datapackage-registry-py
A Python library for working with a Data Package Registry.
It comes with a cached version of the registry and schemas from https://github.com/dataprotocols/schemas.
Usage
import datapackage_registry
# get the default registry objects
registry = datapackage_registry.Registry()
# see the available profiles in the registry
print(registry.available_profiles)
# {
# 'base': {
# 'id': 'base',
# 'schema': 'https://rawgit.com/dataprotocols/schemas/master/data-package.json',
# 'specification': 'http://dataprotocols.org/data-packages',
# 'title': 'Data Package'
# },
# 'tabular': {
# 'id': 'tabular',
# 'schema': 'https://rawgit.com/dataprotocols/schemas/master/tabular-data-package.json',
# 'specification': 'http://dataprotocols.org/tabular-data-package/',
# 'title': 'Tabular Data Package'
# }
# }
# get a profile by its id
base_profile = registry.get('base')If you’d like to use a custom registry, you can pass its URL or local
path to the Registry() constructor, as in:
import datapackage_registry
registry = datapackage_registry.Registry('http://someplace.com/my-registry.csv')If you’d like to get a schema that's not in the registry, you can pass its URL
or local path to Registry().get_external() method, as in:
import datapackage_registry
registry = datapackage_registry.Registry()
try:
schema = registry.get_external('http://someplace.com/schema.json')
except datapackage_registry.exceptions.DataPackageRegistryException:
pass # handle errorDeveloper notes
These notes are intended to help people that want to contribute to this package itself. If you just want to use it, you can safely ignore this.
Updating the local schemas cache
We cache the schemas from https://github.com/dataprotocols/schemas using git-subtree. To update it, use:
git subtree pull --prefix datapackage_registry/schemas https://github.com/dataprotocols/schemas.git master --squash
