Temporary storage

The following pipeline components can be used for storing and retrieving data from temporary storage (i.e., a dictionary) that is available through the session object of the pipeline:

• delete-storage - filter that removes the name storage item
• from-storage - reader retrieves the named storage item
• set-storage - filter that updates the storage with the data passing through
• to-storage - writer that updates the storage with the data arriving

For annotations, you can use these specialized filters:

• annotations-from-storage - replaces the annotations of the current container with the ones from storage
• annotations-to-storage - pushes the annotations of the current container into internal storage
