What is GeoSciML?
From the CGI-IUGS website:
GeoSciML is an XML–based data transfer standard for the exchange of digital geoscientific information. It accommodates the representation and description of features typically found on geological maps, as well as being extensible to other geoscience data such as drilling, sampling, and analytical data. GeoSciML provides a standard data structure for a suite of common geologic features (eg, geologic units, structures, earth materials) and artefacts of geological investigations (eg, boreholes, specimens, measurements). Supporting objects such as the geologic timescale and vocabularies are also provided as linked resources, so that they can be used as classifiers for the primary objects in the GeoSciML standard.
The latest version of the specifications of that joint CGI-IUGS and OGC standard can be found here: https://docs.ogc.org/is/16-008/16-008.html
