OceanDocs and Metadata standards Support of DC (Qualified), MODS, AGRIS AP, in the future also Marine XML Use of AGRIS AP facilitate –the integration of the developments in Agris DSpace –Availability through FAO search engines Specific metadata fields: –ASFA keywords –ASFA Journal list Aquatic Commons and metadata standards: Necessity of an agreement. Use of OAI, but also of other protocols (e.g. SRU/W)
