Abstract: In order to move and transform the archival description to encoded metadata description, this paper puts forward a metadata model for the multi-entity and multi-level archival description of marine geological raw records, physical samples and final reports. Schemas for metadata content, format and style sheet implementation are also presented. Domestic and international standards for both archival description and archival metadata are comprehensively referenced, based upon the present content characteristics as well as arrangement systems of marine geological records. Marine geological information resources are expected to be served widely and shared well in the future.
