Dashed lines: mapping of metadata standards, links to aggregators, data Aggregators: repositories or various indices Data: digital research objects

Pilot projects* Core development team

* There is work for everyone (and more)

Designed as an element of the ecosystem!

Use cases- community-driven effort!

The ‘right’ level of metadata elements!!

Examples of competency questions, derived from the use cases

The ‘appropriate’ metadata standards!!

Mapping the landscape of standards and databases in the life sciences

mapped a variety of metadata standards and database schemas

Generic schemas:!•  schema.org!•  DataCite!•  RIF-CS!•  DCAT!•  PROV!•  VOID!•  Dublin Core !•  etc…!!

Life/biomedical schemas:!•  BioProject!•  BioSample!•  MiNIML!•  PRIDE-ml!•  GA4GH metadata schema!•  SRA xml!•  CDISC SDM / BRIDGE model !•  etc…!

We have aimed to have maximum coverage of use cases with minimal number of data elements

We do foresee that not all questions can be answered in full
