AboutSupportDeveloper GuideVersion 38.126.83.79

Extends an AppIdentifier, describing an application or instance of an application, with additional descriptive metadata that is usually provided by an FDC3 App Directory that the desktop agent connects to.

The additional information from an app directory can aid in rendering UI elements, such as a launcher menu or resolver UI. This includes a title, description, tooltip and icon and screenshot URLs.

Note that as AppMetadata instances are also AppIdentifiers they may be passed to the app argument of fdc3.open, fdc3.raiseIntent etc.

interface AppMetadata {
    appId: string;
    description?: string;
    icons?: Icon[];
    instanceId?: string;
    instanceMetadata?: Record<string, any>;
    name?: string;
    resultType?: null | string;
    screenshots?: Image[];
    title?: string;
    tooltip?: string;
    version?: string;
}

name?: string

The 'friendly' app name. This field was used with the open and raiseIntent calls in FDC3 <2.0, which now require an AppIdentifier wth appId set. Note that for display purposes the title field should be used, if set, in preference to this field.

resultType?: null | string

The type of output returned for any intent specified during resolution. May express a particular context type (e.g. "fdc3.instrument"), channel (e.g. "channel") or a channel that will receive a specified type (e.g. "channel<fdc3.instrument>").
