The 20.4 billion triples in LinkedTCGA remedy these problems by being a five-star Linked Data representation of the data made publicly available by TCGA. Researchers now need solely a small set of SPARQL queries to gather data represented in a standard format (RDF). Linked TCGA publishes different types of data (clinical, exon, methylation, miRNA etc.). The data to each tumor is have distributed into 3 different SPARQL endpoints. The federated query engine is powered by TopFed, a dedicated engine for the TCGA data that was shown to outperform state-of-the-art approaches significantly (see publications). More information on the LinkedTCGA data can be found on the project website.
