Adding NIDM to Neuroshapes

[taylormacmillan]

For anyone not familiar with NIDM (Neuroimaging Data Model), it is being developed by INCF-NIDASH, and consists of a collection of documents that use PROV as a basis for describing information related to neuroimaging studies.

At the Krembil Centre for Neuroinformatics we have been working on creating a SHACL schema that validates a NIDM Experiment document. We have one version that validates the structure specifically, ensuring that each PROV entity and activity is correctly defined. We have also created a version that constrains the content of the NIDM document in addition to structure, such as limiting the allowable value ranges for attributes within an entity (ex. EchoTime). Currently, the value ranges given within that schema are just provided as examples.

We think incorporating these schemas into Neuroshapes would be beneficial, providing the addition of a validatable data model for neuroimaging. A pull request has been created to add these schemas.
