The Athena Institute is working on a WBLCA guideline and benchmark initiative aiming to address some of the mentioned points: scope, categories, BOM reporting, etc. It includes standardizing naming convention which already has another thread on this forum. @matt.bowick may be able to share more? I think the short answer is that there are the CSI, UniFormat and OmniClass naming and categorization schemes, but none of them goes far enough for WBLCA purposes.
