Seagrass EOV Data Package

An identifier for the set of information associated with a dwc:Event (something that occurs at a place and time). May be a global unique identifier or an identifier specific to the data set.

• required: true
• unique: true

An identifier for the broader dwc:Event that groups this and potentially other dwc:Events.

The geographic latitude (in decimal degrees, using the spatial reference system given in dwc:geodeticDatum) of the geographic center of a dcterms:Location. Positive values are north of the Equator, negative values are south of it. Legal values lie between -90 and 90, inclusive.

• required: true

The geographic longitude (in decimal degrees, using the spatial reference system given in dwc:geodeticDatum) of the geographic center of a dcterms:Location. Positive values are east of the Greenwich Meridian, negative values are west of it. Legal values lie between -180 and 180, inclusive.

• required: true

The ellipsoid, geodetic datum, or spatial reference system (SRS) upon which the geographic coordinates given in dwc:decimalLatitude and dwc:decimalLongitude are based.

• pattern: EPSG:[0-9]+

The horizontal distance (in meters) from the given dwc:decimalLatitude and dwc:decimalLongitude describing the smallest circle containing the whole of the dcterms:Location. Leave the value empty if the uncertainty is unknown, cannot be estimated, or is not applicable (because there are no coordinates). Zero is not a valid value for this term.

A Well-Known Text (WKT) representation of the shape (footprint, geometry) that defines the dcterms:Location. A dcterms:Location may have both a point-radius representation (see dwc:decimalLatitude) and a footprint representation, and they may differ from each other.

The standard code for the country in which the dcterms:Location occurs.

The date-time or interval during which a dwc:Event occurred. For occurrences, this is the date-time when the dwc:Event was recorded. Not suitable for a time in a geological context.

• required: true
• pattern: \d{4}-\d{2}-\d{2}(?:T\d{2}:\d{2}:\d{2}Z)?

A bibliographic reference for the resource.

An identifier for the set of data. May be a global unique identifier or an identifier specific to a collection or institution.

The name identifying the data set from which the record was derived.

One of a) an indicator of the existence of, b) a reference to (publication, URI), or c) the text of notes taken in the field about the dwc:Event.

A category or description of the habitat in which the dwc:Event occurred.

The name (or acronym) in use by the institution having custody of the object(s) or information referred to in the record.

An identifier for the institution having custody of the object(s) or information referred to in the record.

A legal document giving official permission to do something with the resource.

The greater depth of a range of depth below the local surface, in meters.

The lesser depth of a range of depth below the local surface, in meters.

A person or organization owning or managing rights over the resource.

The names of, references to, or descriptions of the methods or protocols used during a dwc:Event.

A numeric value for a measurement of the size (time duration, length, area, or volume) of a sample in a sampling dwc:Event.

The unit of measurement of the size (time duration, length, area, or volume) of a sample in a sampling dwc:Event.

An identifier for the set of information associated with a dwc:Event (something that occurs at a place and time). May be a global unique identifier or an identifier specific to the data set.

• required: true

• events.eventID

An identifier for the dwc:Occurrence (as opposed to a particular digital record of the dwc:Occurrence). In the absence of a persistent global unique identifier, construct one from a combination of identifiers in the record that will most closely make the dwc:occurrenceID globally unique.

• required: true
• unique: true

A string representing the taxonomic identification as it appeared in the original record.

• required: true

An identifier for the nomenclatural (not taxonomic) details of a scientific name.

• required: true
• pattern: urn:lsid:marinespecies\.org:taxname:[0-9]+

The specific nature of the data record.

• required: true
• enum: MaterialEntity, PreservedSpecimen, FossilSpecimen, LivingSpecimen, MaterialSample, Event, HumanObservation, MachineObservation, Taxon, Occurrence, MaterialCitation

A statement about the presence or absence of a dwc:Taxon at a dcterms:Location.

• required: true
• enum: present, absent

A brief phrase or a standard term (“cf.”, “aff.”) to express the determiner’s doubts about the dwc:Identification.

A list (concatenated and separated) of names of people, groups, or organizations who assigned the dwc:Taxon to the subject.

A person, group, or organization responsible for recording the original dwc:Occurrence.

A common or vernacular name.

The full scientific name of the kingdom in which the dwc:Taxon is classified.

The full scientific name of the phylum in which the dwc:Taxon is classified.

The full scientific name of the class in which the dwc:Taxon is classified.

The full scientific name of the order in which the dwc:Taxon is classified.

The full scientific name of the family in which the dwc:Taxon is classified.

The full scientific name of the genus in which the dwc:Taxon is classified.

The taxonomic rank of the most specific name in the dwc:scientificName.

An identifier for the set of information associated with a dwc:Event (something that occurs at a place and time). May be a global unique identifier or an identifier specific to the data set.

• required: true

• events.eventID

An identifier for the dwc:Occurrence (as opposed to a particular digital record of the dwc:Occurrence). In the absence of a persistent global unique identifier, construct one from a combination of identifiers in the record that will most closely make the dwc:occurrenceID globally unique.

• required: true

• occurrences.occurrenceID

An identifier for the dwc:MeasurementOrFact (information pertaining to measurements, facts, characteristics, or assertions). May be a global unique identifier or an identifier specific to the data set.

The nature of the measurement, fact, characteristic, or assertion.

• required: true
• pattern: ^arealExtent|percentCover|canopyHeight|shootDensity|shootLength|aboveGroundBiomass|belowGroundBiomass|depth|waterClarity|waterTemperature|salinity|sedimentGrainSize|epifaunaAbundance|fishAbundance|macroalgaeBiomass|macroalgaeCover|epiphyteDryMass|.*$

The units associated with the dwc:measurementValue.

• required: true

The value of the measurement, fact, characteristic, or assertion.

• required: true

The description of the potential error associated with the dwc:measurementValue.

A list (concatenated and separated) of names of people, groups, or organizations who determined the value of the dwc:MeasurementOrFact.

The date on which the dwc:MeasurementOrFact was made.

• pattern: \d{4}-\d{2}-\d{2}(?:T\d{2}:\d{2}:\d{2}Z)?

A description of or reference to (publication, URI) the method or protocol used to determine the measurement, fact, characteristic, or assertion.

An identifier for the measurementType (global unique identifier, URI). The identifier should reference the measurementType in a vocabulary.

An identifier for the measurementUnit (global unique identifier, URI). The identifier should reference the measurementUnit in a vocabulary.

An identifier for facts stored in the column measurementValue (global unique identifier, URI). This identifier can reference a controlled vocabulary (e.g. for sampling instrument names, methodologies, life stages) or reference a methodology paper with a DOI. When the measurementValue refers to a value and not to a fact, the measurementvalueID has no meaning and should remain empty.
