WALIS Metadata Policy
Metadata describes spatial datasets and through publication on Interragator+, the metadata ensures spatial data created within WA can be found and accessed.
The State's land information holdings represent a considerable resource for government, the community and the private sector. To ensure that this resource is effectively used, it is vital that people are aware of what information is available. The key to this is metadata.
Metadata is data about data. It describes the content, format, quality, currency and availability of data. Through the metadata policy WALIS recognises the importance of metadata in promoting the availability of land information in Western Australia.
Metadata for land and geographic information is required for a range of purposes and includes:
-
detailed information about data collection methods, integration and analysis techniques applied to various components of source data to support the preparation of scientific reports;
-
information about the accuracy of source datasets, processing history, and archival procedures to effectively manage and utilise data within custodian organisations;
-
information about projection specifications, scale, and a data dictionary to accompany data transfers to other organisations;
-
adequate descriptions of the content, quality and geographic extent of datasets so potential users of existing data can assess its suitability for other purposes; and
-
summary descriptions of content and quality as well as contact information for inclusion in directory systems.
The purpose of this policy is to define the metadata requirements for inclusion in the directory systems so that potential users are aware of existing data and can assess its suitability for other purposes and to accompany data transfers to other organisations.
