Attribute field names must be kept under 10 characters in
				  length to avoid truncating the field name during conversion operations. For
				  example, a shape file with the field name CARTOGRAPHIC will be truncated to
				  CARTOGRAPH if the shape file id converted to ArcInfo. File names should be kept
				  under 8 characters in length to conform to the "eight and three"
				  standard.

				Attribute Table Fields
These fields are required to be in a feature attribute table
				  directly associated with the corresponding digital parcel file. For example, if
				  the digital parcel file is a shapefile, then these items must be in the Dbase

				  and lot assigned to each parcel by the municipal assessor. This field is the
				  link to the municipal databases. It may not be possible to make this link
				  between the assessor's database and the digital parcel map for every parcel or
				  property record " a one to one relationship. This standard requires only an
				  initial effort to make the linkage as complete as possible. (character
				  field)
PARENT
The map_bk_lot listing in the assessor's database where
				  information about a parcel may be found. Some Maine towns organize their tax
				  assessing database so that only one bill is sent to each property owner. If the
				  property owner holds several lots only one listing in the assessor's database
				  will be made to serve for all of them. In these cases one map-block-lot
				  designation will be assigned to the combined listing. For the remaining lots,
				  the parent field contains a pointer to the appropriate map-block-plot listing.
