A DTD defines the valid building blocks of an XML document. It defines the document structure with a list of validated elements and attributes. DTD files are plain text. Web archives should never be migrated, as that would change the fundamental linkages and functionality of web objects. Uncompiled code that is plain text ASCII or Unicode does not require format migration." ; dcterms:identifier "NF00162" ; rdfs:label "NF00162" ; wikidata:p1163 "application/xml-dtd" ; wikidata:p1195 "dtd" ; wikidata:p2748 "https://www.nationalarchives.gov.uk/PRONOM/x-fmt/315" ; wikidata:p3266 "https://www.loc.gov/preservation/digital/formats/fdd/fdd000076.shtml" ; wikidata:p3381 "http://fileformats.archiveteam.org/wiki/DTD" ; wikidata:p973 "https://en.wikipedia.org/wiki/Document_type_definition" ; wikidata:p973 "https://www.w3.org/TR/REC-xml/#dt-doctype" ; wikidata:p973 "https://www.wikidata.org/wiki/Q212327" ; nara:category naraid:Code ; nara:category naraid:Textual ; nara:category naraid:Web ; nara:formatName "eXtensible Markup Language Document Type Definition" ; nara:preservationAction naraid:Retain ; nara:preservationPlan "Retain" ; nara:riskLevel naraid:Low ; nara:tools "Any supported text editor" ; . a owl:Ontology ; .
