  "description": "Returns a healthcare directory for a given healthcare organization.  This operation accepts a lastDownloaded field.  Given this date, it returns an organization's entire shareable directory.  This can include Practitioners, PractitionerRoles, Locations, Organizations, HealthCareServices, and Endpoints.  The server can return these resources in any order, and the client must be able to handle that.  References in the bundle must be relative, and the bundle may include duplicative data.   Previous work in this area has been done by the Argonauts, and can be found at: http://build.fhir.org/ig/argonautproject/provider-directory/",
