format</a> was derived from and improved upon <a href=https://ubjson.org>Universal Binary JSON(UBJSON)</a> specification (Draft 12). Specifically, it introduces an optimized array container for efficient storage of N-dimensional packed arrays (<strong>ND-arrays</strong>); it also adds 4 new type markers - <code>[u] - uint16</code>, <code>[m] - uint32</code>, <code>[M] - uint64</code> and <code>[h] - float16</code> - to unambiguously map common binary numeric types; furthermore, it uses little-endian (LE) to store all numerics instead of big-endian (BE) as in UBJSON to avoid unnecessary conversions on commonly available platforms.</p> <p>Compared to other binary JSON-like formats such as MessagePack and CBOR, both BJData and UBJSON demonstrate a rare combination of being both binary and <strong>quasi-human-readable</strong>. This is because all semantic elements in BJData and UBJSON, including the data-type markers and name/string types are directly human-readable. Data stored in the BJData/UBJSON format are not only compact in size, fast to read/write, but also can be directly searched or read using simple processing.</p> <div class="admonition abstract"> <p class=admonition-title>References</p> <ul> <li><a href=https://neurojson.org/bjdata/draft2>BJData Specification</a></li> </ul> </div> <h2 id=serialization>Serialization<a class=headerlink href=#serialization title="Permanent link">¶</a></h2> <p>The library uses the following mapping from JSON values types to BJData types according to the BJData specification:</p> <table> <thead> <tr> <th>JSON value type</th> <th>value/range</th> <th>BJData type</th> <th>marker</th> </tr> </thead> <tbody> <tr> <td>null</td> <td><code>null</code></td> <td>null</td> <td><code>Z</code></td> </tr> <tr> <td>boolean</td> <td><code>true</code></td> <td>true</td> <td><code>T</code></td> </tr> <tr> <td>boolean</td> <td><code>false</code></td> <td>false</td> <td><code>F</code></td> </tr> <tr> <td>number_integer</td> <td>-9223372036854775808..-2147483649</td> <td>int64</td> <td><code>L</code></td> </tr> <tr> <td>number_integer</td> <td>-2147483648..-32769</td> <td>int32</td> <td><code>l</code></td> </tr> <tr> <td>number_integer</td> <td>-32768..-129</td> <td>int16</td> <td><code>I</code></td> </tr> <tr> <td>number_integer</td> <td>-128..127</td> <td>int8</td> <td><code>i</code></td> </tr> <tr> <td>number_integer</td> <td>128..255</td> <td>uint8</td> <td><code>U</code></td> </tr> <tr> <td>number_integer</td> <td>256..32767</td> <td>int16</td> <td><code>I</code></td> </tr> <tr> <td>number_integer</td> <td>32768..65535</td> <td>uint16</td> <td><code>u</code></td> </tr> <tr> <td>number_integer</td> <td>65536..2147483647</td> <td>int32</td> <td><code>l</code></td> </tr> <tr> <td>number_integer</td> <td>2147483648..4294967295</td> <td>uint32</td> <td><code>m</code></td> </tr> <tr> <td>number_integer</td> <td>4294967296..9223372036854775807</td> <td>int64</td> <td><code>L</code></td> </tr> <tr> <td>number_integer</td> <td>9223372036854775808..18446744073709551615</td> <td>uint64</td> <td><code>M</code></td> </tr> <tr> <td>number_unsigned</td> <td>0..127</td> <td>int8</td> <td><code>i</code></td> </tr> <tr> <td>number_unsigned</td> <td>128..255</td> <td>uint8</td> <td><code>U</code></td> </tr> <tr> <td>number_unsigned</td> <td>256..32767</td> <td>int16</td> <td><code>I</code></td> </tr> <tr> <td>number_unsigned</td> <td>32768..65535</td> <td>uint16</td> <td><code>u</code></td> </tr> <tr> <td>number_unsigned</td> <td>65536..2147483647</td> <td>int32</td> <td><code>l</code></td> </tr> <tr> <td>number_unsigned</td> <td>2147483648..4294967295</td> <td>uint32</td> <td><code>m</code></td> </tr> <tr> <td>number_unsigned</td> <td>4294967296..9223372036854775807</td> <td>int64</td> <td><code>L</code></td> </tr> <tr> <td>number_unsigned</td> <td>9223372036854775808..18446744073709551615</td> <td>uint64</td> <td><code>M</code></td> </tr> <tr> <td>number_float</td> <td><em>any value</em></td> <td>float64</td> <td><code>D</code></td> </tr> <tr> <td>string</td> <td><em>with shortest length indicator</em></td> <td>string</td> <td><code>S</code></td> </tr> <tr> <td>array</td> <td><em>see notes on optimized format/ND-array</em></td> <td>array</td> <td><code>[</code></td> </tr> <tr> <td>object</td> <td><em>see notes on optimized format</em></td> <td>map</td> <td><code>{</code></td> </tr> </tbody> </table> <div class="admonition success"> <p class=admonition-title>Complete mapping</p> <p>The mapping is <strong>complete</strong> in the sense that any JSON value type can be converted to a BJData value.</p> <p>Any BJData output created by <code>to_bjdata</code> can be successfully parsed by <code>from_bjdata</code>.</p> </div> <div class="admonition warning"> <p class=admonition-title>Size constraints</p> <p>The following values can <strong>not</strong> be converted to a BJData value:</p> <ul> <li>strings with more than 18446744073709551615 bytes, i.e., <span class=arithmatex><span class=MathJax_Preview>2^{64}-1</span><script type=math/tex>2^{64}-1</script></span> bytes (theoretical)</li> </ul> </div> <div class="admonition info"> <p class=admonition-title>Unused BJData markers</p> <p>The following markers are not used in the conversion:</p> <ul> <li><code>Z</code>: no-op values are not created.</li> <li><code>C</code>: single-byte strings are serialized with <code>S</code> markers.</li> </ul> </div> <div class="admonition info"> <p class=admonition-title>NaN/infinity handling</p> <p>If NaN or Infinity are stored inside a JSON number, they are serialized properly.

In BJData, all numerical data types (integers <code>UiuImlML</code> and floating-point values <code>hdD</code>) are stored in the little-endian (LE) byte order as opposed to big-endian as used by UBJSON. Adopting LE to store numeric records avoids unnecessary byte swapping on most modern computers where LE is used as the default byte order.</p> </div> <div class="admonition info"> <p class=admonition-title>Optimized formats</p> <p>Optimized formats for containers are supported via two parameters of <a href=../../../api/basic_json/to_bjdata/ ><code>to_bjdata</code></a>:</p> <ul> <li>Parameter <code>use_size</code> adds size information to the beginning of a container and removes the closing marker.</li> <li>Parameter <code>use_type</code> further checks whether all elements of a container have the same type and adds the type marker to the beginning of the container. The <code>use_type</code> parameter must only be used together with <code>use_size = true</code>.</li> </ul> <p>Note that <code>use_size = true</code> alone may result in larger representations - the benefit of this parameter is that the receiving side is immediately informed of the number of elements in the container.</p> </div> <div class="admonition info"> <p class=admonition-title>ND-array optimized format</p> <p>BJData extends UBJSON's optimized array <strong>size</strong> marker to support ND-arrays of uniform numerical data types (referred to as <em>packed arrays</em>). For example, the 2-D <code>uint8</code> integer array <code>[[1,2],[3,4],[5,6]]</code>, stored as nested optimized array in UBJSON <code>[ [$U#i2 1 2 [$U#i2 3 4 [$U#i2 5 6 ]</code>, can be further compressed in BJData to <code>[$U#[$i#i2 2 3 1 2 3 4 5 6</code> or <code>[$U#[i2 i3] 1 2 3 4 5 6</code>.</p> <p>To maintain type and size information, ND-arrays are converted to JSON objects following the <strong>annotated array format</strong> (defined in the <a href=https://github.com/NeuroJSON/jdata/blob/master/JData_specification.md#annotated-storage-of-n-d-arrays)>JData specification (Draft 3)</a>), when parsed using <a href=../../../api/basic_json/from_bjdata/ ><code>from_bjdata</code></a>. For example, the above 2-D <code>uint8</code> array can be parsed and accessed as</p> <div class=highlight><pre><span></span><code><span class=p>{</span> |

| </code></pre></div> <p>Likewise, when a JSON object in the above form is serialzed using <a href=../../../api/basic_json/to_bjdata/ ><code>to_bjdata</code></a>, it is automatically converted into a compact BJData ND-array. The only exception is, that when the 1-dimensional vector stored in <code>"_ArraySize_"</code> contains a single integer or two integers with one being 1, a regular 1-D optimized array is generated.</p> <p>The current version of this library does not yet support automatic detection of and conversion from a nested JSON array input to a BJData ND-array.</p> </div> <div class="admonition info"> <p class=admonition-title>Restrictions in optimized data types for arrays and objects</p> <p>Due to diminished space saving, hampered readability, and increased security risks, in BJData, the allowed data types following the <code>$</code> marker in an optimized array and object container are restricted to <strong>non-zero-fixed-length</strong> data types. Therefore, the valid optimized type markers can only be one of <code>UiuImlMLhdDC</code>. This also means other variable (<code>[{SH</code>) or zero-length types (<code>TFN</code>) can not be used in an optimized array or object in BJData.</p> </div> <div class="admonition info"> <p class=admonition-title>Binary values</p> <p>If the JSON data contains the binary type, the value stored is a list of integers, as suggested by the BJData documentation. In particular, this means that the serialization and the deserialization of JSON containing binary values into BJData and back will result in a different JSON object.</p> </div> <details class=example> <summary>Example</summary> <div class=highlight><pre><span></span><code><span class=cp>#include</span><span class=w> </span><span class=cpf><iostream></span> |
