A complete revised version of the Uniform Description System for Materials on the Nanoscale 
(UDS) is now available for download. Version 2.0 of the UDS is the result of two years of work and meetings by the CODATA-VAMAS Working Group on Nanomaterials that extensively updated and extended Version 1.0. The UDS 2.0 contains 19 tables of detailed descriptors and their definitions that are directly applicable for reporting nanomaterials research results, identifying nanomaterials in regulations and standards, developing formats for nanoinformatics resources, specifying nanomaterials in commercial transactions, and other uses. Comments and suggestions are welcomed. Please send to nanomaterials@codata.org
