The document describes a mobile application called Citylive Community Services Platform created for the Brussels regional government. The goals were to reinforce the local economy by creating a digital community and eventually monetize services. Key features included working offline, automatic updates, easy distribution via SMS, website integration, and compatibility with 80% of mobile phones. The technical solution used a SOA architecture with .NET, WCF web services, and Hydra software to provide services and handle authentication, authorization, and data storage. Challenges included the need to extensively test mockups, focus on specific functions rather than large scopes, leverage the internet's open standards, and design for multiple platforms rather than a single one.
