[00:28:16] hmm, I hope VIAF corrects their entries [11:51:12] I am still somewhat confused about times in wikidata. For example, take https://www.wikidata.org/wiki/Q23104 (year 0) and https://www.wikidata.org/wiki/Q161251 (0s BC). What should we use as Point In Time (P585) for those? Right now, they seem to use invalid dates (0 / 0 BCE) [12:24:15] it was also surprising to see how often 29. Februar appears in Wikidata [12:35:17] should I still specifiy reference URL if I use an external identifier (such as a library identifier) as reference? [12:35:24] or is it enough to specify that identifier? [15:41:56] Is end time (P582) inclusive or exclusive?
