May 2007. DExT commissions the Open Data Foundation (ODaF) to work on survey standards and tools

We are pleased to announce that the UK Data Archive (UK Data Archive) and the Open Data Foundation (ODaF) have agreed to initiate a collaborative project for the development of data archiving and conversion tools. Supported by the UK Data Archive Data Exchange Tools (DExT) initiative, the project aims at the development of open source utilities for the conversion of quantitative data into a standard archiving format and export to common statistical packages or database systems. This initial phase is a proof of concept that will focus on using SPSS as an input format and support export to SPSS, Stata, SAS and ASCII. The archiving format will be based on a combination of fixed ASCII data and DDI metadata. Developments are expected to begin in June with product delivery scheduled for end of November 2007. This work will lay the foundation for more advanced tools that can support additional input and output formats and provide enhanced functionalities.
