This should be in the schema along with everything else we produce, and the version updated.

I think Flow stuff should preferably not be in the core schema, since Flow is not part of core and there is a separate script for exporting Flow (Flow/maintenance/dumpBackup.php).

So where are we on this? Can we get it published someplace at any rate?

Flow dumps XSD schema

https://gerrit.wikimedia.org/r/275843

Patch in gerrit. Writings XSDs is not something I do every day, please review carefully and provide abundant feedback :)

As Brion pointed out in review: do we need the schema?

We don't *really* need it, so do we want the validation badly enough ourselves that we want to maintain this?

In other words: does anyone object to not having the schema?

How will I know how to write code that processes the dump? Currently, I use the export XML schema to program against the MediaWiki XML dumps. See https://www.mediawiki.org/xml/export-0.10.xsd

If you want to describe these schema in some form other than XML schema, I think that is fine, but I don't think it is a good idea to produce a dump with no description of what it contains and what fields are required/repeatable.

In addition to validation, XSDs can also be used for code generation. We should probably do it.

Alright let's get this merged then.

Where will we put the schema/namespace (xmlns & xsi:schemaLocation)?

I guess the most straightforward is docroot/mediawiki/xml/Flow in operations/mediawiki-config.

That would then correspond to mediawiki.org/xml/Flow as you'd expect. I guess docroot/mediawiki/xml/flow might be better.

I would expect lowercase , not uppercase. It is case sensitive, and I can't recall the last time I've encountered caps in a namespace.

Add Flow dumps schema

Naming seems to be like this: docroot/mediawiki/xml/project-version
That's what I've now changed the patch(es) to. I think they're ready to go.
