Field Name: Institution Code Data Type: Text OBIS Field? Yes Description: 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). Field Name: Collection Code Data Type: Text OBIS Field? Yes Description: A unique alphanumeric value which identifies the collection within the institution (e.g. "FishBase"). Field Name: Field Number Data Type: Text OBIS Field? Yes Description: A "number" (really a string) created at collection time to identify all material that resulted from a collecting event, e.g. station or sample numbers. Field Name: Catalog Number Data Type: Text OBIS Field? Yes Description: 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. Field Name: Year Collected Data Type: Integer OBIS Field? Yes Description: The year (expressed as an integer) the sample/observation/record event occurred. The full year should be expressed (e.g. 1972 must be expressed as "1972" not "72"). Must always be a four digit integer. Where the event covers a range of values for year, indicates the mid-point of that range. Field Name: Month Collected Data Type: Integer OBIS Field? Yes Description: The month of year the sample/observation/record event occurred in the field. Where the event covers a range of values for month, indicates the mid-point of that range. Leave blank if even spans multiple years. Field Name: Day Collected Data Type: Integer OBIS Field? Yes Description: The day of the month the sample/observation/record event occurred in the field. Possible value ranges from 01..31 inclusive. Where the event covers a range of values for day, indicates the mid-point of that range. Leave blank if event spans multiple months. Field Name: Time of Day Data Type: Decimal OBIS Field? Yes Description: The time of day a specimen was collected expressed as decimal hours from midnight (e.g. 12.0 = mid day, 13.5 = 1:30pm). Field Name: Longitude Data Type: Decimal OBIS Field? Yes Description: The longitude of the location from which the specimen was collected or in which the sample/observation/record event occurred. This value should be expressed in decimal degrees (East & North = +; West & South = -). GPS-derived data should be referenced to the WGS/84 datum. Field Name: Latitude Data Type: Decimal OBIS Field? Yes Description: The latitude of the location from which the specimen was collected. This value should be expressed in decimal degrees (East & North = +; West & South = -). GPS-derived data must use the WGS 84 geodetic reference system (http://www.wgs84.com/). Field Name: Minimum Depth Data Type: Decimal OBIS Field? Yes Description: The minimum distance in meters below the surface of the water at which the collection/record was made; all material collected was at least this deep. Positive below the surface, negative above (e.g. collecting above sea level in tidal areas). Field Name: Maximum Depth Data Type: Decimal OBIS Field? Yes Description: The maximum distance in meters below the surface of the water at which the collection/record was made; all material collected was at most this deep. Positive below the surface, negative above (e.g. collecting above sea level in tidal areas). Field Name: Basis of Record Data Type: Text OBIS Field? Yes Description: An abbreviation indicating whether the record represents an observation (O) (this can include a visual observation, a survey catch, a commercial landing record, etc), a collected living organism, such as a tree in a botanical garden (L), a specimen in a collection/museum (S), a collected germplasm/seed (G), a photo (P), or derived from literature, where original basis unknown (D). Field Name: GMBIS Taxa Code Data Type: Integer OBIS Field? No Description: Field Name: Scientific name Data Type: Text OBIS Field? Yes Description: The full name of lowest level taxon the Cataloged Item can be identified as a member of; includes genus, specific epithet, and subspecific epithet (zool.) or infraspecific rank abbreviation, and infraspecific epithet (bot.) Use name of suprageneric taxon (e.g., family name) if Cataloged Item cannot be identified to genus, species, or infraspecific taxon. Field Name: Kingdom Data Type: Text OBIS Field? Yes Description: The kingdom to which the organism belongs. Field Name: Phylum Data Type: Text OBIS Field? Yes Description: The phylum (or division) to which the organism belongs. Field Name: Class Data Type: Text OBIS Field? Yes Description: The class name of the organism. Field Name: Order Data Type: Text OBIS Field? Yes Description: The order name of the organism. Field Name: Family Data Type: Text OBIS Field? Yes Description: The family name of the organism. Field Name: Genus Data Type: Text OBIS Field? Yes Description: The genus name of the organism. While this field is highly recommended when the identification to genus is known, it should not be filled in if the identification cannot be made down to genus with confidence. Field Name: Species Data Type: Text OBIS Field? Yes Description: The specific epithet of the organism. Field Name: Common Name Data Type: Text OBIS Field? No Description: Field Name: Sex Data Type: Text OBIS Field? Yes Description: The sex of a specimen or collected/observed individual(s). The domain should be a controlled set of terms (codes) based on community consensus. Proposed values: M=Male; F=Female; H=Hermaphrodite; I=Indeterminate (examined but could not be determined; U=Unkown (not examined); T=Transitional (between sexes; useful for sequential hermaphrodites); B = Both Male and Female. Field Name: Observed Individual Count Data Type: Decimal OBIS Field? Yes Description: The number of individuals (abundance) found in a collection/record event. Field Name: Observed Weight Data Type: Decimal OBIS Field? Yes Description: The total biomass found in a collection/record event. Expressed as kg. Field Name: Date Last Modified Data Type: DateTime OBIS Field? Yes Description: 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.
