Checklist to complete before beginning development

No development should be done on a Provider API Script until the following info is gathered:

• Verify there is a way to retrieve the entire relevant portion of the provider's collection in a systematic way via their API.
• Verify the API provides license info (license type and version; license URL provides both, and is preferred)
• Verify the API provides stable direct links to individual works.
• Verify the API provides a stable landing page URL to individual works.
• Note other info the API provides, such as thumbnails, dimensions, attribution info (required if non-CC0 licenses will be kept), title, description, other meta data, tags, etc.
• Attach example responses to API queries that have the relevant info.

General Recommendations for implementation

• The script should be in the src/cc_catalog_airflow/dags/provider_api_scripts/ directory.
• The script should have a test suite in the same directory.
• The script must use the ImageStore class (Import this from
  src/cc_catalog_airflow/dags/provider_api_scripts/common/storage/image.py).
• The script should use the DelayedRequester class (Import this from
  src/cc_catalog_airflow/dags/provider_api_scripts/common/requester.py).
• The script must not use anything from
  src/cc_catalog_airflow/dags/provider_api_scripts/modules/etlMods.py, since
  that module is deprecated.
• If the provider API has can be queried by 'upload date' or something similar,
  the script should take a --date parameter when run as a script, giving the
  date for which we should collect images. The form should be YYYY-MM-DD (so,
  the script can be run via python my_favorite_provider.py --date 2018-01-01).
• The script must provide a main function that takes the same parameters as from
  the CLI. In our example from above, we'd then have a main function
  my_favorite_provider.main(date). The main should do the same thing calling
  from the CLI would do.
• The script must conform to PEP8. Please use pycodestyle (available via
  pip install pycodestyle) to check for compliance.
• The script should use small, testable functions.
• The test suite for the script may break PEP8 rules regarding long lines where
  appropriate (e.g., long strings for testing).

Examples of other Provider API Scripts

For example Provider API Scripts and accompanying test suites, please see

• src/cc_catalog_airflow/dags/provider_api_scripts/flickr.py and
• src/cc_catalog_airflow/dags/provider_api_scripts/test_flickr.py, or
• src/cc_catalog_airflow/dags/provider_api_scripts/wikimedia_commons.py and
• src/cc_catalog_airflow/dags/provider_api_scripts/test_wikimedia_commons.py.

@mathemancer As mentioned in #520 I will begin work on this.
Thank You!

[dravadhis]

@mathemancer I am working on issue on issue #521. The API requires OAuth 1.0 authorisation via an api_key and consumer_secret. To send an authorised request I need to use a library called requests-oauthlib (See here for reference). Should I add this library in the requirements file? Or is there any other way to go about this?

[mathemancer]

@dravadhis I think that should be fine. Just add it to both requirements files (make sure to freeze the version in prod requirements, but not dev).
