9. NTLIS Metadata Tool http://www.ntlis.nt.gov.au/forum/ntlis_documents/ntlis-metadata-tool/  ANZLIC profile of the ISO standard –(Hopefully) compatible with GIS software of the future  Web based, free to use by government and non government custodians  Data dictionary  Metadata forms a spatial dataset itself !  User feedback..

10. NTLIS Spatial Data Broker: Development  Currently in development –aiming for 4 th quarter 2007 release  Allows non-government users access to the existing ILIS Maps Spatial Data Download –vector data only  Users must have pre-arranged data license agreement (and payment) for restricted datasets  Custodians must have satisfied the Spatial Data Accessibility checklist for datasets (see Forum)

11. NTLIS Spatial Data Broker: Development  Data must be in a dissemination database  Custodians control access –role based authentication: ILIS –layers, attributes, polygon extent  End users control output: –format, projection, extent  ANZLIC / ISO 19139 metadata inclusion  Logging of who downloads what  Data license awareness –renewal reminders  Auto downloader –allows users to schedule downloads –used by NTLIS web applications

12. NTLIS Spatial Data Broker: Architecture

13. On the Horizon..  Better documentation of data: data dictionaries  More data in the dissemination databases  Production deployment of Spatial Data Broker –register your interest !
