4. Avoid data duplication Date Last Modified Optional for OBIS (Required for GBIF/Darwin Core servers) DateTime The date and time the record was last modified. Format: ISO 8601 compliant stamp in UTC(GMT) when the record was last modified. Example: "November 5, 1994, 8:15:30 am, US Eastern Standard Time" would be represented as "1994-11-05T13:15:30Z" (see W3C Note on Date and Time Formats - http://www.w3.org/TR/NOTE-datetime). While this field is required by the Darwin Core, OBIS can accommodate datasets without it. Institution CodeRequiredText A "standard" code identifier that identifies the institution to which the collection belongs, if there is one. Use the code that is "standard" in your discipline, if there is one (no global registry exists for assigning institutional codes). If not, use a short version of the name of the institution. (e.g. "NMNH" for Smithsonian National Museum of Natural History or "Duke" for Duke University). Collection CodeRequiredText A unique alphanumeric value which identifies the collection within the institution (e.g. "FishBase"). Catalog Number RequiredText / Numeric A unique alphanumeric value which identifies an individual record within the collection, i.e. the key. It is recommended that this value provides a key by which the actual specimen/observation can be identified. If the specimen/observation has several items such as various types of preparation, this value should identify the individual component of the specimen Same standards (DwC) Digital Object Identifier (DOIs)

5. GBIF & OBIS Memorandum of Cooperation (in development) Maximize the quantity, quality, completeness and fitness for use of marine biodiversity data accessible through OBIS and GBIF Data standards (DWC) Technology (IPT) Quality control and fitness for use Training

6. OBIS GBIF GBIF has less data types (no abundance, no depth, no taxon LSIDs,…) GBIF has no mandatory QC steps No identifier for marine datasets, nor technical solution to avoid data duplication OBIS GBIF So far: ideally marine data should flow from OBIS to GBIF
