Reference Data Library Entities
This section contains tables which depict how various Windchill object-specific attributes are represented in a Reference Data Library (RDL). The following namespace conventions are used for representing PLCS and PTC reference data representation:
• PTC stands for urn:plcs:rdl:ptc
• PLCS stands for urn:plcs:std:rdl
Reference Data Entry
This section represents how certain common attributes present in various Windchill Objects such as WTPart or WTDocument are represented in an RDL.

Reference Data Entries for BusinessField Attributes
In PLCS, attribute name and unit values are usually referred with a specific Reference Data (RD) entry. Since users define attributes on production system, it is suggested that you create your own RD-specific entry. For unit values, base unit-specific RD entries are already incorporated in the data exchange standards.
The following table depicts the common base unit’s specific RDL entries already incorporated into standard PLCS Import export-specific operation.
Unit Name
RD Entry

M
PLCS: m_Length_unit

G
PLCS : g_Mass_unit
Context_dependent_unit and Mass_unit
S

PLCS:A_ Electric_current_unit

K
PLCS: K_Thermodynamic_temperature_unit
Context_dependent_unit and Thermodynamic_temperature_unit
Mol
PLCS: mol_Amount_of_substance_unit
Context_dependent_unit and : Amount_of_substance_unit
Cd
PLCS: cd_Luminous_intensity_unit
Context_dependent_unit and : Luminous_intensity_unit
R
PLCS: r_Plane_angle_unit
Context_dependent_unit and : Plane_angle_unit
Sr
PLCS: sr_Solid_angle_unit
Context_dependent_unit and : Solid_angle_unit
Base units other than above 9 standard units.
PLCS: Context_dependent_unit
Units with Multiplication or exponent or division
PLCS:Derived_unit
* 
Base units are simple units without having any multiplication, exponent or division symbols whereas derived units are units which are generated from base units. Business field names are configured against Assigned_property parent class. Only for time based business field parent should be Date or Date_and_time_assignment class.
