Once decided, we need to update pretty much all classes in Speech Data Collector (which is lacking this annotation all together), and perhaps in the Wikispeech extension too.

I.e. adding this between the namespace statement and use statement:

/**
 * @file
 * @ingroup Extensions
 * @license GPL-2.0-or-later
 */

This was identified by Danny in https://gerrit.wikimedia.org/r/c/mediawiki/extensions/WikispeechSpeechDataCollector/+/638485/1/includes/UUID.php

For MediaWiki-compatibility we chose GPL-2.0-or-later for Wikispeech. Anyhow the missing tags should probably all be added in a single patch. I thought being default for non-MediaWiki code, but can't find it.

@kalle Might also be worth taking a quick look at the Wikispeech repo to make sure this isn't missing from any of the files (spotted it on SpeechoidConnectorException)

A patch for Wikispeech SDC attached to this task will be created when ApiCRUD has been merged.
