class QgsLayerMetadata : QgsAbstractMetadataBase
{
%Docstring
A structured metadata store for a map layer.

QgsLayerMetadata handles storage and management of the metadata
for a QgsMapLayer. This class is an internal QGIS format with a common
metadata structure, which allows for code to access the metadata properties for
layers in a uniform way.

The metadata store is designed to be compatible with the Dublin Core metadata
specifications, and will be expanded to allow compatibility with ISO specifications
in future releases. However, the QGIS internal schema does not represent a superset
of all existing metadata schemas and accordingly conversion from specific
metadata formats to QgsLayerMetadata may result in a loss of information.

This class is designed to follow the specifications detailed in
the schema definition available at resources/qgis-resource-metadata.xsd
within the QGIS source code.

Metadata can be validated through the use of QgsLayerMetadataValidator
subclasses. E.g. validating against the native QGIS metadata schema can be performed
using QgsNativeMetadataValidator.

If QgsDateTimeRange.isInfinite() returns true then the temporal extent
is considered to be indeterminate and continuous.

Sets the ``fees`` associated with using the resource.
Use an empty string if no fees are set.

Sets a list of ``rights`` (attribution or copyright strings) associated with the resource.

Returns the character encoding of the data in the resource. An empty string will be returned if no encoding is set.

Sets the character ``encoding`` of the data in the resource. Use an empty string if no encoding is set.

    QgsCoordinateReferenceSystem crs() const;
%Docstring
Returns the coordinate reference system described by the layer's metadata.

Note that this has no link to :py:func:`QgsMapLayer.crs()` While in most cases these
two systems are likely to be identical, it is possible to have a layer
with a different CRS described by it's accompanying metadata versus the
CRS which is actually used to display and manipulate the layer within QGIS.
This may be the case when a layer has an incorrect CRS within its metadata
and a user has manually overridden the layer's CRS within QGIS.

The CRS described here should either match the CRS from the layer :py:func:`QgsMapLayer.crs()`
or the CRS from the data provider.

This property should also match the CRS property used in the spatial extent.

.. seealso:: :py:func:`setCrs`
%End

    void setCrs( const QgsCoordinateReferenceSystem &crs );
%Docstring
Sets the coordinate reference system for the layer's metadata.

Note that this has no link to :py:func:`QgsMapLayer.setCrs()` Setting the layer's
CRS via QgsMapLayer.setCrs() does not affect the layer's metadata CRS,
and changing the CRS from the metadata will not change the layer's
CRS or how it is projected within QGIS.

While ideally these two systems are likely to be identical, it is possible to have a layer
with a different CRS described by it's accompanying metadata versus the
CRS which is actually used to display and manipulate the layer within QGIS.
