| Version / Format | Description | Strengths | Limitations |
|---|---|---|---|
| TomTom OpenLR Binary v3 | Original, low-bandwidth binary encoding | Compact, efficient, widely used in in-vehicle systems. | Tight coupling with TomTom decoder tools; hard harder to debug |
| TomTom OpenLR XML v3 | XML-based version from the original OpenLR white paper | Human-readable, well-documented | Verbose; best suited for internal or TomTom-centric use |
| TISA TPEG2-OLR (ISO 21219-22) | ISO-standardized adaptation (by TISA) in binary, protobuf, and TPEGml | Interoperable, ISO-compliant, used in TPEG services worldwide (broadcast and IP) | Not interoperable with TomTom or DATEX II XML; different field structure |
| DATEX II OpenLR XML | Adaptation for public traffic management systems | Integrates into existing DATEX II platforms | Incompatible at XML level with TomTom and TISA variants |
| TN-ITS OpenLR (XML & Binary) | Used in TN-ITS for static road data exchange (e.g. speed limits). In essence this is a reference to TomTom OpenLR whitepaper formats. | Used for communicating of infrastructure updates in TN-ITS environments |
