A single electrode reading within an in-situ resistivity test: the array geometry,the resistance measured and the apparent resistivity computed from it. Theseparation geometry is exactly one of three forms, selected by the procedure'sdiggs:arrayType: a Wenner array gives diggs:electrodeSpacing alone, a Schlumbergerarray the pair diggs:currentElectrodeSeparation anddiggs:potentialElectrodeSeparation, and a dipole-dipole array the pairdiggs:dipoleLength and diggs:nFactor. Independently of that form, a traverse alsogives diggs:readingLocation and an azimuthal survey diggs:orientation.
Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
