In the following issue #671 we discussed the major changes for SDRF specification during the next release 1.1. One of them, is the extension of SDRF for metabolomics.

GOAL: The aim of adapting SDRF to metabolomics is to use the same format in multiomics experiments for reanalysis and data integration. The format do not aim to replace other standards in the field like ISA-TAB but complement them, to allow in the future easy integration across different omics repositories and pipelines.

The steps for this development would be:

• Make a proposal to the specification of how to represent metabolomics data into SDRF.
• Write a set of examples that represent metabolomics data into SDRF.
• Get feedback from the community using PR comments and meeting with EUBIC members.
• Adapt the SDRF validator sdrf-pipelines.
• Accept the proposal for the specification.
• Implement a converter on sdrf-pipelines to transform ISA-TAB files into SDRF.
• Convert other popular database metabolomics data into SDRF.

These efforts will be led by @mmattano @nilshoffmann @ypriverol
