cdp-scrapers is a collection of utilities and in-progress or actively maintained CDP instance event scrapers. The purpose of this library is to help new CDP instance maintainers have a quick plethora of examples for getting started on developing their event scraper functions.

General Legistar utility functions.

from cdp_scrapers.legistar_utils import get_legistar_events_for_timespan
from cdp_scrapers.instances import get_seattle_events
from datetime import datetime

# Get all events (and minutes item and voting details)
# for a provided timespan for a legistar client
# Returns List[Dict]
seattle_legistar_events = get_legistar_events_for_timespan(
    client="seattle",
    timezone="America/Los_Angeles",
    start=datetime(2021, 7, 12),
    end=datetime(2021, 7, 14),
)

# Or parse and convert to CDP EventIngestionModel
seattle_cdp_parsed_events = get_seattle_events(
    from_dt=datetime(2021, 7, 12),
    to_dt=datetime(2021, 7, 14),
)

Our current event scraper structure is as follows. The main function get_events gets all the required data and it calls the get_content_uris function to return the required video data.

If your city uses Legistar and the Legistar data is publicly available.

• You may be able to reuse our scraper with minimal modifications, such as providing the correct Legistar client ID for your municipality.
• If the Legistar data returned only does not include the EventVideoPath field for the Session.video_uri data, you will only need to implement get_content_uris.

If your city does not use Legistar.

• You will need to build your own event scraper.

Example of a completed scraper: cdp_scrapers.instances.seattle.SeattleScraper

For more details about creating a custom scraper for your municipality's Legistar data, please visit here.

If you would like to deploy a CDP instance or would like to use this library as a method for retrieving formatted legislative data, please feel free to contribute a new custom municipality scraper!

If it isn't possible to use our generalized Legistar tooling to write your scraper, you will need to create your own event scraper to proceed with the deployment.

1. Please see our documentation on the minimum data required for CDP event ingestion to understand what data your scraper should return.

2. From there, begin with our empty custom scraper function template and fill in your scraper.

3. After your scraper is completed, you can create a pull request to add your scraper into the cdp-scrapers repo so it can be added into the final repo for your CDP instance.

4. Our automated action will run your scraper to verify it returns the correct data. If it is successful, you may proceed to the next deployment step. If not, we will automatically share the error message so you can fix the issue and the scraper can be tested again afterwards.
