Resources for Developers
The following services, schemas, and data models are available for developers:
EarthChem REST Service
The EarthChem REST Search Service accepts GET string variables which determine search criteria. The target URL for the EarthChem REST Search Service is: http://portal.earthchem.org/restsearchservice
EarthChem WFS Service
The EarthChem WFS Service is a full transactional implementation of the OpenGIS Consortium’s Web Feature Server specification.
The following layers are available:
- Isotopes
- NobleGas
- RareEarth_Element
- StableIsotopes
- Trace_Element
- U-Series
- VolatileGas
- WR_Major_Element
The EarthChem WFS Service can be found at:
http://portal.earthchem.org/wfs/ows?service=wfs&version=1.0.0&request=GetCapabilities
EarthChem XML
The EarthChem Portal serves PetDB data published in a standard XML and served via XML-based web services. An XML schema has been developed as part of the EarthChem project to publish Geochemical data. The schema includes metadata such as location, reference, chemical data, and controlled vocabularies (ontologies) for validation.
Data Models
The EarthChem team have been involved in the development of data models such as the Observations Data Model 2 (ODM2) (Horsburgh et al. 2016). ODM2 forms the basis of EarthChem data syntheses, in part because of the flexibility to include both specimen-based and time series measurements.
The original PetDB data model is described in Lehnert et al. 2000.
