The Tag Data Standards (TDS) define how EPC values are encoded on tags as well as how they are encoded for use in external applications. Each version of the TDS supports a set of identity types and establishes rules of representation for each of that identity type’s supported encodings. Highlights of the TDS versions supported out-of-the-box within iMotion 5.1:
TDS Version 1.24 Highlights
-
Targeted for use on Class 1 Gen1 tags.
-
6 supported identity types: GID, GTIN, SSCC, GIAI, GRAI, GLN.
-
Supported tag encodings: 64-bit and 96-bit.
-
Filter values do not have a corresponding numeric value.
-
Some encoding schemes are incorrect.
TDS Version 1.27 Highlights
-
Targeted for use on Class 1 Gen1 tags.
-
7 supported identity types: GID, GTIN, SSCC, GIAI, GRAI, GLN, DOD.
- Supported tag encodings: 64-bit and 96 bit.
- Some filter values are different than those defined in 1.24 (Some changes introduced in version 1.26).
- Filter values are normative.
- Inconsistencies found in 1.24 included although some addressed in previous TDS versions.
Additional TDS versions will be supported in iMotion through downloadable encoding adapters as those TDS versions are ratified. iMotion developers and users benefit from the following capability within each iMotion encoding adapter:
-
Users can easily create EPC values for tag emulations within the Device Emulator through a wizard-based dialog.
-
Users can easily create filter and group patterns for ALE specifications through a wizard based dialog.
-
Developers can easily encode and decode EPC values as well as create and process filter and group patterns through a powerful object oriented API.
-
Users and developers can choose among any of the supported TDS versions.
