Interface Asset - Flickr

    Description

    The Flickr Interface Asset (IA) is an "off-the-shelf" component of IntuiFace enabling users to search, browse and manipulate images served by the media hosting Flickr Web service.

    This IA is based on Flickr's public Web Service API.

    IMPORTANT NOTE

    To be able to invoke the Flickr API, you need to register and apply for a free API key here. Once you have your API key, you must enter it in the Set API Key property of the Flickr IA (see screenshot below):

    Any IntuiFace user can modify the visual representation of the Flickr IA. This visual representation - specified by a data template - can access and manipulate any of the properties listed later in this article.
