Soil data is crucial for environmental studies and analysis, but access to it and proper exchange formats and mechanisms are still poorly developed. The OGC Soil Data Interoperability Experiment (SoilIE), undertaken in the second half of 2015, had the objective of developing and testing a soil standard that harmonised existing standards defined in Europe and Oceania. During the SoilIE, participants from Europe, North America and Oceania mapped data in their soil databases to the SoilIE XML schema. Multiple OGC Web Feature Services (WFS) delivering soil observation data using the XML schema were established, along with OGC Web Processing Services to allow on-line derivation of new data. The SoilIE was successful with access to data in multiple clients from multiple soil data providers, each using different software configurations. The interoperability results will be presented along with next steps on progressing the SoilIE XML schema, RDF vocabularies, linked data and remaining major issues.
