    \brief The Place type represents a location that is a position of interest.

    The Place type represents a physical location with additional metadata describing that
    location.  Contrasted with \l Location, \l Address, and
    \l {coordinate} type which are used to describe where a location is.
    The basic properties of a Place are its \l name and \l location.

    Place objects are typically obtained from a search model and will generally only have their
    basic properties set. The \l detailsFetched property can be used to test if further property
    values need to be fetched from the \l Plugin. This can be done by invoking the \l getDetails()
    method.  Progress of the fetching operation can be monitored with the \l status property, which
    will be set to Place.Fetching when the details are being fetched.

    The Place type has many properties holding information about the location. Details on how to
    contact the place are available from the \l contactDetails property.  Convenience properties
    for obtaining the primary \l {primaryPhone}{phone}, \l {primaryFax}{fax},
    \l {primaryEmail}{email} and \l {primaryWebsite}{website} are also available.

    Each place is assigned zero or more \l categories.  Categories are typically used when
    searching for a particular kind of place, such as a restaurant or hotel.  Some places have a
    \l ratings object, which gives an indication of the quality of the place.

    Place metadata is provided by a \l supplier who may require that an \l attribution message be
    displayed to the user when the place details are viewed.

    Places have an associated \l icon which can be used to represent a place on a map or to
    decorate a delegate in a view.

    Places may have additional rich content associated with them.  The currently supported rich
    content include editorial descriptions, reviews and images.  These are exposed as a set of
    models for retrieving the content.  Editorial descriptions of the place are available from the
    \l editorialModel property.  Reviews of the place are available from the \l reviewModel
    property.  A gallery of pictures of the place can be accessed using the \l imageModel property.

    Places may have additional attributes which are not covered in the formal API.  The
    \l extendedAttributes property provides access to these.  The type of extended attributes
    available is specific to each \l Plugin.

    A Place is almost always tied to a \l plugin.  The \l plugin property must be set before it is
    possible to call \l save(), \l remove() or \l getDetails().  The \l reviewModel, \l imageModel
    and \l editorialModel are only valid then the \l plugin property is set.

    \section2 Saving a Place

    If the \l Plugin supports it, the Place type can be used to save a place.  First create a new
    Place and set its properties:

    \snippet declarative/places.qml Place savePlace def

    Then invoke the \l save() method:

    \snippet declarative/places.qml Place savePlace

    The \l status property will change to Place.Saving and then to Place.Ready if the save was
    successful or to Place.Error if an error occurs.

    If the \l placeId property is set, the backend will update an existing place otherwise it will
    create a new place.  On success the \l placeId property will be updated with the identifier of the newly
    saved place.

    \section3 Caveats
    \input place-caveats.qdocinc

    \section3 Saving Between Plugins
    When saving places between plugins, there are a few things to be aware of.
    Some fields of a place such as the id, categories and icons are plugin specific entities. For example
    the categories in one manager may not be recognised in another.
    Therefore trying to save a place directly from one plugin to another is not possible.

    It is generally recommended that saving across plugins be handled as saving \l {Favorites}{favorites}
    as explained in the Favorites section.  However there is another approach which is to create a new place,
    set its (destination) plugin and then use the \l copyFrom() method to copy the details of the original place.
    Using \l copyFrom() only copies data that is supported by the destination plugin,
    plugin specific data such as the place identifier is not copied over. Once the copy is done,
    the place is in a suitable state to be saved.

    The following snippet provides an example of saving a place to a different plugin
    using the \l copyFrom method:

    \snippet declarative/places.qml Place save to different plugin

    \section2 Removing a Place

    To remove a place, ensure that a Place object with a valid \l placeId property exists and call
    its \l remove() method.  The \l status property will change to Place.Removing and then to
    Place.Ready if the save was successful or to Place.Error if an error occurs.

    \section2 Favorites
    The Places API supports the concept of favorites. Favorites are generally implemented
    by using two plugins, the first plugin is typically a read-only source of places (origin plugin) and a second
    read/write plugin (destination plugin) is used to store places from the origin as favorites.

    Each Place has a favorite property which is intended to contain the corresponding place
    from the destination plugin (the place itself is sourced from the origin plugin).  Because both the original
    place and favorite instances are available, the developer can choose which
    properties to show to the user. For example the favorite may have a modified name which should
    be displayed rather than the original name.

    \snippet declarative/places.qml Place favorite

    The following demonstrates how to save a new favorite instance.  A call is made
    to create/initialize the favorite instance and then the instance is saved.

    \snippet declarative/places.qml Place saveFavorite

    The following demonstrates favorite removal:

    \snippet declarative/places.qml Place removeFavorite 1
    \dots
    \snippet declarative/places.qml Place removeFavorite 2

    The PlaceSearchModel has a favoritesPlugin property.  If the property is set, any places found
    during a search are checked against the favoritesPlugin to see if there is a corresponding
    favorite place.  If so, the favorite property of the Place is set, otherwise the favorite
    property is remains null.
