The AMD is the central directory system containing all Antarctic data set descriptions gathered by NADCs. It is hosted by the Global Change Master Directory (GCMD) of the CEOS-IDN network to minimise duplication of resources and metadata.
In addition to the AMD portal, the GCMD has an IPY portal which highlights data that have been collected over the International Polar Year.
National data directories are a useful tool for Antarctic scientists and organisations. Collecting data set descriptions is not easy; even on a national scale, it requires a strong commitment. On-going support from managers of national Antarctic programmes is required.
The benefits that access to the AMD provides to national programmes are:
All metadata should adhere to certain standards to facilitate information search and retrieval.
The IPY Data System also has a metadata profile.
GCMD has provided a short tutorial on how to use docBUILDER, the metadata entry tool for the Antarctic Master Directory. If you want to add metadata to the AMD you need an account; you can contact the GCMD User Support Office (email@example.com) to obtain a registration name and pass code.
The GCMD maintains various statistics on the usage of the AMD.
