This is part of the formal proposal that makes up the first iteration of the Version 2.01 Upgrade process.
The current standard has very few mandatory fields. The main reason for this is that in Version 1.01 all mandatory validation was done via the XML Schema, and it is very difficult using XML logic alone to apply such rules. Additional validation procedures have since been established to now propose that all activities under all circumstances should always contain:
The reporting-org element is MANDATORY.
ALL the following rules must apply to the organisation-identifier in reporting-org/@ref
It is mandatory
The agency prefix MUST be a valid code in the IATI code list
The identifier MUST be the prefix to the iati-identifier
The identifier MUST be the same as that recorded by the publisher on the IATI Registry
The identifier MUST only contain alphanumeric characters and hyphen, underscore, colon or period
