Explanations [Edit]

The Digital Dictionary of Surnames in Germany (Q61889795) publishes new entries every two weeks, on the first and fifteenth day of the month. With every update, two lists are also updated on the DFD server:

• http://www.namenforschung.net/alle.csv – list of all published entries
• http://www.namenforschung.net/neu.csv – list of newly published entries from the last update

Both lists are formatted like the upload format for M’n’M (not yet adjusted to the M’n’M update of February 2021). The Mix’n’match catalog will soon be updated every two weeks from the first list.

Additional matching is possible with an external workflow, which produces a list ready for QuickStatements. This workflow is intended to only make unequivocal 1:1 matches and avoid constraint violations.

Discussion

Is item-requires-statement constraint (Q21503247) with language of work or name (P407) necessary?

It seems to me that item-requires-statement constraint (Q21503247) with language of work or name (P407) is used as a convenient way to check the completeness of family name (Q101352) items? The applicability of Digital Dictionary of Surnames in Germany ID (P6597) is independent of language of work or name (P407), in my opinion. Wouldn’t it be better to rely on EntitySchema:E734 for this check?

(A colleague raised the concern that this constraint might give the impression that the Digital Dictionary of Surnames in Germany ID (P6597) statement is erroneous, and I see the point.) @Jura1

Julian Jarosch (digicademy) (talk) 17:19, 19 December 2019 (UTC)

Eventually every item for a family name should have one or several such statements, but, as one can see on Property talk:P734/numbers/values for values of P734, we are far from that.

Beyond the format constraint, I don't think constraints indicate that, but I suppose we could change it to a mere suggestion (done that). --- Jura 07:00, 21 January 2020 (UTC)

conflicts-with constraint (Q21502838)

I have removed the restriction conflicts-with constraint (Q21502838) because the dictionary also contains Ukrainian, Russian, Japanese names etc. and an error is displayed when merging them, see e.g. Antonjuk (Q107453552)/Antoniuk (Q12784938) and cf. http://www.namenforschung.net/id/name/300261/1 or conflicts-with constraint (Q21502838) etc. --HarryNº2 (talk) 13:29, 8 August 2022 (UTC)
