Relationships are used to link organisation entities together. These can imply genuine operational links, indicating commissioning or provision, lines of authority or virtual geographical associations.

Relationships – how it works

Any organisation record can be linked to one or more others via relationships.

There is no rigid hierarchy within the model (i.e. any record may be linked to any other record).

The different sides of a Relationship are termed ‘Subject’ (the record that holds the relationship reference) and ‘Target’ (the related Organisation that is referenced)

Relationships are ‘one-way’ – that is, they are only hosted by one of the entities in the pairing

There is no restriction on the number of times a record may be referenced as a Target from other Subject records.

Relationship information is contained in an element tagged ‘Rels’ in the Organisation component of the XML file. Within this element will be one or more elements tagged ‘Rel’, each of which contain the details of one of the Relationships for the Subject entity. Each of these Relationships will include a unique identifier, a name to give context, status and a timespan, as well as a range of information about the target entity including its own identifier.

Relationship names

Relationships are categorised with a Named Relationship value that indicates a context for the Relationship. There are 6 at present but more may be added in future.
