Griffith said the Memorandum of Understanding for Staroffice 6.0, agreed by the software supplier and the public sector IT managers' association, will provide users with a "substantial discount" on the software's list price as well as support and maintenance. The deal covers the whole of the UK public sector, including local authorities.
"This is putting the various parts of the jigsaw in place to achieve what users want," said Griffith.
"Whereas Staroffice was not supported before because it was free on the Internet, now we have support."
The Memorandum of Understanding builds on a deal involving Socitm and Sun that that was announced earlier this year.
Socitm will be running a one-day seminar in London on 3 July to explore the long-term implications of implementing an open source desktop and the issue of interoperability.
