- Method Detail
  - getAllDatasets
```
Collection<Dataset> getAllDatasets()
```
    Returns:
    
    All available Datasets in this DatasetCatalogue. Will return null in cases where this information is not available (e.g. all Datasets are dynamically generated)
  - getDatasetFromId
```
Dataset getDatasetFromId(String datasetId)
```
    Returns a Dataset from its ID
    
    Parameters:
    
    datasetId - The ID of the dataset
    
    Returns:
    
    The desired dataset, or null if it doesn't exist in the catalogue
  - getLayerMetadata
```
EnhancedVariableMetadata getLayerMetadata(VariableMetadata variableMetadata)
                                   throws EdalLayerNotFoundException
```
    Returns EnhancedVariableMetadata giving for a given layer. This gives default values for scale range, palette etc., as well as metadata such as title, description, etc.
    
    Parameters:
    
    variableMetadata - The VariableMetadata of the desired layer
    
    Returns:
    
    Default metadata values for the desired layer
    
    Throws:
    
    EdalLayerNotFoundException
  - getLastUpdateTime
```
org.joda.time.DateTime getLastUpdateTime()
```
    Returns:
    
    The DateTime at which this DatasetCatalogue was last updated
