    \class QPlace
    \inmodule QtLocation
    \ingroup QtLocation-places
    \ingroup QtLocation-places-data
    \since 5.6

    \brief The QPlace class represents a set of data about a place.

    \input place-definition.qdocinc

    \section2 Contact Information
    The contact information of a place is based around a common set of
    \l {Contact Types}{contact types}. To retrieve all the phone numbers
    of a place, one would do:

    \snippet places/requesthandler.h Phone numbers

    The contact types are string values by design to allow for providers
    to introduce new contact types.

    For convenience there are a set of functions which return the value
    of the first contact detail of each type.
    \list
        \li QPlace::primaryPhone()
        \li QPlace::primaryEmail()
        \li QPlace::primaryWebsite()
        \li QPlace::primaryFax()
    \endlist

    \section2 Extended Attributes
    Places may have additional attributes which are not covered in the formal API.
    Similar to contacts attributes are based around a common set of
    \l {Attribute Types}{attribute types}.  To retrieve an extended attribute one
    would do:
    \snippet places/requesthandler.h Opening hours

    The attribute types are string values by design to allow providers
    to introduce new attribute types.

    \section2 Content
    The QPlace object is only meant to be a convenient container to hold
    rich content such as images, reviews and so on.  Retrieval of content
    should happen via QPlaceManager::getPlaceContent().

    The content is stored as a QPlaceContent::Collection which contains
    both the index of the content, as well as the content itself.  This enables
    developers to check whether a particular item has already been retrieved
    and if not, then request that content.

    \section3 Attribution
    Places have a field for a rich text attribution string.  Some providers
    may require that the attribution be shown when a place is displayed
    to a user.

    \section2 Categories
    Different categories may be assigned to a place to indicate that the place
    is associated with those categories.  When saving a place, the only meaningful
    data is the category id, the rest of the category data is effectively ignored.
    The category must already exist before saving the place (it is not possible
    to create a new category, assign it to the place, save the place and expect
    the category to be created).
