They are dependent on the current back-end routines. Authorization is done in the back-end making that code reusable. This would be advantageous in deploying a Java user interface while retaining HTTP data connectivity. Our move to Java will probably supersede this, implementing Java on server also. A default routine supports common processing.
Custom routines support repeating items.
Import protocols are treated generally. Currently supported protocols are NFS and mail. Like-named routines place inbound objects into the user inbox, with partial metadata. Similarly, datatypes supported by the EFC include recognizers supporting user interface and conversion routines. User interface and data storage design generalizes several stored resolutions into a single datatype.
