Alexander WinklerI had never used (or heard of) the 'DESCRIBE' form in <a href="https://openbiblio.social/tags/SPARQL" class="mention hashtag" rel="nofollow noopener" target="_blank">#SPARQL</a>.

Till GrallertI just added holding information for 100+ Arabic newspapers and magazines published before 1930 from the National Library of Israel to <a href="https://digitalcourage.social/tags/Wikidata" class="mention hashtag" rel="tag">#Wikidata</a> (many are marked as belonging “to the Absentee Property Collection (AP)” in the MARC files from the catalogue and thus a direct result of the <a href="https://digitalcourage.social/tags/Nakba" class="mention hashtag" rel="tag">#Nakba</a> ).
