File naming conventions
DITA uses certain naming conventions and file extension for topics, maps, modules,
and
document-type implementation files.
Files that contain DITA content should use the following naming conventions:
- DITA topics
-
- *.dita (recommended)
- *.xml
- DITA maps
- *.ditamap
- Conditional processing profiles
- profilename.ditaval
Files that define DITA document-type components must use the following naming conventions:
- Document-type shell files
-
- typename.dtd
- typename.xsd
Where typename is the name of the intended root topic or map type defined by the document type shell or, as needed, a name that clearly identifies both the intended root map or topic type and distinguishes the document type shell from other shells for the same root type.
note
For example, the OASIS-provided document-type shells for technical content include two different document-type shells for the task topic type:task.dtd
andgeneralTask.dtd
, wheretask.dtd
includes the strict task body constraint module andgeneralTask.dtd
does not. - DTD structural module files
