IATI recognises that an organisation is unlikely to have all of the information set out in the IATI Standard available for immediate publication. An organisation can therefore work with whatever information they currently have available with the aim of adding to this as they progress through the IATI process. The Implementation Schedule allows organisations to identify what information is available for immediate publication, what is only partially publishable (e.g. may require further information to be added in before reaching full compliance), and what will be published at a future date. It also enables organisation to state what data is not available, whether this is due to exclusions or it not being applicable to the organisation for example, and what is not currently captured but could be considered for publication at some stage.
The availability of data will also depend on how information is currently captured and stored – i.e. does it need to be drawn from different places to meet IATI requirements? Delays in publishing beyond what is immediately available could therefore be due to having to put new systems in place to integrate data capture mechanisms.
