A structured metadata store for a map layer.
QgsProjectMetadata handles storage and management of the metadata for a QgsProject. This class is an internal QGIS format with a common metadata structure, which allows for code to access the metadata properties for projects 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 QgsProjectMetadata may result in a loss of information.
This class is designed to follow the specifications detailed in the schema definition available at resources/qgis-project-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 QgsNativeProjectMetadataValidator.

void QgsProjectMetadata::setCreationDateTime | ( | const QDateTime & | creationDateTime | ) |
Sets the project's creation date/timestamp.
Definition at line 85 of file qgsprojectmetadata.cpp.
|
overridevirtual |
Stores state in a DOM node.
metadataElement | is a DOM element corresponding to ``resourceMetadata'' tag |
