Hello, I appreciate the reply. I tried for a couple hours to modify the existing osmxml.js part of ol.js.map offline to parse the `timestamp` with `getAttribute` similarly to how `lat`...

The easy (and obvious) workaround to this was to simply convert it to GeoJSON using [osmtogeojson](https://tyrasd.github.io/osmtogeojson/) which adds the metadata tags as feature properties. So it's effectively solved.
