From what i understand the diff and adiff works only on road geometry or if the version of a node/way/relation is changed.

Can you extract just the edits made by a user, on a specific time-frame, if that user added a new oneway tag.
For now, using this query, i get 2 ways, but this is not what i am looking, because the oneway tag is not added by me, it was added 3 years ago by another user.

How could i do so that i see just the tags elements that were changed between 2 dates ?

That's not exactly correct. Meta data changes, tag changes and geometry changes are all relevant.

This is currently not possible. You will always get a before / after image containing all tags as they were present in the respective version.

Hi, thanks for the quick answer.

Can we use the if: condition to filter ?

I`m guessing no based on your answer.

I also understand now that i was getting the created for all of the tags because there is a new user on this query, compared to the old query.

Not sure, how you want to use if: in this scenario. Can you elaborate a bit?

Yes exactly, when running the query with [date:2017-05-01T00:00:00Z] and (user:"florinbadita_telenav") you wouldn't get any result, as the way was changed by another user at that time. That's why diff & adiff return version 3 as created.
