Open City Data

Socrata provides an API for city open data.

For a dataset such as SF crime, to to the API tab on top right.

That provides you with the dataset identifier.

Use the dataset identifier to grab specific tables for a given city_id (data.sfgov.org) -

E.g., vw6y-z8j6 for SF 311 data.

E.g., tmnf-yvry for SF Police data.

pip install sodapy

from langchain.document_loaders import OpenCityDataLoader

dataset = "vw6y-z8j6"  # 311 data
dataset = "tmnf-yvry"  # crime data
loader = OpenCityDataLoader(city_id="data.sfgov.org", dataset_id=dataset, limit=2000)

docs = loader.load()
