discussion of cloning studies

[jdkent]

fundamental question:
How should clones be related to the study they are cloned from?

option 1: source/source_id parameter (current solution)

option 2: create new table for clones and relate them to original studies

option 3: use parent hash with cloned study to indicate versions

open questions:

• should you be able to rename a cloned study?
• how should page_size and ordering work when listing studies and clones?

[jdkent]

when cloning/ingesting from external sources (neurovault) maybe do not use source/source_id, but use external_id or something like that.

[jdkent]

current working plan:

• add unique parameter to studies endpoint to filter out cloned studies
• add parameter (parent_id) to separate the notion of cloning versus ingesting from an external source
