Colorado Information Marketplace vs Open Government, Belgium

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.gov.be is Belgium's federal open-data portal, built on a custom Drupal-based platform rather than CKAN. Rather than a search REST API, it publishes its full catalogue as a DCAT-AP metadata export (RDF/XML and N-Triples) and exposes it live through a Triple Pattern Fragments / Linked Data Fragments server at `ldf.belgif.be/datagovbe`, which answers unauthenticated with a wildcard CORS header. The main site itself also sits behind bot-detection middleware that can block naive scripted fetches, but the LDF endpoint and the documented DCAT export are both reachable directly.
