This deliverable describes how to manage metagenomics data in the HEAP technical platform. It provides the data model representing semantics to access metadata about metagenomics experiments. The model provides the necessary components to cover the data cycle from samples to analysis results. The HEAP metagenomics data model follows the omics metadata model from the EHEN Metadata Working Group, subgroup: omics. This deliverable also describes the metagenomics pipelines implemented in the HEAP platform available to the researchers from HEAP and EHEN.
