A command-line interface (CLI) for working with fiboa.

• Getting Started
• Documentation / Commands
• Development

Getting Started

In order to make working with fiboa easier we have developed command-line interface (CLI) tools such as inspection, validation and file format conversions.

Installation

You will need to have Python 3.9 or any later version installed.

Run pip install fiboa-cli in the CLI to install the validator.

Optional: To install additional dependencies for specific converters, you can for example run: pip install fiboa-cli[xyz] with xyz being the converter name.

Note on versions:

• fiboa CLI >= 0.3.0 works with fiboa version > 0.2.0
• fiboa CLI < 0.3.0 works with fiboa version = 0.1.0

Execute a command

After the installation you should be able to run the following command: fiboa

You should see usage instructions and available commands for the CLI.

fiboa CLI supports various commands to work with the files:

Commands

Validation

To validate a fiboa GeoParquet or GeoJSON file, you can for example run:

• GeoJSON: fiboa validate example.json --collection collection.json
• GeoParquet: fiboa validate example.parquet --data

Check fiboa validate --help for more details.

The validator also supports remote files.

• http:// or https://: no further configuration is needed.
• s3://: s3fs needs to be installed (run pip install .[s3]) and you may need to set environment variables. Refer here for how to define credentials.
• gs://: gcsfs needs to be installed (run pip install .[gcs]). By default, gcsfs will attempt to use your default gcloud credentials or, attempt to get credentials from the google metadata service, or fall back to anonymous access.

Create fiboa GeoParquet from GeoJSON

To create a fiboa-compliant GeoParquet for a fiboa-compliant set of GeoJSON files containing Features or FeatureCollections, you can for example run:

• fiboa create-geoparquet geojson/example.json -o example.parquet -c geojson/collection.json

Check fiboa create-geoparquet --help for more details.

Create fiboa GeoJSON from GeoParquet

To create one or multiple fiboa-compliant GeoJSON file(s) for a fiboa-compliant GeoParquet file, you can for example run:

• GeoJSON FeatureCollection: fiboa create-geojson example.parquet -o dest-folder
• GeoJSON Features (with indentation and max. 100 features): fiboa create-geojson example.parquet -o dest-folder -n 100 -i 2 -f

Check fiboa create-geoparquet --help for more details.

Inspect fiboa GeoParquet file

To look into a fiboa GeoParquet file to get a rough understanding of the content, the following can be executed:

• fiboa describe example.parquet

Check fiboa describe --help for more details.

Merge fiboa GeoParquet files

Merges multiple fiboa datasets to a combined fiboa dataset:

• fiboa merge ec_ee.parquet ec_lv.parquet -o merged.parquet -e https://fiboa.github.io/hcat-extension/v0.1.0/schema.yaml -i ec:hcat_name -i ec:hcat_code -i ec:translated_name

Check fiboa merge --help for more details.

Create JSON Schema from fiboa Schema

To create a JSON Schema for a fiboa Schema YAML file, you can for example run:

• fiboa jsonschema example.json --id=https://fiboa.github.io/specification/v0.1.0/geojson/schema.json -o schema.json

Check fiboa jsonschema --help for more details.

Validate a fiboa Schema

To validate a fiboa Schema YAML file, you can for example run:

• fiboa validate-schema schema/schema.yaml

Check fiboa validate-schema --help for more details.

Improve a fiboa Parquet file

Various "improvements" can be applied to a fiboa GeoParquet file. The commands allows to

• change the CRS (--crs)
• change the GeoParquet version (-gp1) and compression (-pc)
• add/fill missing perimeter/area values (-sz)
• fix invalid geometries (-g)
• rename columns (-r)

Example:

• fiboa improve file.parquet -o file2.parquet -g -sz -r old=new -pc zstd

Check fiboa improve --help for more details.

Update an extension template with new names

Once you've created and git cloned a new extension, you can use the CLI to update all template placeholders with proper names.

For example, if your extension is meant to have

• the title "Timestamps Extension",
• the prefix ts (e.g. field ts:created or ts:updated),
• is hosted at https://github.io/fiboa/timestamps-extension (organization: fiboa, repository timestamps-extension),
• and you run fiboa in the folder of the extension.

Then the following command could be used:

• fiboa rename-extension . -t Timestamps -p ts -s timestamps-extension -o fiboa

Check fiboa rename-extension --help for more details.

Converter for existing datasets

The CLI ships various converters for existing datasets.

To get a list of available converters/datasets with title, license, etc. run:

• fiboa converters

Use any of the IDs from the list to convert an existing dataset to fiboa:

• fiboa convert de_nrw

See Implement a converter for details about how to

Development

To install in development mode run pip install -e . in this folder.

For the tests first run pip install -r requirements-dev.txt to install pytest. Then you can run pytest to execute the tests.

Implement a converter

The following high-level description gives an idea how to implement a converter in fiboa CLI:

1. Create a new file in fiboa_cli/datasets based on the template.py
2. Implement the convert() function / test it / run it
3. Add missing dependencies into a separate dependency group in setup.py
4. Add the converter to the list above
5. Create a PR to submit your converter for review
