Joint INIS/ETDE Technical Committee Meeting 2007 recommendation:
“appreciated the work of the INIS Secretariat to analyse the usage of the INIS
Database, strongly supported the continuation of the project to learn about
the Database content usage along with other usage aspects, and
recommended that the results be made available to all participants at the JTCM
as soon as it is ready and be presented at the 34th Consultative Meeting of ILOs
in 2008”
