After removal, will this extension be archived? Or can still be used on non-WMF wikis?

Thank you for pointing out the needs related to the Education Extension. It seems clear to everyone that data will not be lost, and that the Programs & Events Dashboard provides a practical, easy-to-use alternative.

As it has been pointed out, work is needed to make the past data of the education extension accessible. This is not yet solved, but the security issues that the use of the education extension presents to the few that were still using it will.

Is it still June 30, 2018?

I find it very sad that we'd remove an extension without documenting access to old data or publishing them somewhere so that anyone can easily find them and analyze them.

From the tool labs db replicas

MariaDB [enwiki_p]> SHOW TABLES LIKE 'ep_%';

According to https://github.com/wikimedia/puppet/blob/ffedf9b4545817306669d9ca4161b61629ee0d14/modules/profile/templates/labs/db/views/maintain-views.yaml#L56-L64 9 of the 10 tables are 1:1 viewed

ep_courses seems to just null out course_token as null which is fair enough

https://github.com/wikimedia/puppet/blob/ffedf9b4545817306669d9ca4161b61629ee0d14/modules/profile/templates/labs/db/views/maintain-views.yaml#L300-L307

So basically, you could get the data as is, straight from the db replicas on tool labs.

The data wouldn't be immediately deleted. Based on previous experience, it would still be here years from now, but we're better at cleaning it up. I saw T186325

It shouldn't be too much work to do SQL dumps of all the ep_ tables on the wikis with education program installed, and sticking it with https://dumps.wikimedia.org/other/wep/ which has some signup data from the EducationProgram.

Thank you for moving forward with the Education Extension removal. In particular, @Legoktm and @Reedy thank you for taking the necessary technical steps.

@Vojtech.dostal is what is proposed by @Reedy in terms of access to data helpful? I personally don't think that data from the Education Extension should be deleted at all, since as you point out, it might prove to be valuable (ie. for research purposes) at a later point in time.

The data should and will be deleted from the wiki databases in the (near) future. When the extension is undeployed, it's orphaned, and is an extra maintenance burden for our DBAs.

However, archives/backups of the data will be taken, and should be made publicly available

Thanks for the clarification @Reedy . And the existence of the backups would be announced somewhere on Meta?

Did that ever happen? T186325: Retaining data for courses organized through the extension during and after deprecation period doesn't show much action...

Not really. Waiting on T174802. If we make the extension readonly everywhere, and then blank out out the course token for ease...

That gives us a month or so before removing the extension. (see: T174802#4733544)

Should this be closed as resolved?

https://codesearch.wmflabs.org/deployed/?q=EducationProgram

if ( $wmgUseEducationProgram ) {
	$wgExtraNamespaces[446] = 'Education_Program';
	$wgExtraNamespaces[447] = 'Education_Program_talk';

'wmgUseEducationProgram' => [
	'arwiki' => true,

 case 'educationprogram':
		$files = [ 'EducationProgram.sql' ];
		$path = "$IP/extensions/EducationProgram/sql";

It seems that, while extensions/EducationProgram no longer exists in prod, the namespace is still being created on ar.wikipedia.org.

And other wikis. See T211494: Re-enable EP Namespaces in wmf-config
