This online Content Management System enables Sea-Search partners to check and to upgrade their national entries in the central Organisations Database. This contains addresses and profiles of all Data Holding Centres, Research Institutes, Monitoring Agencies, Data Originators, and Sea-Search Collating Centres, that are registered in one or more of the Sea-Search directories (EDMED - data sets, EDMERP - research projects, EDIOS - observing stations/ systems, and CDI - data). It also contains the codes in use in relation to EDMED, EDMERP, EDIOS and CDI-directories (still coming: CSR). A Sea-Search partner can only maintain its national entries, which includes editing of existing entries and possible activating - de-activating. The objective is to improve the address quality and the look & feel of the Organization profiles by including logo's, improving text layout, including illustrations etc..and to include geographical positions of Organizations to support the Geographical User interface (http://www.sea-search.net/edmo). Instructions, background info and principles of updating can be found at: www.sea-search.net/organisations. BODC and MARIS have a master log in for the CMS and can oversee and edit all entries, including codes, and have additional functionality for adding New records and Deleting existing entries, in case of duplicates.
