Planned usePopulate this property with information from the extended_from infobox parameter (after careful examination, because the meaning of this parameter is often misunderstood).

MotivationEdit

This proposal is derived from a rejected "extension of" property proposal.

For digital preservation, we need to know when a file of format A is also a valid instance of format B (see http://hul.harvard.edu/gdfr/documents/GDFR-Format-Model-and-Relationship-1_0_7.rtf, section 3.2). The property based on (P144) is related but broader (for example, EPUB 3 (Q27196933) is a restriction of ZIP (Q136218), but it is also based on (P144) Extensible HyperText Markup Language (Q166074) and Cascading Style Sheets (Q46441).  – The preceding unsigned comment was added by Dipsode87 (talk • contribs) at 10:24, September 13, 2018‎ (UTC).

  •   Comment as this seems to be meant for file formats, I added that in the description. --- Jura 10:45, 15 September 2018 (UTC)
  • I think it would be helpful if the label was more specific, to avoid misuse. --Yair rand (talk) 19:54, 17 September 2018 (UTC)

  Comment_It seems to me that subclass of (P279) can definitely do the trick. If all files within a subformat are also valid superformat files, then if any file which conforms to the format is an instance of it the restricted subformat is definitely a subclass of its parent. This make sense if you consider the definition of the format as a « class expression » that defines the properties shared by its instances. So I’d tend to   Oppose. author  TomT0m / talk page 13:26, 3 October 2018 (UTC) Note that the definition is the same than subclass of (P279) and we should not multiply the number of typing properties. author  TomT0m / talk page 13:28, 3 October 2018 (UTC)
