Microsoft Office Project 2007 can save and import project data in an XML file for exchanging data with other applications. The Project 2007 XML Data Interchange Schema (mspdi_pj12.xsd) defines the XML elements used to represent Project 2007 data in XML format.

The XML elements defined in the Project Data Interchange Schema use the following data types for text values.

Date and time data, provided in the format YYYY-MM-DDTHH:MM:SS.


An arbitrary precision number.


A duration of time, provided in the format PnYnMnDTnHnMnS where nY represents the number of years, nM the number of months, nD the number of days, T the date/time separator, nH the number of hours, nM the number of minutes, and nS the number of seconds.

For example, to indicate a duration of 1 year, 2 months, 3 days, 10 hours, and 30 minutes, you write: P1Y2M3DT10H30M. You could also indicate a duration of minus 120 days as -P120D.
