FDC3

aid: fdc3
name: FDC3
description: 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.

  name: FDC3 Desktop Agent API
  description: The FDC3 Desktop Agent API is the primary interface for application interoperability on the financial desktop.
    It provides a JavaScript/TypeScript API that applications use to open other applications, raise intents to request functionality
    from peer apps, broadcast typed context data on channels, listen for incoming context and intents, discover available
    applications and their capabilities, and create private two-party communication channels. Desktop Agents implement this
    API and expose it to the applications they host.

  name: FDC3 App Directory API
  description: The FDC3 App Directory (AppD) is a REST API standard for registering and discovering financial desktop applications.
    Desktop Agents query App Directories to resolve application definitions when launching apps or resolving intents. The
    v2 endpoints are the current standard, supporting retrieval of all app definitions and lookup by appId. Authentication
    is supported via HTTP Authorization Bearer JWT tokens. Implementations are provided by vendors and financial institutions;
    FINOS publishes the specification and JSON schema.

- aid: fdc3:context-data
  name: FDC3 Context Data
  description: FDC3 Context Data defines a standard set of typed data structures used to carry information between financial
    applications when broadcasting or raising intents. Context types include instruments, positions, portfolios, contacts,
    organizations, orders, charts, country, currency, date range, email, and more. Each context type has a JSON schema definition.
    Applications share and receive these typed objects through the Desktop Agent API channels and intent resolution, enabling
    interoperability without custom data mapping.

- aid: fdc3:intents
  name: FDC3 Intents
  description: FDC3 Intents are standardized verbs that applications use to request functionality from other applications
    on the financial desktop. Standard intents include ViewChart, ViewQuote, ViewNews, ViewAnalysis, ViewInstrument, ViewHoldings,
    ViewOrders, ViewResearch, ViewProfile, ViewInteractions, ViewMessages, ViewChat, StartCall, StartChat, StartEmail, CreateInteraction,
    and CreateOrUpdateProfile. Applications declare which intents they handle in their App Directory entry, and the Desktop
    Agent routes intent requests to appropriate handler apps.

- aid: fdc3:desktop-agent-bridging
  name: FDC3 Desktop Agent Bridging
  description: FDC3 Desktop Agent Bridging (DAB) is a wire protocol that enables multiple Desktop Agent implementations to
    interoperate, allowing applications running under different Desktop Agents to share context and raise intents with each
    other. The bridging specification defines a WebSocket-based protocol for agent-to-agent communication, enabling cross-agent
    context broadcasting and cross-agent intent resolution within the same desktop environment or across network boundaries.
