FDC3 (Financial Desktop Connectivity and Collaboration Consortium) is an open standard hosted by FINOS for interoperability between financial desktop applications. The standard defines how applications launch other apps, share typed context data, raise and resolve intents across the financial desktop, and register themselves in an App Directory. FDC3 eliminates the need for custom bilateral agreements between software vendors and enables plug-and-play integration workflows for financial services firms. Current version is 2.2, licensed under the Community Specification License 1.0 with code released under Apache 2.0.
