There are lot's of industry standard formats - FBX and Collada, U3D, Alembic, MDD.... However, in this case I think "industry standard" is referring not to formats but to technologies - weight-mapping, especially single-skin weight-mapping, is industry standard; unfortunately TriAx weight-mapping (or the Poser equivalent) aren't. Dual Quaternion weight-maps are industry standard; bulges on joints aren't. UDIMs are industry-standard(ish), stacked UVs aren't.
