[DDI-users] DDI Version 2.0 Published

[Mary Vardigan]

Dear Colleagues,

The Alliance for the Data Documentation Initiative (DDI) announces a 
new version of its Document Type Definition (DTD) and a newly revised 
Web site.

Version 2.0 of the specification incorporates several enhancements, 
most notably an aggregate/tabular data extension that permits the 
markup of aggregate data. The comments history section of the DTD 
delineates all of the revisions to the DTD since Version 1.0 was 
published in 2000. To view the new DTD:

The Web site (http://www.icpsr.umich.edu/DDI) also has some new 
features, including

A FAQ page: http://www.icpsr.umich.edu/DDI/codebook/faq.html

Please review the new site and send suggestions for improving it to

effort.

Regards,
Mary
