24.1.11. Metadata tools

24.1.11.1. Add history metadata

Added in 3.42

Adds a new history entry to the layer’s metadata.

Parâmetros

Label	Nome	Type	Descrição
Layer	INPUT	[layer]	The input layer (vector, raster, etc.) to which the history entry will be added.
History entry	HISTORY	[string]	The text to be appended as a new entry in the layer’s history metadata. This will be added to any existing history entries.

Resultados

Label	Nome	Type	Descrição
Ficheiro de Saída	OUTPUT	[same as input]	The resulting layer with the updated history in its Metadata properties.

Python code

Algorithm ID: native:addhistorymetadata

import processing
processing.run("algorithm_id", {parameter_dictionary})

The algorithm id is displayed when you hover over the algorithm in the Processing Toolbox. The parameter dictionary provides the parameter NAMEs and values. See Usando os algoritmos do processamento a partir da consola for details on how to run processing algorithms from the Python console.

24.1.11.2. Copy Layer Metadata

Added in 3.42

Copies metadata from a source layer to a target layer. Any existing metadata in the target layer will be replaced with the metadata from the source layer. This includes all metadata fields, such as history, abstract, and other properties.

Parâmetros

Label	Nome	Type	Descrição
Source layer	SOURCE	[layer]	The layer from which metadata will be copied.
Target layer	TARGET	[layer]	The layer to which metadata will be pasted. Any existing metadata in this layer will be replaced.
Save metadata as default	DEFAULT	[boolean] Default: False	If checked, the metadata information will be saved with the layer, hence available by default in subsequent projects.

Resultados

Label	Nome	Type	Descrição
Output layer	OUTPUT	[layer]	The target layer with the metadata replaced by the metadata from the source layer. This includes all metadata fields, such as history, abstract, and other properties.

Python code

Algorithm ID: native:copylayermetadata

import processing
processing.run("algorithm_id", {parameter_dictionary})

The algorithm id is displayed when you hover over the algorithm in the Processing Toolbox. The parameter dictionary provides the parameter NAMEs and values. See Usando os algoritmos do processamento a partir da consola for details on how to run processing algorithms from the Python console.

24.1.11.3. Export Layer Metadata

Added in 3.42

Exports the metadata of a layer to a QMD file.

Parâmetros

Label	Nome	Type	Descrição
Layer	INPUT	[layer]	The layer whose metadata will be exported.
Ficheiro de Saída	OUTPUT	[file] Default: [Save to temporary file]	Specification of the output file. One of: Save to a Temporary File Save to File…

Resultados

Label	Nome	Type	Descrição
Output file	OUTPUT	[file]	The .qmd file containing the exported metadata. This file can be used to import metadata into another layer.

Python code

Algorithm ID: native:exportlayermetadata

import processing
processing.run("algorithm_id", {parameter_dictionary})

The algorithm id is displayed when you hover over the algorithm in the Processing Toolbox. The parameter dictionary provides the parameter NAMEs and values. See Usando os algoritmos do processamento a partir da consola for details on how to run processing algorithms from the Python console.

24.1.11.4. Set Layer Metadata

Added in 3.42

Applies metadata to a layer from a .qmd file.

Parâmetros

Label	Nome	Type	Descrição
Layer	INPUT	[layer]	The layer to which the metadata will be applied.
Metadata file	METADATA	[file]	The .qmd file containing the metadata to be applied.
Save metadata as default	DEFAULT	[boolean] Default: False	If checked, the metadata information will be saved with the layer, hence available by default in subsequent projects.

Resultados

Label	Nome	Type	Descrição
Output layer	OUTPUT	[same as input]	The input layer with the metadata replaced by the metadata from the .qmd file.

Python code

Algorithm ID: native:setlayermetadata

import processing
processing.run("algorithm_id", {parameter_dictionary})

The algorithm id is displayed when you hover over the algorithm in the Processing Toolbox. The parameter dictionary provides the parameter NAMEs and values. See Usando os algoritmos do processamento a partir da consola for details on how to run processing algorithms from the Python console.

24.1.11.5. Set Metadata Fields

Added in 3.42

Sets various metadata fields for a layer.

Parâmetros

Label	Nome	Type	Descrição
Layer	INPUT	[layer]	The layer whose metadata fields will be updated
Identifier Opcional	IDENTIFIER	[string]	A unique identifier for the layer
Parent identifier Opcional	PARENT_IDENTIFIER	[string]	The identifier of the parent resource, if applicable
Title Opcional	TITLE	[string]	The title of the layer
Type Opcional	TYPE	[string]	The type of data stored in the layer
Language Opcional	LANGUAGE	[string]	The language of the metadata
Encoding Opcional	ENCODING	[string]	The character encoding used in the metadata
Abstract Opcional	ABSTRACT	[string]	A brief description or abstract of the layer
Coordinate reference system Opcional	CRS	[crs]	The coordinate reference system of the layer
Fees Opcional	FEES	[string]	Information about any fees associated with accessing the layer
Ignore empty fields	IGNORE_EMPTY	[boolean] Default: False	If checked, no update will be done to metadata fields that are not filled

Resultados

Label	Nome	Type	Descrição
Output layer	OUTPUT	[same as input]	The input layer with the specified metadata fields updated.
