+## Definitions Used in this Document
+
+In this document we refer to `ReadableLogRecord` and `ReadWriteLogRecord` defined as follows.
+
+### ReadableLogRecord
+
+A function receiving this as an argument MUST be able to access all the
+information added to the [LogRecord](data-model.md#log-and-event-record-definition). It MUST also be able to
+access the [Instrumentation Scope](./data-model.md#field-instrumentationscope)
+and [Resource](./data-model.md#field-resource) information (implicitly)
+associated with the `LogRecord`.
+
+The [trace context fields](./data-model.md#trace-context-fields) MUST be populated from
+the resolved `Context` (either the explicitly passed `Context` or the
+current `Context`) when [emitted](./bridge-api.md#emit-a-logrecord).
+
+Counts for attributes due to collection limits MUST be available for exporters
+to report as described in
+the [transformation to non-OTLP formats](../common/mapping-to-non-otlp.md#dropped-attributes-count)
+specification.
+
+### ReadWriteLogRecord
+
+A function receiving this as an argument MUST be able to write to the
+full [LogRecord](data-model.md#log-and-event-record-definition) and additionally MUST be able to retrieve all
+information
+that was added to the `LogRecord` (as with
+[ReadableLogRecord](#readablelogrecord)).
