Within the IATI activity standard it is possible to express relations between iati-activity records across different publishers / reporting-org.
This can be described through two methods:
- related-activity - another iati-activity that has relationship to the one being described.
- transaction - both provider-activity-id & receiver-activity-id can be used to link funds from one iati-activity to another.
When using the IATI activity standard to declare related data, the following should be considered:
A related-activity can be one published by any reporting-org - it does not have to be from the same publisher.
When declaring a related-activity it is vital to include the reference to the unique iati-identifier. This enables structured links to be made.
It is also recommended to include the type of relationship that is being expressed, through use of the RelatedActivityType code.
When declaring links between different activities, it is recommended to use the related-activity element and associated RelatedActivityType code in all relevant iati-activities, so that all activities are related to each other.
- At the transaction level , it is recommended to connect iati-activity through use of the provider-activity-id & receiver-activity-id fields. Specifically:
- When an Incoming Fund (code 1) is being described, use the provider-activity-id reference to declare the immediate source of the funds, using the relevant iati-identifier of the iati-activity, if published by the provider-org
- When a Disbursement (code 3) or Commitment (code 2) is being described, use the receiver-activity-id reference to declare the immediate destination of the funds, using the relevant iati-identifier of the iati-activity, if published by the receiver-org
