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.
For example, the OASIS-provided document-type shells for technical content include two different document-type shells for the task topic type: task.dtd and generalTask.dtd, where task.dtd includes the strict task body constraint module and generalTask.dtd does not.
DTD structural module files
◦ typename.mod
◦ typename.ent
DTD domain module files
◦ typenameDomain.mod
◦ typenameDomain.ent
DTD constraint module files
constraintnameConstraint.mod
Schema structural module files
◦ typenameMod.xsd
◦ typenameGrp.xsd
Schema domain module files
typenameDomain.xsd
Schema constraint module files
◦ constraintnameConstraintMod.xsd
◦ constraintnameConstraintIntMod.xsd
