grouped together in the same box on site and will be separated out during dry-brushing. For any special finds recovered from the trench, coordinates and elevations will be taken.In order to determine the coordinates, a plumb bob will be held over the location of the special find, and then the distance from two of the baulk walls will be determined by extending a tape measure at a right angle from the string of the plumb bob to the string marking the boundaries of the trench. In order to determine the elevation of special finds, once again a plumb bob will be held over the find spot of the special find. Simultaneously, a string with a line level will be attached to a fixed datum point (26.14 cm) and will be pulled taught and level, so that it intersects with the string of the plumb bob. A tape measure will be held so that it runs parallel to the string of the plumb bob, and the elevation relative to the datum point may then be determined. As the elevation of the datum point on the master grid system is known

Open Context editors work with data contributors to annotate datasets to shared vocabularies, ontologies, and other standards using 'Linked Open Data' (LOD) methods.
The annotations presented above approximate some of the meaning in this contributed data record to concepts defined in shared standards. These annotations are provided to help make datasets easier to understand and use with other datasets.
