Feature summary (what you would like to be able to do and where):
It should be possible to download a sanitized database dump of the linktarget table (see T305064) from dumps.wikimedia.org or a mirror site. Alternatively, the lt_namespace and lt_title columns of the linktarget table should be added to the templatelinks dumps, and in the future the other links table dumps. (The exact dump format doesn't matter too much; SQL, CSV, TSV, XML, and JSON probably would all be OK.)
Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
The tl_namespace and tl_title columns of the templatelinks table are being dropped. In a message posted to wikitech-l ("Changes in schema of MediaWiki links tables"), @Ladsgroup said:
So if you: [...] … rely on dumps of these tables [the links tables], you will need to change your scripts.
Currently, the contents of the linktarget table are not part of the publicly available SQL dumps (there are no references to "linktarget" in the dumps generation code), so it may not be possible to fix existing scripts that process dumps of the links tables. (While I do not have any such scripts, others might.)
Benefits (why should this be implemented?):
This would allow scripts to continue to extract usable data from the publicly available templatelinks SQL dumps. Without the target titles, the templatelinks data are largely meaningless.
