$ pip install .

Usage

Convention GeoJSON CSB 3.1

JSON files conforming to GeoJSON CSB 3.0.0 metadata can be validated using the 3.1.0-2023-03 schema (e.g., convention 'GeoJSON CSB 3.1'):

$ csbschema validate -f docs/IHO/b12_v3_1_0_example.json
CSB data file 'docs/IHO/b12_v3_1_0_example.json' successfully validated against schema '3.1.0-2023-03'.

Validating an invalid document will show where in the document errors were be found:

$ csbschema validate -f docs/IHO/b12_v3_1_0_example-invalid.json 
Validation of docs/IHO/b12_v3_1_0_example-invalid.json against schema 3.1.0-2023-03 failed due to the following errors: 
Path: /properties/trustedNode/convention, error: 'GeoJSON CSB 3.0' is not one of ['GeoJSON CSB 3.1']
Path: /features/1/properties, error: 'depth' is a required property
Path: /features/3/properties, error: 'time' is a required property

Path: /properties/platform/IDNumber, error: IDNumber IMO3699580 is not valid for IDType MMSI.

Conventions GeoJSON CSB 3.0 and XYZ CSB 3.0

A schema for the provisional JSON encoding of B12 3.0.0 data and metadata (e.g., convention 'GeoJSON CSB 3.0') is available under the schema name '3.0.0-2023-03':

$ csbschema validate -f docs/NOAA/example_csb_geojson_file.geojson --version 3.0.0-2023-03

Similarly, a metadata-only schema (e.g., convention 'XYZ CSB 3.0') is available under the schema name 'XYZ-3.0.0-2023-03':

$ csbschema validate -f docs/NOAA/noaa_b12_v3_0_0_xyz_required.json --version XYZ-3.0.0-2023-03

The metadata-only 'XYZ schema' is meant to be used for JSON metadata supplied alongside CSB data in CSV or another format.

Convention GeoJSON CSB 3.2

A schema for a beta JSON encoding of B12 3.0.0 (e.g., convention 'GeoJSON CSB 3.2') is available under the schema name '3.2.0-BETA':

$ csbschema validate -f docs/IHO/b12_v3_2_0-BETA_example.json --version 3.2.0-BETA
CSB data file 'docs/IHO/b12_v3_2_0-BETA_example.json' successfully validated against schema '3.2.0-BETA'.

Run csbschema validate --help for more information about validating against different versions of the schema.

Testing

First, install csbschema with test dependencies:

$ pip install ".[test]"

Then run unit tests:

$ pytest tests/unit/test_*.py

Run integration tests, which tests running the csbschema validate command line tool for many of the example CSB documents found in the csbschema repository:

$ bash tests/integration/validate_cmd.sh
