EPA vs Open Government, Belgium

EPA's Envirofacts platform exposes the agency's environmental compliance and monitoring databases — air quality, drinking water systems, the Toxics Release Inventory, hazardous waste, and Superfund sites — through a keyless REST API at `data.epa.gov/efservice`. Any of the underlying tables can be queried by building a URL from the table name, filter columns, and an output format, with results returned as JSON, XML, CSV, or Excel. EPA's Developer Central site separately documents smaller topic widgets built on the same data.

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.
