Data extraction: handling of tags that have same key as a property (e.g. @osmId)

[FabiKo117]

As raised in a discussion in another issue, how should we deal with tags that also start with the "@" sign?

Escaping them through adding a 2nd @ could be a good way to go. This would only be necessary though on tags that have the same name as one of our property, e.g. the @osmId tag and not on all tags starting with @.

Thanks for excluding that from the other issue.

I would suggest to change all keys matching ^@ to @@, document that, and for the very rare cases someone wants to use that tags, we don't have a problem there.

Yeah we could also do it like that. As you say it would then just be important to document it properly, because if the user would request then for @ the response actually has @@ at the start of the tag.
