Items usually have a number of external identifiers. Quite a few are potential references for other statements on the Item. It would be useful to have a gadget that makes it easy to add one of the external identifiers as a reference to an existing statement on the same Item.
Thanks for creating this! I'm not sure what the standard citation reference for an external ID is, but what I've been using is:
- stated in (P248) the value of "subject item of this property" (P1629) for that external ID property, if any
- external ID property with value from the item
- retrieved (P813) on the current date.
So it would be nice if this gadget could add these three (or 2 if no P1629 value) statements as a reference with a simple interaction...
