public static final AttributeKey<String> SERVICE_NAMESPACE
```
    A namespace for `service.name`.
    Note: A string value having a meaning that helps to distinguish a group of services, for example the team name that owns a group of services. `service.name` is expected to be unique within the same namespace. If `service.namespace` is not specified in the Resource then `service.name` is expected to be unique for all services that have no explicit namespace defined (so the empty/unspecified namespace is simply one more valid namespace). Zero-length namespace string is assumed equal to unspecified namespace.
  - SERVICE_INSTANCE_ID
```
public static final AttributeKey<String> SERVICE_INSTANCE_ID
```
    The string ID of the service instance.
    Note: MUST be unique for each instance of the same `service.namespace,service.name` pair (in other words `service.namespace,service.name,service.id` triplet MUST be globally unique). The ID helps to distinguish instances of the same service that exist at the same time (e.g. instances of a horizontally scaled service). It is preferable for the ID to be persistent and stay the same for the lifetime of the service instance, however it is acceptable that the ID is ephemeral and changes during important lifetime events for the service (e.g. service restarts). If the service has no inherent unique ID that can be used as the value of this attribute it is recommended to generate a random Version 1 or Version 4 RFC 4122 UUID (services aiming for reproducible UUIDs may also use Version 5, see RFC 4122 for more recommendations).

```
    If no [tech-specific attribute](#call-level-attributes-for-specific-technologies) is defined, this attribute is used to report the name of the database being accessed. For commands that switch the database, this should be set to the target database (even if the command fails).
    Note: In some SQL databases, the database name to be used is called "schema name".

    Note: While it would semantically make sense to set this, e.g., to a SQL keyword like `SELECT` or `INSERT`, it is not recommended to attempt any client-side parsing of `db.statement` just to get this property (the back end can do that if required).

  - EXCEPTION_TYPE
```
public static final AttributeKey<String> EXCEPTION_TYPE
```
    The type of the exception (its fully-qualified class name, if applicable). The dynamic type of the exception should be preferred over the static type in languages that support it.
  - EXCEPTION_MESSAGE
```
public static final AttributeKey<String> EXCEPTION_MESSAGE
```
    The exception message.
  - EXCEPTION_STACKTRACE
```
public static final AttributeKey<String> EXCEPTION_STACKTRACE
```
    A stacktrace as a string in the natural representation for the language runtime. The representation is to be determined and documented by each language SIG.
  - EXCEPTION_ESCAPED
```
public static final AttributeKey<Boolean> EXCEPTION_ESCAPED
```
    SHOULD be set to true if the exception event is recorded at a point where it is known that the exception is escaping the scope of the span.
    Note: An exception is considered to have escaped (or left) the scope of a span, if that span is ended while the exception is still logically "in flight". This may be actually "in flight" in some languages (e.g. if the exception is passed to a Context manager's `__exit__` method in Python) but will usually be caught at the point of recording the exception in most languages.
    It is usually not possible to determine at the point where an exception is thrown whether it will escape the scope of a span. However, it is trivial to know that an exception will escape, if one checks for an active exception just before ending the span, as done in the [example above](#exception-end-example).
    It follows that an exception may still escape the scope of the span even if the `exception.escaped` attribute was not set or set to false, since the event might have been recorded at a time where it was not clear whether the exception will escape.

```
    The primary server name of the matched virtual host. This should be obtained via configuration. If no such configuration can be obtained, this attribute MUST NOT be set ( `net.host.name` should be used instead).
    Note: `http.url` is usually not readily available on the server side but would have to be assembled in a cumbersome and sometimes lossy process from other information (see e.g. open-telemetry/opentelemetry-python/pull/148). It is thus preferred to supply the raw data that is available.

    Message keys in Kafka are used for grouping alike messages to ensure they're processed on the same partition. They differ from `messaging.message_id` in that they're not unique. If the key is `null`, the attribute MUST NOT be set.
    Note: If the key type is not string, it's string representation has to be supplied for the attribute. If the key has no unambiguous, canonical string form, don't include its value.
  - MESSAGING_KAFKA_CONSUMER_GROUP
