Relationships between classifications

How relationships are presented in the Dictionary

Relationships are held 'both ways round', e.g. the relationship between BAP Broad habitat "Broadleaved, mixed and yew woodland" and Phase 1 habitat "Woodland: broadleaved, semi-natural" is recorded as:

Classification 1	Habitat name	Relationship	Classification 2	Habitat name
BAP BROAD	Broadleaved, mixed and yew woodland	contains	PHASE 1	Woodland: broadleaved, semi-natural
PHASE 1	Woodland: broadleaved, semi-natural	is contained in	BAP BROAD	Broadleaved, mixed and yew woodland

The commonest types of relationship are "is equal to", "contains" (i.e. one habitat type includes all of another), "is contained in" (i.e. the converse), and "overlaps with" (i.e. the habitat distinctions differ between classifications, sometimes in a poorly described way).
