Data Sources for RFID Fields
Data
Source
Description
Field
When Field is selected, an existing field on the label can be chosen from a drop down list in the Data
column.For labels, the list of fields is limited to variable text and bar code fields.For tags, only variable
text can be used.
Choice
When Choice is selected, a drop down list in the Data column restricts values for this DOD field to a
predefined list.
New
Field
When New Field is selected, a field name can be entered in the Data column that does not yet exist
on the label but will be specified later.
URI Configuration
Note: There can be only one block with an EPC, DoD, or URI data source for a label. Once you have a block
configured using EPC, DoD, or URI encoding, other blocks that you wish to configure will be limited to the
other data sources (Unused, Fixed, New Field, or Field).
A Uniform Resource Identifier (URI) is a character string representation that is used to identity a
resource.A Uniform Reference Name (URN) is a URI that identifies a resource by name within a
namespace.Loftware uses the urn:epc namespace. The resource name includes the data type, the
encoding type, followed by the encoding fields:
urn:epc:type:EncName:EncodingFields
where type is the data type, EncName is the encoding type used, and EncodingFields are the data fields
required by the encoding type, separated by dot marks.
urn:epc:tag:gid-96:6289.11800.4058
In this example, the GID-96 encoding fields part of the URI are entered in the format
GeneralManagerNumber.ObjectClass.SerialNumber

The following example illustrates URI data representation.
