Determining the Input File Type

Publishing Engine Programmer's Guide > The Arbortext Publishing Engine Sub-Process > Arbortext Publishing Engine Document Conversion > Loading a Document for Conversion > Determining the Input File Type

For a POST request, the input file type can be specified by the file-type=type parameter. If no file-type parameter is specified, the conversion processor attempts to determine the input file type by examining the file extension. The supported input file types, the file-type=type parameter values, and the associated file extension mapping are described in the following table.

Input file types
Input file type	file-type parameter values	File extension
SGML	sgml	.sgm, .sgml
XML	xml	.xml, .dita, .ditamap
HTML	html	.htm, .html
Microsoft Word	word	.doc, .docx
Adobe FrameMaker	frame	.mif
Rich Text Format	rtf	.rtf
Text	text	.txt
PDF	pdf	.pdf
Zip archive	zip	.zip

For a POST request passing the input file as the HTTP request body (no file or file-type parameter specified), the conversion processor determines the input file type according to the HTTP header parameter content-type as follows:

Mapping content-type header to input file type
Header value	Input file type
application/msword	Microsoft Word
application/pdf	PDF
application/rtf text/rtf	Rich Text Format
application/vnd.framemaker application/x-framemaker application/x-frame	Adobe FrameMaker
application/zip	zip archive
text/html	HTML
text/plain	Text
text/sgml	SGML
text/xml	XML.
