Access Metadata of Segments & Trees in Annotations

[fm3]

scalableminds/webknossos#7875 introduces metadata for segments and trees and extends the NML format to include it. The libs should allow accessing it. We should discuss what the interface should look like.

Hi @fm3, is there a way to use get_volume_layer_segments() to get the segment_id/name mapping without downloading the volume annotation NML file? Thank you.

As I understand it, the python libs currently access the contents of annotations via the downloaded NML file. So I’m afraid the download step is not optional. Eventually, we may build APIs to interact with individual elements of annotations without the download step, but as far as I know that is not on the short-term agenda.
Tackling this issue concerning the new segment metadata will also be based on NML as an exchange format.

Thanks for the quick response, @fm3. That sounds good.
