Access relationships

AccessRelationship.accessType is exposed as:

type ArchiAccessType = 'Write' | 'Read' | 'Unspecified' | 'ReadWrite';

It is decoded from Archi’s native 0–3 attribute representation. The enumeration follows Archi’s own IAccessRelationship constants (WRITE_ACCESS, READ_ACCESS, UNSPECIFIED_ACCESS, READ_WRITE_ACCESS) rather than the ArchiMate Open Exchange AccessTypeEnum vocabulary — which uses "Access" for the unspecified case. That is a different format’s naming, not this one’s.

Defaults

For an AccessRelationship, the field is always resolved to a value:

• when the native attribute is present, it is decoded;
• when absent, the parser uses Archi’s native default: 'Write'.

For every other relationship type, accessType is null.

Example

const access = model.relationships.filter(
  (r) => r.type === 'AccessRelationship',
);

for (const rel of access) {
  console.log(rel.sourceId, '->', rel.accessType, '->', rel.targetId);
}
