files and gene expression tsv file. Manifest's and files are stored and referenced by the multihash of their content.
