The document discusses two open data platforms - the Open Data Platform and Open Sensor Networks Platform. The Open Data Platform includes an open data portal, open data registry, linked data store, and data enrichment tools. It allows cities to publish and store open data and link datasets. The Open Sensor Networks Platform includes a core system linked to an open data registry to deliver sensor data via standard formats. It also includes a high-speed database for sensor measurements and REST APIs. The document provides an overview of these platforms and their components for publishing, storing, and accessing open city data.
