{{ContentService }} provides {{read }} and {{write }} operations on a node, the latter either as a byte array or file attachment.\\

{{Clear }} can remove properties from a node, including the {{content }} property.

{{Transform}} can transform the file content of a node from one mime type to another, from {{doc}} to {{pdf}}, for example.  If the {{ImageMagick}} software application is made available to Alfresco, image transformations are possible
