Motivation

A law can be amended, substituted/superseded or repealed without replacement. Such properties are usually in pairs. For example, substitution/supersession can be indicated by replaces (P1365) and replaced by (P1366). Repeal can be indicated by repeals (P3148) and repealed by (P2568). But for amendment, there is only amended by (P2567). The inverse property is required for cross-linking from amending law to principal law. Hrishikes (talk) 15:27, 19 November 2019 (UTC)

•  Oppose Generally, crosslinking isn't desireable in Wikidata as it produces data doublication. Data-users can query the inverse relationship when they are interested in it. ChristianKl ❪✉❫ 10:14, 20 November 2019 (UTC)

As far as I can see, Wikidata has plenty of paired cross-linking. Like, when son is linked to from father's item, father is also linked to from son's item. replace and replaced by are also paired and the system insists on cross-linking. All personal relationships are also like that. In this case, if principal law is not to be linked to from amending law, how should this matter be shown in the item for the amending law?

Wikidata's goal is not just to be consumed via the Wikidata user interface, it can be used in all sorts of ways by data consumers who can query the data.

Within the Wikidata user interface there's no the relatedItem's gadget that allows users to see inverse items. The existence of that new gadget also coincided with us deprecating a few older inverse relation properties. ChristianKl ❪✉❫ 10:02, 2 December 2019 (UTC)
