Intro

Italy is introducing a new API Ecosystem because the complexity of the old SOAP-based protocol was now a barrier for the creation of newer services.

This talk presents the Digital Transformation Team ongoing work on an interoperability framework based on (REST) API, including:

• the scheme standardization based on EU standards, ontologies and RFC
• an availability strategy based on a distributed circuit-breaker and throttling patterns
• a contract-first (API-first) approach to REST services via OpenAPI spec

Challenges

• when you can replace SOAP Headers with the HTTP semantics introduced in RFC 7230-7238
• strategies for a non-repudiation system based on HTTP (eg. DOSETA, JWS, ..)
• the path towards an European interoperable API Ecosystem

Prerequisites

• basic knowledge of SOAP, REST and the HTTP protocol
• general web service issues, DDOS, availability and metrics
