| = GraphSON |
| |
| image:../../../static/images/gremlin-graphson.png[width=350,float=left] GraphSON is a JSON-based format that is designed for human readable |
| output that is easily supported in any programming language through the wide-array of JSON parsing libraries that |
| exist on virtually all platforms. GraphSON versions 1 to 3 were considered to be both a "graph" format and a |
| generalized object serialization format. That characteristic makes it useful as a serialization format for Gremlin |
| Server where arbitrary objects of varying types may be returned as results. However, starting in GraphSON 4, GraphSON |
| is only intended to be a network serialization format that is only able to serialize specific types defined by the |
| format. It is only meant to be used with the TinkerPop HTTP API. |
| |
| When considering GraphSON as a "graph" format, the relevant feature to consider is the `writeGraph` and `readGraph` |
| methods on the `GraphSONWriter` and `GraphSONReader` interfaces, respectively. These methods write the entire `Graph` |
| instance as output or read an entire `Graph` instance input and they do so in a way external to generalized object |
| serialization. In other words, the output of: |
| |
| [source,java] |
| ---- |
| final Graph graph = TinkerFactory.createModern(); |
| final GraphWriter writer = graph.io(IoCore.graphson()).writer(); |
| writer.writeGraph("tinkerpop-modern.json"); |
| ---- |
| |
| will be different of: |
| |
| [source,java] |
| ---- |
| final Graph graph = TinkerFactory.createModern(); |
| final GraphWriter writer = graph.io(IoCore.graphson()).writer(); |
| final OutputStream os = new FileOutputStream("tinkerpop-modern.json"); |
| writer.writeObject(os, graph); |
| ---- |
| |
| Generalized object serialization will be discussed later in this section, so for now the focus will be on the "graph" |
| format. Unlike GraphML, GraphSON does not use an edge list format. It uses an adjacency list. In the adjacency list, |
| each vertex is essentially a line in the file and the vertex line contains a list of all the edges associated with |
| that vertex. The GraphSON 4.0 representation looks like this for the Modern toy graph: |

| At a glance, one can see that this is not a valid JSON document (although it is a valid https://jsonlines.org[JSON Lines] document). While that form may seem incorrect, there is a reason. |
| The "graph" format is designed by default to be splittable, such that distributed systems like Spark can easily divide |
| the GraphSON file for processing. If this data were represented as an "array of vertices" with square brackets at the |
| beginning and end of the file, the format would be less conducive to fit that purpose. It is possible to change this |
| behavior by building the `GraphSONWriter` with the `wrapAdjacencyList` setting set to `true`, in which case the output |
| will be a valid JSON document that looks like this: |
| |
| [source,json] |

| NOTE: The `writeGraph` method essentially calls `writeVertices` with the directionality of `BOTH`. The `writeVertices` |
| method simply calls `writeVertex` which detaches each `Vertex` instance into a directional `StarGraph` which forms |
| the basis for the format. |
| |
| The following sections discuss the GraphSON object serialization format as available in each version of GraphSON. Core |
| to understanding these sections is to understand that GraphSON can be produced with and without types being embedded |
| in the output. Without embedded types, the type system is restricted to standard JSON types of `Object`, `List`, |
| `String`, `Number`, `Boolean` and that will lead to "lossyness" in the format (i.e. a float will be interpreted as |
| double). It is also worth considering that choosing a GraphSON format without embedded types may also restrict the |
| type of results that can be obtained. For example, `g.V().groupCount()` returns a format with a `Map`. That's fine |
| for GraphSON, but the key in that `Map` is a complex object (i.e. a `Vertex`) and as such is not compatible with JSON |
| itself which can only support `String` keys. |
| |
| WARNING: The `application/json` mime type is shared with all versions of GraphSON and their variations and does not |
| reflect a particular one. Servers will return the GraphSON version and variation that this mime type is configured for |
| and it could be different (or change) from server to server. When building applications, it is recommended that the |
| mime type is made explicit on requests to avoid breaking changes or unexpected results. |

| [[graphson-4]] |
| == Version 4.0 |
| |
| Version 4.0 of GraphSON was first introduced on TinkerPop 4.0.0 and is represented by the |
| `application/vnd.gremlin-v4.0+json` mime type. There also exists an untyped version: |
| `application/vnd.gremlin-v4.0+json;types=false`. It is very similar to GraphSON 3.0, with just several key differences: |
| many underused or duplicated types have been removed, labels are now list of strings and request/response formats have |
| changed quite a bit, and custom types have been replaced with Provider Defined Type (PDT). |
