Attributes

Attribute	Type	Cardinality	Description
id :pathway/id	string	oneunique identity	Globally unique id for this pathway. MUST be prefixed with its source ontology, lowercased, joined with ':' -- e.g. 'metacyc:PWY-7754' (the bare MetaCyc id 'PWY-7754', stripped of HUMAnN3's appended ': description' suffix, then qualified) -- NOT the bare 'PWY-7754'. :pathway/source is a separate, non-identity field and cannot itself disambiguate two different sources that happen to produce the same bare id string; :db.unique/identity only ever looks at this attribute's own value. This follows the same self-constructed composite-string-as-id convention already used by :variant/id (joins genomic coordinates + alleles) rather than a synthetic-composite-id/metamodel-level composite (as :otu/:sgb use), since :pathway is a global, not measurement-set-scoped, ref-data kind and doesn't need their per-uid machinery -- just a value guaranteed unique by construction.
name :pathway/name	string	one	Human-readable pathway description, e.g. 'bile acid 7-alpha-dehydroxylation'.
source :pathway/source	pathway.source	one	The source ontology for this pathway id, refers to idents in the 'pathway.source' namespace (e.g. :pathway.source/metacyc). This field is for querying/display only -- it is NOT part of :pathway/id's identity computation, so it cannot by itself prevent an id collision between sources; see :pathway/id's doc for the actual disambiguation mechanism (prefixing the id string itself).
