Inspired by the work of JSON for Linked Data and Schema.org we build a Schema for insurances (also called Schema4i or in short S4I). As a shared vocabulary Schema4i.org is the first semantic data model for insurances in the world that makes it easier for API developers and website operators to get the maximum benefit from data. The data model is open and free for use. It might be used especially in the insurance industry or beyond. You can use it to provide awesome semantic APIs and websites with insurance-related meaning for better networking with other participants in the industry across all borders. Why? Because in the future everything's driven by Linked Data.
