The activity_classification table
The factor's activity hierarchy, level by level, with the publisher's own codes: what a flat sector label throws away.
Fields#

|---|---|---|---|---|
factor_id |
uuid | yes | The factor this row annotates. | |
scheme |
text | yes | Which classification scheme the code belongs to. | |
code |
text | yes | The identifier within the scheme: a real code where the scheme has one ('D', '311511'), else the segment name for a names-only publisher tree. | |
label |
text | the native label at this level | ||
level |
integer | yes | 1-based from the top | |
parent_code |
text | the node one level up, same scheme | ||

Notes#
Join across libraries only on a scheme marked is_standard.
