Feature request: Get history of object only partly

[Andre Hinrichs-2]

Hi!

Sometimes histories of objects become very long and therefore history
requests of such objects take long and likely stress the API too.

Thus, I think it is useful to be able to get only a portion of the
history (e.g. a specific range of the most recent ones).

Maybe it's also useful to query a specific version of an object. In this
case there could be a query for some kind of history overview of this
object only listing the version, date, changeset and user.

Since this will be a change in the API I'd like to request this feature
for the next API version.

Or are there already any plans for this?

Any thoughts?


Regards

Andre

This does not need an API version change.

You can already get a specific version of a node/way/relation. You append the version number to the url (after a forward slash). For example:
http://www.openstreetmap.org/api/0.6/relation/73447/124
<http://wiki.openstreetmap.org/wiki/API_v0.6#Version:_GET_.2Fapi.2F0.6.2F.5Bnode.7Cway.7Crelation.5D.2F.23id.2F.23version>

The data browser needs to be updated to be able to show specific versions of each node/way/relations. I have been meaning to do it for a while now, just not had the time to get around to it.
