5. Maris Web Services  A Web Service interface to the EDMO catalogue (SeaDataNet organisation address book) has been developed by Maris  Documentation available at: http://seadatanet.maris2.nl/ws/ws_edmo.asmx  WSDL available at http://seadatanet.maris2.nl/ws/ws_edmo.asmx?wsdl

6. Web Service Plans Web Services provide an excellent technical solution for distributed data systems Metadata or data access service is deployed at each node Applications simply poll each instance of the service Service client code can be embedded into any kind of application – web browser display, data visualisation tool, numerical model and so on Therefore well-suited to the needs of SeaDataNet

7. Web Service Plans The SeaDataNet Technical task Team has already decided to post Web Services as interfaces to the metadata repositories Once we develop the design architecture I am certain web services will be developed for AAA (security) and data delivery
