Metadata schema update: allow an array of experiment accessions; biosample accessions

[ami-day]

For which schema is a change/update being suggested?

cell_suspension

What should the change/update be?

Allow an array of experiment accessions, biosample accessions and insdc sample accessions to be entered in the following fields in the cell_suspension tab:

process.insdc_experiment.insdc_experiment_accession
cell_suspension.biomaterial_core.biosamples_accession
cell_suspension.biomaterial_core.insdc_sample_accession

Currently only a single accession is accepted (string).

This update constitutes a minor change to the schema(s) it affects.

What new field(s) need to be changed/added?

process.insdc_experiment.insdc_experiment_accession
cell_suspension.biomaterial_core.biosamples_accession
cell_suspension.biomaterial_core.insdc_sample_accession

from enum: string to enum: array

Why is the change requested?

It is necessary for experimental designs where the same cell suspension is subjected multiple library preparation types (e.g. 1 cell suspension -> gex, vdj, vdj Ig libraries).
