| JSON | JavaScript Object Notation |
| MetaInfo | Meta-Information in the form of a key-value map, which is given from DM to external service processors. |
| ODX | Open Diagnostic Data Exchange (Standardized diagnostic data description format as of ISO-22901) |
| REST | Representational State Transfer |
| SDG | Special Data Group |
| SID | Service Identifier, identifying a diagnostic service according to UDS, such as 0x14 ClearDiagnosticInformation |
| SOVD | Service-Oriented Vehicle Diagnostics |
| TLS | Transport Layer Security |
| UDS | Unified Diagnostic Services |
| URI | Uniform Resource Identifier |
| URL | Uniform Resource Locator |
| DID | Data Identifier according to ISO 14229-1[3]. This 16 bit value uniquely defines one ore more data elements (parameters) that can are used in diagnostics to read, write or control data. |
| NRC | Negative Response Code used by UDS in the diagnostic re- sponse to indicate the tester that a certain failure has occurred and the diagnostic request was not processed. |
| Diagnostic Server instance | Diagnostic Server (DM) is intended to support an own Diagnostic Server instance per installed SoftwareCluster, see section 2.2 for a detailed description. Each of those Server instances has and manages its own resources and is responsible for dispatching and processing of diagnostic services. |
| Extended Data Records | Contains statistical data for a DTC. Extended data records are assigned to DTCs and maintained and stored by the DM. |
| Snapshot Record | Snapshots (sometimes referred to as freeze frames ) are spe- cific data records associated with a DTC and stored in the fault memory at a certain point of time during fault detection. The DTC specific data-parameters are intended to ease the fault isolation process. |
| SoftwareCluster | A SoftwareCluster groups all AUTOSAR artifacts which are rele- vant to deploy software on a machine. This includes the defini- tion of applications, i.e. their executables, application manifests, communication and diagnostics. In the context of diagnostics a SoftwareCluster can be addressed individually by its own set of diagnostic addresses. |
| SOVD entity | Entity in context of SOVD[1] |
| SOVD lock | SOVD locking mechanism as defined by [1] |
| UDS service | A diagnostic service as defined in ISO 14229-1[3]. |
| Non-volatile Memory | In the context of DM, Non-volatile Memory refers to the persistent information over the shutdown of the DM process. This does not depend on HW details. |
