About the AMD
The Antarctic Master Directory is the largest collection of Antarctic data set description in the world, holding over 7700 dataset descriptions from 25 countries. 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.
Benefits of metadata
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:
- Facilitate access to data
- Facilitate interdisciplinary research
- Maximise the use of data
- Disseminate knowledge about Antarctic scientific programs
- Avoid duplication of research and data collection
- Improve efficiency of Antarctic scientific data management
- Facilitate new research through access to existing Antarctic scientific data
- Provide a tool for support and decision making for Antarctic operators and scientists
- Improve cooperation and interoperability between disciplines and Treaty nations
- Allow better oversight of national programmes
- The metadata standard (DIF)
All metadata should adhere to certain standards to facilitate information search and retrieval.
The IPY Data System also has a metadata profile.
The AMD host, GCMD, provides extensive information on the relevant standards:
