Colorado Information Marketplace vs Open Government, ACT

The Colorado Information Marketplace is the state's open-data portal, built on the Socrata platform and covering budget, transportation, public-safety, and demographic datasets from Colorado agencies. Every dataset is queryable through Socrata's SODA REST API without an account, with an optional free app token only needed to raise the anonymous rate limit. Results are returned as JSON by default, with CSV and XML also available per dataset.

Data.act.gov.au is the Australian Capital Territory's open-data portal, run on Socrata; its catalog discovery API at `www.data.act.gov.au/api/catalog/v1` answers keyless GETs with full dataset JSON and a wildcard `Access-Control-Allow-Origin` header (the bare `data.act.gov.au` apex briefly redirects through plain HTTP before landing back on the `www` host over HTTPS, so link to `www` directly). Individual datasets are queryable through Socrata's SODA API in JSON or CSV, covering ACT government services, planning, and community data.
