Object Icon in Outliner

[oct]

As far as I can tell the bold triangle icon represents object data block

But it’s not listed in the doc. https://docs.blender.org/manual/en/dev/files/data_blocks.html#making-single-user

If it is Object icon, shouldn’t Outliner be using the same Object icon in Properties panel?

No, the bold triangle represents a mesh object (i.e. an Object that contains Mesh data). Camera and Light are also Objects, with their own respective icons. So are curves, metaballs, surfaces, armatures…
