       FTP

The FTP doctype has been designed to support the distribution of binary data (via Z39.50 or HTTP) from FTP archives that adhere to the guidelines for FTP publication from the IAFA-WG. Like the BINARY doctype it has been designed to manage software archives, CAD drawings and non-textual information. The FTP document model offers much more control than the Binary model, but is a bit more complicated.

A "FTP" file consists of 2 (two) components, a IAFA description and the binary file itself. Looks for a file .iafa that contains the text information (eg. for "x.tar" looks for "x.tar.iafa"). All the fields in the IAFA description are searchable.

The FULLTEXT ("F") attribute: returns the binary file.
The MIME type for Raw: is specified in the IAFA file with the field Content-type. If not defined the default is "Application/Octet-Stream".
