Module Documentation: eml-coverage
Back to EML Contents
The eml-coverage module contains fields for describing the coverage of a resource in terms of time, space, and taxonomy. These coverages (temporal, spatial, and taxonomic) represent the extent of applicability of the resource in those domains.

Element Definitions:

geographicCoverage
Content of this field: Description of this field:
Type: GeographicCoverage
Attributes: Required?: Default Value:

Description:
Geographic Coverage is a container for spatial information about a project, a resource, or an entity within a resource. It allows a bounding box for the overall coverage (in lat long), and also allows descriptin of arbitrary polygons with exclusions.
Example:
Please see the individual sub fields for specific examples.
temporalCoverage
Content of this field: Description of this field:

Derived from: TemporalCoverage (by xs:extension)

Elements: Required?: How many:
Attributes: Required?: Default Value:

Description:
This field specifies temporal coverage, and allows coverages to be a single point in time, multiple points in time, or a range of dates. Dates can be expressed in tems of both calander dates and geologic dating systems.
Example:
Please see the individual sub fields for specific examples.
taxonomicCoverage
Content of this field: Description of this field:

Derived from: TaxonomicCoverage (by xs:extension)

Elements: Required?: How many:
Attributes: Required?: Default Value:

Description:
Taxonomic Coverage is a container for Taxonomic information about a project, a resource, or an entity within a resource. It includes a list of species names (or higher level ranks) from one or more classification systems.

calendarDate
Content of this field: Description of this field:
Type: xs:date
Attributes: Required?: Default Value:

Description:
The calendar date field is used to express a date, giving the year, month, and day. The format should be one that complies with the International Standards Organization's standard 8601. The recommended format for EML is YYYY-MM-DD, where Y is the four digit year, M is the two digit month code (01 - 12, where January = 01), and D is the two digit day of the month (01 - 31).
Example:
2001-01-01 , which is January 1st, 2001.
time
Content of this field: Description of this field:
Type: xs:time
Attributes: Required?: Default Value:

Description:
The time field is used to express the hour (and optionally minute, or minute and second) of the day for an event, and should comply with the International Standards Organization's standard 8601. The recommended format for EML is hh:mm:ssTZD, where hh is the two digit hour of the day, mm is the two digit minute of the hour, and ss is the two digit second of the minute. TZD stands for Time Zone Designator which is used to handle time zone offsets. Times may be expressed in two ways: 1) UTC (Coordinated Universal Time, also known as Greenwich Mean Time, or GMT), with a special UTC designator ("Z"), 2) local time, together with a time zone offset in hours and minutes. A time zone offset of "+hh:mm" indicates that the date/time uses a local time zone which is "hh" hours and "mm" minutes ahead of UTC. A time zone offset of "-hh:mm" indicates that the date/time uses a local time zone which is "hh" hours and "mm" minutes behind UTC.
Example:
1) 08:31:22Z , which means eight thirty one and 22 seconds in the morning at Coordinated Universal Time (Greenwich Mean Time). 2) 14:06:09-08:00 , which means six minutes, nine seconds past two o'clock p.m., Pacific Standard Time (which is offset eight hours behind UTC)

A sequence of (
timeScaleNameOptionalMultiple Times
timeScaleAgeEstimateOptionalMultiple Times
timeScaleAgeUncertaintyOptionalMultiple Times
timeScaleAgeExplanationOptionalMultiple Times
timeScaleCitationOptionalMultiple Times
)
Attributes: Required?: Default Value:

Description:
A name, code, or date describing an event or period in an alternative time scale, for instance as an absolute date calculated using a named dating method, or as a relative date that is drawn from stratigraphy or biostratigraphy. Calendar dates as provided in the ISO 8601 dating system used in the standard CSDGM are not adequate to describe geologic time periods. Absolute geologic time is usually measured in millions of years before present, but may use different units and relative base times. Relative geologic time is measured by subdivisions of the earth's geology. in an order based upon relative age, most commonly, vertical or stratigraphic position. The actual dating systems used in geologic studies often tie relative times measured through stratigraphy or biostratigraphy to a particular absolute time using radioisotope dating techniques, among others. As these methods for absolute dating have improved, the estimates of the dates for strata have changed, consequently, it would be inaccurate to record absolute dates in situations where relative dates were measured. This structure is provided as an optional alternative to the standard calendar dates provided by ISO 8601.
Example:
Please see the individual sub-fields for specific examples.
timeScaleName
Content of this field: Description of this field:
Type: xs:string
Attributes: Required?: Default Value:

Description:
Name of a recognized alternative time scale. This includes 'Absolute' as the name of the time scale for measuring geologic dates before the present and names of geologic dating systems that are arrangements of symbols or names in order of relative geologic time.
Example:
'Absolute', 'Geomagnetic Polarity Time Scale', 'International Geological Time Scale', 'Oxygen-Isotope'
timeScaleAgeEstimate
Content of this field: Description of this field:
Type: xs:string
Attributes: Required?: Default Value:

Description:
Either an absolute date or a relative age name describing an event or period in an alternative time scale such as the Geologic Time Scale.
Example:
For example, '300 Ma' (300 million years before present) is a Geologic_Age_Estimate based on the Absolute Geologic_Time_Scale, 'C28r' is a chron name from the Geomagnetic Polarity Time Scale, and 'Maastrichtian' and 'Jurassic' are names from the International Geological Time Scale. Since different relative geologic time scales are often not aligned, multiple geologic dates may need to be specified. For example, the Geomagnetic Polarity Time Scale chron 'C29r', at the K/T boundary lies in both the 'Maastrichtian' and the 'Danian' stages from the International Geological Time Scale, thus if you were documenting this event using the International Geological Time Scale, both 'Maastrichtian' and 'Danian' should be included here.
timeScaleAgeUncertainty
Content of this field: Description of this field:
Type: xs:string
Attributes: Required?: Default Value:

geographicDescription
Content of this field: Description of this field:
Type: xs:string
Attributes: Required?: Default Value:

Description:
A geographic extent description is especially important when the extent of the data set is not well described by the "Bounding_Rectangle_Coordinates", or in the case of data which are not specifically geospatial, to provide a geographic setting for the item being documented. Assuming the "Bounding_Rectangle_Coordinates" do not adequately describe the extent of the data set, the discrepancy can be identified and described in this data element. If the item being documented is not specifically geospatial, the "Bounding_Rectangle_Coordinates" can define a general polygon, such as a rectangle around a country, with this "Description_of_Geographic_Extent" element containing a disclaimer concerning the "Bounding_Rectangle_Coordinates" and/or further detail concerning the geographic area of concern for the item being documented. For example, a study of the diseases of salmon may not have a specific geographic extent associated with it, but the salmon involved in the study were collected in Washington and Oregon states, thus the "Bounding_Rectangle_Coordinates" might form a general rectangle around the states of Washington and Oregon, but the "Description_of_Geographic_Extent" might describe the fact that the extent within Washington and Oregon included only certain rivers within those states. This data element differs from the standard data element "Place_Keyword" in that it allows a free text description of the geographic extent, rather than just a list of words or phrases useful as an index of location names associated with the data set.
Example:
Examples include, "Manistee River watershed", "extent of 7 1/2 minute quads containing any property belonging to Yellowstone National Park", or "ponds and reservoirs larger than 2 acres in Jefferson County, Colorado". This is especially important when the extent of the data set is not well described by the "Bounding_Rectangle_Coordinates".
