The content of opendata.stackexchange.com (https://opendata.stackexchange.com/), a Stack Exchange question-and-answer site, as published in the Stack Exchange Data Dump of April 2024 on the Internet Archive. The posts table holds 26,217 rows: 14,024 posts (6,180 questions, 7,265 answers, 288 tag wiki excerpts, 288 tag wikis and 3 posts of type 6) and 12,193 comments, written between 26 January 2013 and 30 March 2024. Beside it are 27,442 user accounts, 48,430 votes, 31,636 badges awarded, 310 tags, 47,819 post revisions and 975 links between posts. Every answer keeps the question it answers and every comment the post it was written on, so the threads can be rebuilt. The Internet Archive item describes the dump as anonymised; the votes table names the voter in only 144 rows.
