[SCHEMA] BEP017

[rwblair]

Schematization attempt based on google doc of BEP017.

Todo:

objects/metadata.yaml

The following entries still need to be added:

• AdditionalMatrixDimensions
• AdditionalMatrixDimensionDescription
• AdditionalMatrixDimensionsUnits
• MeasureDescription
• MeasurePoint
• MeasureUnits
• NodeIndicesFile
• Serialization

These may be need unique entries or could use built in ones:

• Description
• Sources

Axes Definition needs to be completed:

• schema for objects in array

NodeFiles in google doc is either a uri or a list of uris. I defined it only as an array of uris.

• Is that ok?
• Should this be a bids-uri?

Every description needs to be filled in:

• Replace every Todo I left in descriptions.

objects/columns.yaml

Fill in descriptions:

• matrix_index
• node_file
• node_index

node_file example uses labels for atlas- entities. Should it be the full filename? Or should the shorthand name be defined in the _relmat.json NodeFiles entry?

rules/tabular_data/derivatives/relmat.yaml

• Does *_relmat.tsv need an entry here?
• Confirm nodeindices entry.

rules/sidecars/derivatives/relmat.yaml

• Review requirement levels
• Enforce Serialization level_addendum
• nodeindices.json Looks to be only fields describing columns. Do we need this? Are there any metadata fields missing?

rules/checks/derivatives/relmat.yaml

• Does not currently exist. What requirements in the BEP not covered in metadata and tsv need to be enforced here?

rules/files/derivatives/relmat.yaml

• datatypes currently listed as any which isn't valid. Should there be a wildcard datatype? Or should this be filled in explicitly?

meta/associations.yaml

• Does _relmat.* need _nodeindices.tsv in its associations for any checks?
• Does _nodeindices.tsv need _relmat.json in its associations for any checks?

Hi @rwblair,

thanks so much for starting to work on this!
As I'm not super familiar with the schema and the approach here, I wanted to ask how I should provide feedback/help out?
I could, for example, answer some of the questions you raised here.

Best, Peer
