A spatial association can bemade, but an explicit association by this property is definitive,should be used in preference to a spatial comparison, and governswhere the two disagree. The positional test, of the column'sreferencePoint against the featureExtent of the platform, remains afallback where this element is absent, but it is only an inference:platform extents may overlap where a structure's platform is drawnover a residual "remaining area" platform without being punched outof it, and a column head within centimeters of a shared boundary isdecided by rounding rather than intent. The reference statesmembership, asserted by the member, like the inheritedsamplingFeatureGroupRef. Given by reference only.
The gml:identifier value of the referenced feature, as a fully qualifiedvalue. It gives an alternative to the gml:id in xlink:href for findingthe referenced feature, mainly to reference a feature by a globallyunique identifier and where naming conflicts occur with gml:id whenaccessing data in external files.

How the ground was handled as this column was formed: fulldisplacement, partial displacement or replacement. It is the primaryclassifier: a displacement technique generates no spoil anddensifies the surrounding ground, while a replacement techniqueremoves soil, so the quality-control data a rig can produce and theacceptance evidence that can be asked for both follow from it. It isorthogonal to columnType, and constrained against it: columnTypenames the technique and this names what that technique does to theground, but they are not independent (a continuous flight augercolumn cannot be full displacement), so each columnType.xml entrydeclares the families it is compatible with through aconditionalElementXpath on its Occurrence. That check is performedby dictionary-validation.xsl, not by this schema, because XSD cannotexpress a correlation between sibling values; as a consequence,stating columnType without this element fails dictionary validation,so in practice the two travel together. The ri prefix marks thatthis element is bound to the rigid inclusion list; installationmethod is a concept other DIGGS domains will want under their ownvocabularies. Values come from the enumerated list, or "Other: xx",where xx is a user-defined term whose meaning differs from everylisted value (not a synonym of one).

The position this column actually occupied in the installationorder, counting from 1; the as-built counterpart of the plannedorder stated by a diggs:DesignProductionSequence. It is recordedrather than derived, because the actual order is not recoverablefrom whenConstructed (optional, thinly populated, and a timestampanswers when rather than in what order, which matters where severalrigs work concurrently) or from the column's name. Comparing it withthe planned order shows whether a specified sequence was followed,and it is the as-built side against which a minimum age or minimumspacing to fresh concrete, specified as a diggs:ClearanceConstraint,is evaluated.

The elevation of the ground surface, or of the working platformwhere one is present, at this column. A rigid inclusion conflatesthe drilled hole and the grout column into one sampling feature, andthe column takes precedence for geometry: the centerLine runs fromthe column head to the column tip, not from ground level to the tip.Depths recorded while drilling (measurement-while-drilling data, andevents on the construction activity) are measured from the ground orplatform datum the rig works from, and this property relates thetwo; without it, drilling-time depths cannot be placed on thecolumn. Because it is a position, not a length, it may be stated inwhichever frame it was measured: a one-dimensional position in avertical CRS, a one-dimensional position in this column's own linearreferencing system, or a full three-dimensional position. PopulateuomLabels so the unit is readable without resolving the CRS. Itcorresponds to the property of the same name ondiggs:AbstractPileType.

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.
