Abstract
Metadata is important when considering online data and information management. Metadata allows the data and information to be summarized within the context and language of the content theme. As such, it is important for searches and providing relevant information to the client. A comparison of metadata standards was conducted with emphasis on the standards capacity for geospatial metadata. Five standards were considered in detail: Dublin Core, GILS, GCMD, FGDC and ISO 19115. Each standard was considered from the standpoint of the required minimum information set and the geospatial information set. The usefulness of the various standards to geospatial data and information is considered within the context of ocean environmental data. Results indicate the FGDC standard is a complete and succinct metadata standard, with sufficient scope to be applicable to a wide variety of datasets.
