Do we have to expose different parts of the data model structure at different points in the workflow? Superseded: decisions in [ADR 2](./0002-use-a-common-data-model) (use JSON-LD) and [ADR 11](./0011-record-provenance-of-metadata) (create a unified data model of metadata and provenance) will result in a context [DAO](https://en.wikipedia.org/wiki/Data_access_object) from beginning till end of a run. ## Decision Drivers * Different data need to be available at different points * Convention over configuration ## Considered Options * Complete I/O * Restricted I/O ## Decision Outcome Chosen option: "", because comes out best. ## Pros and Cons of the Options ### Complete I/O E.g., with pre-filled contents
