This is used to modify the metadata associated with a file attachment.
File attachments
public String ucUploadEditObject ( HashMap formParameters, SesameSession session, Connection dbconn, String uploadObjectType, Object uploadObject ) throws Exception ;
For attachments, some parts of the object metadata are editable, e.g. the file description. There is a user custom exit for validation/modification of the edited metadata for cloud/repository upload objects.
User modification of upload objects is restricted to the file description, also known as ALT_TEXT, and the charset encoding. A user custom exit is provided to process the modifications before they are made to the object. This exit may validate the parameters, produce an error message, or allow the transaction to proceed.
