    revised May 20162016, August 2017
    Variables can be designated as having the "coordinate" data type, making them distinctive from other types and appropriate for integrating with other built-in mapping features. Variables of this type expect an X, a Y, and an optional Z, decimal value, formatted as X, Y, Z on data entry.
    Here, for example, is a variable used to indicate the Findspot of an item. Note that the (x, y, z) notation is not required, but is used by convention as a naming strategy for variables of this type.

    Items included in query-based mapping will know how to plot their coordinate data automatically.
    Point Labels
    As of the summer of 2017 coordinate-style points can have associated labels. A label can be any character string that you wish to associate with that point. Here we have a code entered into the Total Station when the point was shot in the field; it represents a "Bottom" elevation of a Pottery pail. This label might be noted on the excavator's top plan or in the total-station's file of points. Being able to retain the label on the point that was captured as a reference within OCHRE is a helpful option.

    Coordinate Systems
    In the absence of a specified coordinate system, a geographic coordinate system (GCS) based on the World Geodetic System (WGS) 1984 datum is assumed. In this case longitude, latitude, and elevation would represent the x, y, and z coordinates respectively. This is the same reference system used by the Global Positioning System (GPS).

    One of our archaeology projects counts and weighs the Pottery body sherds according to common ware types found at the site. Each ware type that is tracked is inserted as a sub-item within the Pottery Pail item listing the Quantity and Weight of the representative pot sherds. A separate sub-item is used to tally and weigh the Diagnostic sherds.

    Notice that the resulting aggregate Value is displayed in a highlight color and is read-only; this is because the value is derived and therefore not editable.

    A Concatenation Formula may also contain any number of variables linked in (using the hyperlink operator) from the Taxonomy. The value of the linked-in variable, as found on the item to which the formula is applied, or as found on any of its ancestors (if not found on the item itself), is substituted in for the linked-in variable.

    This Variable, called Auto-label C#, is then specified as an auto-label option on a Predefinition. When the Predefinition is applied to an item, it will be auto-labeled with a Name generated by the formula, in this case something like: C17-65.42#1.
