Properties



MBGCommonTerms

verbatimModified
The date and time value of the modified term, recorded in the exact format that the data originator provided it, for purposes of audit trail, since OBIS-USA will convert this to ISO 8601:2004(E) for operational purposes.

Data Type string
Requiredfalse
associatedMetadata
Identifier(s) or url(s) that identify the reference copy (system of record) of metadata associated with the datasetID. OBIS-USA practice is to name the metadata file with the contents of the "datasetID" term, to make a durable connection between data and metadata.

eventDateTimeZone
The time zone of the observation event, expressed as +/- hh:mm offset from UTC. While time zone information can also be included in the full ISO 8601 expression in eventDate, time zone is stored here for reliable use in time and timeUncertainty calculations. (The term) time must be expressed in UTC.

eventDateRemarks
eventDateRemarks explains information about date and time that may not be evident in verbatim, ISO 8601, or nominal forms of the date and time. For example, date and time may include uncertainty, such as time of day left null because time was not recorded. However, data originators may be able to say that although time was not recorded, the observation is known to have been made between 8am and 5pm local time. eventDateRemarks can provide a concise explanation of this condition. eventDateRemarks can also provide explanation for how timeUncertainty was determined.

Data Type string

time
This term identifies a specific instant chosen to represent the date and time of the observation, in Coordinated Universal Time (UTC). Both date and time are specified in this term in order to facilitate some searches and services that require resolution of events to this level of precision in time. Some observation events occur with uncertainty at the level of minutes, hours, or even days or more. A nominal event date and time is determined, even for observations with date and time uncertainty, for web services to best represent the instant of the event. The companion term, timeUncertainty, defines an interval of uncertainty that quantifies precision to correspond to the precision the original data recorded. Methods for determining nominal time and uncertainty will be documented in metadata, and they can be explained (if concise) in the eventDateRemarks term.

latitude
The position of the observation north or south of the equator in decimal degrees. Latitudes north of the equator are positive and range to +90 degrees. Positions south of the equator are negative, and range to -90 degrees. This term is implemented in the OBIS-USA database as character data to preserve the exact information provided by the data originator, particularly the number of decimal places, that must be retained to remain true to the original information.

longitude
The position of the observation east or west of the prime meridian in decimal degrees. Positions west of the prime meridian are negative, and range to -180. Positions east of the prime meridian are positive, and range to +180. This term is implemented in the OBIS-USA database as character data to preserve the exact information provided by the data originator, because exact features such as the number of decimal places must be retained to remain true to the original information.

altitude
The altitude or elevation of the surface of the water, in meters above sea level, in which the observation was made. "altitude" is expressed as a single value rather than the min and max as in DwC. Work with a representative of the original data to determine what is the preferred way to represent single value and min/max, as necessary. This single value named "altitude" is required for ERDDAP and Climate and Forecast compatibility.

source
The Source term carries over from vOBIS, where it had been considered for discontinuation. However, it has proven useful for identifying literature as a source of biogeographic information, so it is retained in MBG for use at the record level when the occurrence record is derived from literature. Enter the literature citation in this term. This will be required when the basisOfRecord is "DerivedFromLiterature". Transition to the Darwin Core term for this purpose in MBG.

weightInKg
The recorded weight in kilograms of the individuals in the observation. Capture in metadata details about weight, such as what kind of weight (e.g., dry weight), calculation or estimation procedures, or other details applied in determining weight. This is in contrast to totalInSample, that can report the total in the original sample in cases of subsampling. In cases of subsampling, weightInKg will be the weight of the subject of this occurrence record, be it an individual or more than one individual total weight.

trackHomeRecord
trackHomeRecord identifies the single record and location to consider home for the individual or group identified by the individualID. trackHomeRecord assists determination that multiple records may be included in OBIS-USA, but only one should be counted to accurately assess the total number of individuals in OBIS-USA. trackHomeRecord will be determined according to practices approved by the data originator. For example, trackHomeRecord can be the first record, or a mid-point record based on time or geography, or determined by some other approved method. Values can be true, false, or null.

trackSequenceNumber
The combination of individuaID and the eventDate should capture information about multiple observations as well as the sequence of observations, representing the track covered by the individual. The sequence number term will be generated, in coordination with the data originator, as a series of ordinal integers. The purpose is either to cross-validate the sequence, or to accommodate missing information in a track (such as imprecise time stamps). The practice of adding this sequence number may prove to be unnecessary if track observation data is complete and verifiable.

samplingConditions
Information about the state of the sampling location, determined by external factors such as weather, water conditions, lighting and visibility, etc., at the time of the sampling event. Like samplingEffort, this term describes phenomena other than the method intended by the data collector in the samplingProtocol. The difference between samplingEffort and samplingConditions is that samplingConditions describes the state of the environment, and samplingEffort describes the actions of the sampler. More than one type of information about conditions can be concatenated into this term, delimited by semicolon. Contents in this term (either verbatim or by vocabulary) will be used consistently in a dataset and will be explained in metadata. More extensive discussion of sampling conditions may be provided in metadata as needed.

totalInSample
In cases where subsampling has been done and the data record represents a subsample, the totalInSample term contains information about the total quantity in the original sample, usually expressed as total count or weight, for example "Count=85" or "Weight=4.4kg". Specific details about how subsampling was done in relation to the total sample must be explained in samplingProtocol, and/or in metadata.

quantificationVocabulary
The names for derived values, referred to as quantification, can be drawn from a controlled vocabulary or vocabularies of quantification names. Or they can be reported using the verbatim name given by the data originator. Either the name of the controlled vocabulary or the word “verbatim” should be used in this term to record the level of control over names. Verbatim means the names are not using a controlled vocabulary other than the names assigned just as they are by the data originator. Either way, within a dataset, identifiers for quantification names must be used consistently and explained in metadata.

Data Type string
Requiredfalse
quantificationName
A name for a derived value or processed data about the occurrence, for example, "Biomass". The word used in this terminology for such information is "quantification", rather than "abundance", because the word "abundance" may already be associated with specific, rather than general, practices of quantification in biology. In this example, biomass would not be obtained at survey time, rather biomass would be calculated from input data that was obtained at survey time, combined with a biomass calculation methodology. This term is used along with companion terms for quantification value, units, uncertainty, method, and determination details. It is suggested that names for derived values be more specific than "Biomass", because many institutions will develop biomass information using diverse methods. Suggested practice is to include some more specific reference(s) in the quantification name, such as institution, survey, date or other specifics. For example, "Biomass-PIFSC-2011", and explain the name and method of calculation in metadata.

quantificationUncertainty
An estimate of the uncertainty, positive and negative (+/-) offset of the stated value, that expresses the uncertainty of the value as calculated and reported. This can be reported in the units of the quantification, or as a percentage. Note that the expression in this term can combine both accuracy and precision considerations to a more general estimate uncertainty; hence the slightly different name for this term compared to the Darwin Core (dwc) reference term.

quantificationMethod
A reference to the method used to determine the quantification. This will be different from the method used to make the observation of biological occurrence; it will be the companion calculation method that followed the observation method. Quantification information is expected to be useful only if method is sufficiently documented, so this term is vitally important for use of quantification terms for derived values. This term can contain a code or other abbreviated reference to a method. In all cases quantificationMethod should be explained in metadata and supporting publications or related resources identified.
