File names in the base DITA edition

The OASIS DITA Technical Committee uses certain conventions for the names of XML grammar files. We suggest using these conventions as a way to facilitate the interchange of grammar files.

DTD-based specialization modules

The DITA Technical Committee uses certain file-naming conventions for DTD-based specialization modules. While the grammar files shipped with DITA 2.0 do not include domain constraint or expansion modules, we suggest conventions for those modules also.

Module type File name Example
Structural moduleName.mod topic.mod
Element domain domainNameDomain.ext
  • highlightDomain.ent
  • highlightDomain.mod
Attribute domain attriNameAttDomain.ent deliveryTargetAttDomain.ent
Constraint qualifierTargetConstraint.mod
  • strictTaskbodyConstraint.mod
  • acmeHighlightDomainConstraint.mod
Expansion
  • acme-SectionExpansion.mod
  • acme-CellPurposeAttExpansion.ent
  • acme-otherpropsAttExpansion.mod
  • example-dlentryModeAttExpansion.ent

where:

  • moduleName is the name of the element type, such as "topic" or "map".
  • domainName is the short name of the domain, for example, "highlight" or "utilities".
  • attrName is the name of the specialized attribute, for example, "deliveryTarget".
  • ext is the file extension, for example, "ent" or "mod".
  • qualifier is a string that is specific to the constraints module and characterizes it, for example, "strict" or "requiredTitle" or "myCompany-".
  • Target is the target of the constraint with an initial capital, for example, "Topic" or "HighlightDomain".

RELAX NG-based specialization modules

The DITA Technical Committee uses certain file-naming conventions for RNG-based specialization modules. While the grammar files shipped with DITA 2.0 do not include domain constraint or expansion modules, we suggest conventions for those modules also.

Module type File name Example
Structural moduleNameMod.rng conceptMod.rng
Element domain domainNameDomainMod.rng highlightDomainMod.rng
Attribute domain attrNameAttDomain.rng deliveryTargetAttDomain.rng
Constraint qualifierTargetConstraintMod.rng
  • strictTaskbodyConstraintMod.rng
  • acmeHighlightDomainConstraintMod.rng
Expansion
  • sectionExpansionMod.rng
  • cellPurposeAtt.rng
  • acme-otherpropsAttExpansion.rng
  • tableCellAttExpansion.rng

where:

  • moduleName is the name of the element type, such as "topic" or "map".
  • domainName is the short name of the domain, for example, "highlight" or "utilities".
  • attrName is the name of the specialized attribute, for example, "deliveryTarget".
  • qualifier is a string that is specific to the constraints module and characterizes it, for example, "strict" or "requiredTitle" or "myCompany-".
  • Target is the target of the constraint with an initial capital, for example, "Topic" or "HighlightDomain".
