Activity file


The activity file contains the data defined by the IATI activity standard.

It is an XML file, containing the relevant IATI activity standard fields for the publishing organisation.


When using the IATI activity standard to produce an iati-identifier, the following should be considered:

  • An IATI publisher should publish at least one activity file.

  • An activity file should contain at least one iati-activity

  • It should be updated at least annually.

  • It must be well-formed XML.

  • It must validate against the relevant version of the **IATI activity schema**

  • Any activity file must have iati-activities as the root element - to contain all other elements.

  • The generated-datetime attribute of iati-activities - a date/time stamp for when the activity-file was generated - is highly recommended.

  • The generated-datetime is declared at the iati-activities level. Is not necessarily the same as the last-updated-datetime for the individual iati-activity records within it.

  • Across a set of activity files published by a single organisation, individual iati-activity, referenced via a unique iati-identifier, should not be duplicated.

  • A link to the activity file(s) should be published on the IATI Registry.

  • Ideally, this link would be to an activity file(s) on the publisher website or open data portal. However, third party tools are available to generate and host files on behalf of publishers.

  • When creating the activity file it is recommended to avoid spaces and non-ascii characters in file names and urls. For example:
    • iatiactivity.xml is preferable to IATI Activity.xml.
    • is preferable to data/IATI Activity.xml.
