unknown
The value is not known. This value should not be used
in normal situations. All reasonable attempts should be made to determine
the appropriate value. Use of this value may result in rejection in
some situations.
NameTagLocation
Defines the locations where an equipment tag might be found.
WITSML
body
The body of the equipment. For tubular components this
specifies a location toward the middle of the component.
box
The female threaded end of a device.
pin
The male threaded end of a device.
other
This, by exclusion, tells a user to
look elsewhere than on the body or near the ends of a component.
unknown
The value is not known. This value should not be used
in normal situations. All reasonable attempts should be made to determine
the appropriate value. Use of this value may result in rejection in some situations.

serial number
Serial number contains a code which does not require any further
knowledge of an encoding scheme to manipulate or process.
The identifier is the only information in the "tag".
unknown
The value is not known. This value should not be used
in normal situations. All reasonable attempts should be made to determine
the appropriate value. Use of this value may result in rejection in some situations.
NameTagTechnology
Defines the mechanisms for attaching an equipment tag to an item.
WITSML
tagged
Independent identification components attached or embedded to a
larger component for purposes of identification of the larger component.
Tags typically use electronic, radio or sound based technologies and that
require a special non-optical device to read them. Radio Frequency
Identification (RFID tags) are of this type, as are some magnetic and sound
based identification technologies.
labeled
An optical label attached to a component. The label
may be glued, riveted or attached by some other method and may contain a
serial number, barcode or other optically recognized information. Note that
a label may possibly have a combination of identifiers associated with it,
such as a serial number, a barcode and an embedded RFID identifier. This
would generate three nameTags for the one physical label, two of
type 'label' for the barcode and serial number and one of type 'tagged' for
the RFID identifier.
intrinsic
Identification technologies where the intrinsic
properties of the component to be identified contain the identification
information and no other unique code has been added. For example, some
magnetic identification technologies use grooves machined into a component.
Some components may also be identified, for example, by their individual
sonic signature or optical profile.
stamped
An identification code physically stamped into the base
material of the component to be identified. Note that if a serial number is
stamped into a label attached to a component, 'labeled' should be used and
not 'stamped'. Stamped identifiers can wear off but can not fall off.
painted
Painted or stenciled on the material.
temporary
Temporary identification codes marked with grease pencil, chalk, or such.
unknown
The value is not known. This value should not be used
in normal situations. All reasonable attempts should be made to determine
the appropriate value. Use of this value may result in rejection in some situations.
