District of Columbia Open Data vs Open Government, Belgium

Open Data DC is the District of Columbia government's catalogue of public datasets, spanning crime incidents, GIS/mapping layers, and financial and demographic data, published on an Esri ArcGIS Hub site. Datasets are queryable keyless through the Hub's search and DCAT feed APIs and through individual ArcGIS Feature/Map Services, returning JSON, GeoJSON, CSV, or shapefile depending on the layer. No account or API key is required to read 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.
