Lite Schemas

GeoSciML-Lite and EarthResourceML-Lite (ERML-Lite) are simplified schemas that take the form of a flat table of attributes (conformant to OGC Simple Features Level-0 profile). These were previously called GeoSciML-Portrayal and EarthResourceML-Portrayal.

GeoSciML-Lite

The full specification for GeoSciML-Lite is in the GeoSciML standard. OneGeology itself does not currently make direct use of data using these schemas but the age and lithology URI columns in GeologicUnitView are those that an SLD enabled WMS needs to provide for the age and lithology highlighting functionality to work. These schemas do, however, provide a method to exchange simple interoperable data without supporting complex features that may be more easily achievable and that can help qualify for a 4 star accreditation.

There are seven GeoSciML-Lite views descibed in the 4.1 standard, these are: GeologicUnitView, ShearDisplacmentStructureView, ContactView, BoreholeView, SiteObservationView, GeologicSpecimenView, GeomorphologicUnitView. Below we lay out what is expected of the views for those features we think that many geological survey organizations will be able to support.

Generally across all GeoSciML-Lite views, missing values should be specified using OGC nil values http://www.opengis.net/def/nil/ogc/0/ as below:

above detection range (AboveDetectionRange)
Value was above the detection range of the instrument used to estimate it.
below detection range (BelowDetectionRange)
Value was below the detection range of the instrument used to estimate it.
inapplicable
There is no value
missing
The correct value is not readily available to the sender of this data. Furthermore, a correct value may not exist
template
The value will be available later
unknown
The correct value is not known to, and not computable by, the sender of this data. However, a correct value probably exists
withheld
The value is not divulged

Alternatively you could use INSPIRE defined void reaons http://inspire.ec.europa.eu/codelist/VoidReasonValue/

In the below tables describing the features, Bold property names indicate required properties., whilst properties of type _uri are defined as xs:string in the GeoSciML-Lite 4.1 schema, to be conformant with GML SF-0, the intention is that these strings SHALL BE absolute URI's.

ContactView features

These features provide a simplified view of GeoSciML Contact Features. In GeoSciML terms this will be an instance of a MappedFeature with key property values from the associated ContactFeature summarized in text (data type xs:string) fields, and properties suffixed with ‘_uri’ that contain URIs referring to other resources, for example controlled concepts in published vocabularies.

Elements in ContactView mapped feature scheme

Name Implementation data type Notes
identifier xs:string Globally unique identifier for the individual feature. Recommended practice is that this identifier be derived from the primary key for the spatial objects in the source data in case information needs to be transferred from the interchange format back to the source database. This identifier is analogous to the identifier for a GeoSciML MappedFeature.
name xs:string Display name for the Contact. Examples: ‘depositional contact’, ‘unconformity’, ‘Martin-Escabrosa contact

contactType xs:string Text label specifying the kind of surface separating two geologic units including primary boundaries such as depositional contacts, all kinds of unconformities, intrusive contacts, and gradational contacts, as well as faults that separate geologic units. Ideally this would be the preferred label for the concept identified by contactType_uri

positionalAccuracy xs:string Preferred use is a quantitative value defining the radius of an uncertainty buffer around a MappedFeature, e.g. a positionAccuracy of 100 m for a line feature defines a buffer polygon of total width 200 m centered on the line. Some other text description that quantifies position accuracy may be provided, e.g. a term from a controlled vocabulary. Vocabulary used should be described in the dataset metadata.
source xs:string Text describing feature specific details and citations to source materials, and if available providing URLs to reference material and publications describing the geologic feature. This could be a short text synopsis of key information that would also be in the metadata record referenced by metadata_uri.
contactType_uri xs:string URI referring to a controlled concept from a vocabulary defining the Contact types. Mandatory property - if no value is provided then an URI referring to a controlled concept explaining why the value is nil must be provided.
The current CGI controlled vocabulary is: http://resource.geosciml.org/classifier/cgi/contacttype
There is no INSPIRE specific controlled vocabulary for contact type.
OneGeology-Europe services applied one of the following CGI vocabulary terms:
impact_structure_boundary, volcanic_subsicence_zone_boundary, glacial_stationary_line
specification_uri xs:string URI referring to the GeoSciML Contact feature that describes the instance in detail. Mandatory property - if no value is provided then an URI referring to a controlled concept explaining why the value is nil must be provided.

This is the only element with complex content, and must contain a GML geometry that is valid for the Geography Markup Language (GML) simple features profile (OGC 06-049r1.). The shape value will generally be provided by GIS software, and will need no user input.
Other attribute(s) A placeholder allowing any user-defined attributes to be delivered in addition to those specified above.

ShearDisplacementStructureView features

These features represent faults and ductile shear zones. In GeoSciML terms they are instances of MappedFeature with key property values from the associated ShearDisplacementStructure feature summarized in text fields (data type xs:string) and fields containing identifiers (URI) for fault type, deformation style, movement type, geologic age, and a formally-encoded (ideally in GeoSciML) specification for interoperability. The latter are the properties suffixed with ‘_uri’ and will contain URIs referring to other resources, for example controlled concepts in published vocabularies.

The concept of ‘Shear displacement structure’ includes all brittle to ductile style faults or ductile shear zones along which displacement has occurred, from a simple, single ‘planar’ brittle or ductile surface to a fault system comprising multiple strands of both brittle and ductile nature. Because this feature class is constrained to have a linear geometry, it is limited to representing shear displacement structures that are considered single surfaces at the scale of portrayal.

GeologicUnitView features

GeologicUnitView features represent outcrops of a particular geologic unit, typically with polygon geometry. The properties of these features provide a simplified view of information associated with GeoSciML GeologicUnit features. A geologic unit in this context is an identifiable body of material within the Earth. GeologicUnitView features are instances of GeoSciML MappedFeature with property values from the associated GeologicUnit specifier summarized in text fields for human data consumers, and with fields containing standard identifiers for geologic unit type, representative lithology, and geologic age. The specification_uri property identifies a description resource specific to the geologic unit cropping out in the extent of the polygon (or other) geometry of the feature. The specification_uri should dereference to yield a formally-encoded representation of the geologic unit, ideally in GeoSciML for interoperability. Properties populated by identifiers are suffixed with ‘_uri’ and contain URIs referring to other resources, for example controlled concepts in published vocabularies.

Commodity rank is based on the total endowment in an EarthResource, i.e. (cumulated) past production + reserves (not including past production) + resources, or if the deposit has never been exploited, reserves + resources. A statistical comparison with a large set of deposits throughout the world enables the determination of the deposit as class A (very large), B (large), or C (medium-sized) for a particular commodity.

Synonyms: Ore Reserve; Coal Reserve (s); Diamond (or gemstone) Ore Reserve; Mineral Reserves (not preferred, should be stated that used to mean the same as JORC’s Ore Reserve); Mineable production estimates. Text string data type so units of measure can be included in value. eg, 1.23 Mt @ 3.0 g/t Au
