How To

1. Install package

pip install common-data-format-validator

2. Create your own schema

Create your data schema according to the Common Data Format specificiations for any of:

• Offical Match Data
• Meta Data
• Event Data
• Tracking Data
• Skeletal Tracking Data

3. Test your schema

Once you have created your schema, you can check it's validity using the available SchemaValidators for each of the above mentioned data types.

from cdf import (
    TrackingSchemaValidator, 
    MetaSchemaValidator, 
    EventSchemaValidator,
    MatchSchemaValidator    
)

# Example valid tracking data
validator = TrackingSchemaValidator()
validator.validate_schema(
    sample="cdf/files/sample/tracking_v0.2.0.jsonl"
)

---

Note

The validator checks:

• All mandatory fields are provided
• Snake case is adhered for each key and for values (except for player names, city names, venue names etc.)
• Data types are correct (e.g. boolean, integer etc.)
• Value entries for specific fields are correct (e.g. period type can only be one of 5 values)
• Position groups and positions follow naming conventions in CDF Appendix C Figure 7

The validator (currently) does not check:

• British spelling
• Correct pitch dimensions
• Color codes are hex (e.g. #FFC107)
• If player_ids (or other ids) in meta are in tracking, event etc. or vice versa
• Position labels fit within the formation specifications
