-// Binary annotations are tags applied to a Span to give it context. For
-// example, a binary annotation of "http.uri" could the path to a resource in a
-// RPC call.
-//
-// Binary annotations of type STRING are always queryable, though more a
-// historical implementation detail than a structural concern.
-//
-// Binary annotations can repeat, and vary on the host. Similar to Annotation,
-// the host indicates who logged the event. This allows you to tell the
-// difference between the client and server side of the same key. For example,
-// the key "http.uri" might be different on the client and server side due to
-// rewriting, like "/api/v1/myresource" vs "/myresource. Via the host field,
-// you can see the different points of view, which often help in debugging.
-//
-// Attributes:
-//  - Key
-//  - Value
-//  - AnnotationType
-//  - Host: The host that recorded tag, which allows you to differentiate between
-// multiple tags with the same key. There are two exceptions to this.
-//
-// When the key is CLIENT_ADDR or SERVER_ADDR, host indicates the source or
-// destination of an RPC. This exception allows zipkin to display network
-// context of uninstrumented services, or clients such as web browsers.

+// A trace is a series of spans (often RPC calls) which form a latency tree.
+// 
+// The root span is where trace_id = id and parent_id = Nil. The root span is
+// usually the longest interval in the trace, starting with a SERVER_RECV
+// annotation and ending with a SERVER_SEND.
+// 
+// Attributes:
+//  - TraceID
+//  - Name: Span name in lowercase, rpc method for example
+// 
+// Conventionally, when the span name isn't known, name = "unknown".
+//  - ID
+//  - ParentID
+//  - Annotations
+//  - BinaryAnnotations
+//  - Debug
+//  - Timestamp: Microseconds from epoch of the creation of this span.
+// 
+// This value should be set directly by instrumentation, using the most
+// precise value possible. For example, gettimeofday or syncing nanoTime
+// against a tick of currentTimeMillis.
+// 
+// For compatibility with instrumentation that precede this field, collectors
+// or span stores can derive this via Annotation.timestamp.
+// For example, SERVER_RECV.timestamp or CLIENT_SEND.timestamp.
+// 
+// This field is optional for compatibility with old data: first-party span
+// stores are expected to support this at time of introduction.
+//  - Duration: Measurement of duration in microseconds, used to support queries.
+// 
+// This value should be set directly, where possible. Doing so encourages
+// precise measurement decoupled from problems of clocks, such as skew or NTP
+// updates causing time to move backwards.
+// 
+// For compatibility with instrumentation that precede this field, collectors
+// or span stores can derive this by subtracting Annotation.timestamp.
+// For example, SERVER_SEND.timestamp - SERVER_RECV.timestamp.
+// 
+// If this field is persisted as unset, zipkin will continue to work, except
+// duration query support will be implementation-specific. Similarly, setting
+// this field non-atomically is implementation-specific.
+// 
+// This field is i64 vs i32 to support spans longer than 35 minutes.
+//  - TraceIDHigh: Optional unique 8-byte additional identifier for a trace. If non zero, this
+// means the trace uses 128 bit traceIds instead of 64 bit.
