D3fend Mitigation JSON Schema Error

[0xm00n]

When setting up BRON through docker, I repeatedly get this JSON schema error. This does not seem to be a local environment issue.

'D3A-AAD' does not match 'D3-[A-Z]+'

Failed validating 'pattern' in schema['properties']['original_id']:
    {'description': 'ID from MITRE D3FEND. E.g. '
                    "'ActiveCertificateAnalysis'. TODO pattern",
     'pattern': 'D3-[A-Z]+',
     'type': 'string'}

On instance['original_id']:
    'D3A-AAD'

Thank you bringing it to our attention. Looks like there have been changes to the possible D3fend id patterns.

A quick fix could be to change the jsonschema pattern to allow for D3 and D3A e.g. D3?-[A-Z]+ on

BRON/graph_db/schemas/d3fend_mitigation_schema.json

Line 15 in 4298a11

"pattern": "D3-[A-Z]+"

We will get a fix out for this.

Hi, I tested out building BRON locally on Ubuntu and the correct jsonschema pattern is D3[A-Z]?-[A-Z]+ which allows BRON to fully build.

Thanks! I patched the schema.
