+JSON Schema Test Suite [![Build Status](https://travis-ci.org/json-schema/JSON-Schema-Test-Suite.png?branch=develop)](https://travis-ci.org/json-schema/JSON-Schema-Test-Suite)
+======================
+
+This repository contains a set of JSON objects that implementors of JSON Schema
+validation libraries can use to test their validators.
+
+It is meant to be language agnostic and should require only a JSON parser.
+
+The conversion of the JSON objects into tests within your test framework of
+choice is still the job of the validator implementor.
+
+Structure of a Test
+-------------------
+
+If you're going to use this suite, you need to know how tests are laid out. The
+tests are contained in the `tests` directory at the root of this repository.
+
+Inside that directory is a subdirectory for each draft or version of the
+schema. We'll use `draft3` as an example.
+
+If you look inside the draft directory, there are a number of `.json` files,
+which logically group a set of test cases together. Often the grouping is by
+property under test, but not always, especially within optional test files
+(discussed below).
+
+Inside each `.json` file is a single array containing objects. It's easiest to
+illustrate the structure of these with an example:
+
+```json
+    {
+        "description": "the description of the test case",
+        "schema": {"the schema that should" : "be validated against"},
+        "tests": [
+            {
+                "description": "a specific test of a valid instance",
+                "data": "the instance",
+                "valid": true
+            },
+            {
+                "description": "another specific test this time, invalid",
+                "data": 15,
+                "valid": false
+            }
+        ]
+    }
+```
+
+So a description, a schema, and some tests, where tests is an array containing
+one or more objects with descriptions, data, and a boolean indicating whether
+they should be valid or invalid.
+
+Coverage
+--------
+
+Draft 3 and 4 should have full coverage. If you see anything missing or think
+there is a useful test missing, please send a pull request or open an issue.

+# Schema
+
+## Status: experimental, shall be included in v1.1
+
+JSON Schema is a draft standard for describing format of JSON. The schema itself is also a JSON. By validating a JSON with JSON Schema, your code can safely access the JSON without manually checking types, or whether a key exists, etc.
+
+RapidJSON implemented a JSON Schema validator for [JSON Schema Draft v4](http://json-schema.org/documentation.html). If you do not familiar with JSON Schema, you may refer to [Understanding JSON Schema](http://spacetelescope.github.io/understanding-json-schema/).
+
+## Basic Usage
+
+First of all, you need to parse a JSON Schema into `Document`, and then compile the `Document` into `SchemaDocument`.
+
+Secondly, construct a `SchemaValidator` with the `SchedmaDocument`. It is similar to a `Writer` in the sense of handling SAX events. So, you can use `document.Accept(validator)` to validate a document, and then check the validity.
+
+~~~cpp
+#include "rapidjson/schema.h"
+
+// ...
+
+Document sd;
+if (!sd.Parse(schemaJson)) {
+    // the schema is not a valid JSON.
+    // ...       
+}
+SchemaDocument schema(sd); // Compile a Document to SchemaDocument
+// sd is no longer needed here.
+
+Document d;
+if (!d.Parse(inputJson)) {
+    // the input is not a valid JSON.
+    // ...       
+}
+
+SchemaValidator validator(schema);
+if (!d.Accept(validator)) {
+    // Input JSON is invalid according to the schema
+    // Output diagnostic information
+    StringBuffer sb;
+    validator.GetInvalidSchemaPointer().StringifyUriFragment(sb);
+    printf("Invalid schema: %s\n", sb.GetString());
+    printf("Invalid keyword: %s\n", validator.GetInvalidSchemaKeyword());
+    sb.Clear();
+    validator.GetInvalidDocumentPointer().StringifyUriFragment(sb);
+    printf("Invalid document: %s\n", sb.GetString());
+}
+~~~
+
+Some notes:
+
+* One `SchemaDocment` can be referenced by multiple `SchemaValidator`s. It will not be modified by `SchemaValidator`s.
+* A `SchemaValidator` may be reused to validate multiple documents. To run it for other documents, call `validator.Reset()` first.
+
+## Validation during parsing/serialization
+
+Differ to most JSON Schema validator implementations, RapidJSON provides a SAX-based schema validator. Therefore, you can parse a JSON from a stream while validating it on the fly. If the validator encounters a JSON value that invalidates the supplied schema, the parsing will be terminated immediately. This design is especially useful for parsing large JSON files.
+
+### DOM parsing
+
+For using DOM in parsing, `Document` needs some preparation and finailizaing tasks, in addition to recieving SAX events, thus it needs some work to route the reader, validator and the document. `SchemaValidatingReader` is a helper class that doing such work.
+
+~~~cpp
+#include "rapidjson/filereadstream.h"
+
+// ...
+SchemaDocument schema(sd); // Compile a Document to SchemaDocument
+
+// Use reader to parse the JSON
+FILE* fp = fopen("big.json", "r");
+FileReadStream is(fp, buffer, sizeof(buffer));
+
+// Parse JSON from reader, validate the SAX events, and store in d.
+Document d;
+SchemaValidatingReader<kParseDefaultFlags, FileReadStream, UTF8<> > reader(is, schema);
+d.Populate(reader);
+
+if (!reader.GetParseResult()) {
+    // Not a valid JSON
+    // When reader.GetParseResult().Code() == kParseErrorTermination,
+    // it may be terminated by:
+    // (1) the validator found that the JSON is invalid according to schema; or
+    // (2) the input stream has I/O error.
+
+    // Check the validation result
+    if (!reader.IsValid()) {
+        // Input JSON is invalid according to the schema
+        // Output diagnostic information
+        StringBuffer sb;
+        reader.GetInvalidSchemaPointer().StringifyUriFragment(sb);
+        printf("Invalid schema: %s\n", sb.GetString());
+        printf("Invalid keyword: %s\n", reader.GetInvalidSchemaKeyword());
+        sb.Clear();
+        reader.GetInvalidDocumentPointer().StringifyUriFragment(sb);
+        printf("Invalid document: %s\n", sb.GetString());
+    }
+}
+~~~
+
+### SAX parsing
+
+For using SAX in parsing, it is much simpler. If it only need to validate the JSON without further processing, it is simply:
+
+~~~
+SchemaValidator validator(schema);
+Reader reader;
+if (!reader.Parse(stream, validator)) {
+    if (!validator.IsValid()) {
+        // ...    
+    }
+}
+~~~
+
+This is exactly the method used in [schemavalidator](example/schemavalidator/schemavalidator.cpp) example. The distinct advantage is low memory usage, no matter how big the JSON was (the memory usage depends on the complexity of the schema).
+
+If you need to handle the SAX events further, then you need to use the template class `GenericSchemaValidator` to set the output handler of the validator:
+
+~~~
+MyHandler handler;
+GenericSchemaValidator<SchemaDocument, MyHandler> validator(schema, handler);
+Reader reader;
+if (!reader.Parse(ss, validator)) {
+    if (!validator.IsValid()) {
+        // ...    
+    }
+}
+~~~
+
+### Serialization
+
+It is also possible to do validation during serializing. This can ensure the result JSON is valid according to the JSON schema.
+
+~~~
+StringBuffer sb;
+Writer<StringBuffer> writer(sb);
+GenericSchemaValidator<SchemaDocument, Writer<StringBuffer> > validator(s, writer);
+if (!d.Accept(validator)) {
+    // Some problem during Accept(), it may be validation or encoding issues.
+    if (!validator.IsValid()) {
+        // ...
+    }
+}
+~~~
+
+Of course, if your appication only needs SAX-style serialization, it can simply send SAX events to `SchemaValidator` instead of `Writer`.
+
+## Remote Schema
+
+JSON Schema supports [`$ref` keyword](http://spacetelescope.github.io/understanding-json-schema/structuring.html), which is a [JSON pointer](pointer.md) referencing to a local or remote schema. Local pointer is prefixed with `#`, while remote pointer is an relative or absolute URI. For example:
+
+~~~js
+{ "$ref": "definitions.json#/address" }
+~~~
+
+As `SchemaValidator` does not know how to resolve such URI, it needs a user-provided `IRemoteSchemaDocumentProvider` instance to do so.
+
+~~~
+class MyRemoteSchemaDocumentProvider : public IRemoteSchemaDocumentProvider {
+public:
+    virtual const SchemaDocument* GetRemoteDocument(const char* uri, SizeTyp length) {
+        // Resolve the uri and returns a pointer to that schema.
+    }
+};
+
+// ...
+
+MyRemoteSchemaDocumentProvider provider;
+SchemaValidator validator(schema, &provider);
+~~~
+
+## Conformance
+
+RapidJSON passed 262 out of 263 tests in [JSON Schema Test Suite](https://github.com/json-schema/JSON-Schema-Test-Suite) (Json Schema draft 4).
+
+The failed test is "changed scope ref invalid" of "change resolution scope" in `refRemote.json`. It is due to that `id` schema keyword and URI combining function are not implemented.
+
+Besides, the `format` schema keyword for string values is ignored, since it is not required by the specification.
+
+### Regular Expression
+
+The schema keyword `pattern` and `patternProperties` uses regular expression to match the required pattern.
+
+RapidJSON implemented a simple DFA regular expression engine, which is used by default. It supports the following syntax.
+
+|Syntax|Description|
+|------|-----------|
+|`ab`    | Concatenation
+|`a|b`   | Alternation
+|`a?`    | Zero or one
+|`a*`    | Zero or more
+|`a+`    | One or more
+|`a{3}`  | Exactly 3 times
+|`a{3,}` | At least 3 times
+|`a{3,5}`| 3 to 5 times
+|`(ab)`  | Grouping
+|`^a`    | At the beginning
+|`a$`    | At the end
+|`.`     | Any character
+|`[abc]` | Character classes
+|`[a-c]` | Character class range
+|`[a-z0-9_]` | Character class combination
+|`[^abc]` | Negated character classes
+|`[^a-c]` | Negated character class range
+|`[\b]`   | Backspace (U+0008)
+|``\|`, `\\`, ...  | Escape characters
+|`\f` | Form feed (U+000C)
+|`\n` | Line feed (U+000A)
+|`\r` | Carriage return (U+000D)
+|`\t` | Tab (U+0009)
+|`\v` | Vertical tab (U+000B)
+
+For C++11 compiler, it is also possible to use the `std::regex` by defining `RAPIDJSON_SCHEMA_USE_INTERNALREGEX=0` and `RAPIDJSON_SCHEMA_USE_STDREGEX=1`. If your schemas do not need `pattern` and `patternProperties`, you can set both macros to zero to disable this feature, which will reduce some code size.
+
+## Performance
+
+Most C++ JSON libraries have not yet supporting JSON Schema. So we tried to evluate the performance of RapidJSON's JSON Schema validator according to [json-schema-benchmark](https://github.com/ebdrup/json-schema-benchmark), which tests 11 JavaScript libraries running on Node.js.
+
+That benchmark runs validations on [JSON Schema Test Suite](https://github.com/json-schema/JSON-Schema-Test-Suite), in which some test suites and tests are excluded.
+
+On a Mac Book Pro (2.8 GHz Intel Core i7), the following results are gathered.
+
+|Validator|Relative speed|Number of test runs per second|
+|---------|:------------:|:----------------------------:|
+|RapidJSON|36521%|7220217|

+# Schema
+
+## 状态: 实验性，应该会合进 v1.1
+
+JSON Schema 是描述 JSON 格式的一个标准草案。一个 schema 本身也是一个 JSON。使用 JSON Schema 去校验 JSON，可以让你的代码安全地访问 DOM，而无须检查类型或键值是否存在等。这也能确保输出的 JSON 是符合指定的 schema。
+
+RapidJSON 实现了一个 [JSON Schema Draft v4](http://json-schema.org/documentation.html) 的校验器。若你不熟悉 JSON Schema，可以参考 [Understanding JSON Schema](http://spacetelescope.github.io/understanding-json-schema/)。
+
+[TOC]
+
+## 基本用法
+
+首先，你要把 JSON Schema 解析成 `Document`，再把它编译成一个 `SchemaDocument`。
+
+然后，利用该 `SchemaDocument` 创建一个 `SchemaValidator`。它与 `Writer` 相似，都是能够处理 SAX 事件的。因此，你可以用 `document.Accept(validator)` 去校验一个 JSON，然后再获取校验结果。
+
+~~~cpp
+#include "rapidjson/schema.h"
+
+// ...
+
+Document sd;
+if (!sd.Parse(schemaJson)) {
+    // the schema is not a valid JSON.
+    // ...       
+}
+SchemaDocument schema(sd); // Compile a Document to SchemaDocument
+// sd is no longer needed here.
+
+Document d;
+if (!d.Parse(inputJson)) {
+    // the input is not a valid JSON.
+    // ...       
+}
+
+SchemaValidator validator(schema);
+if (!d.Accept(validator)) {
+    // Input JSON is invalid according to the schema
+    // Output diagnostic information
+    StringBuffer sb;
+    validator.GetInvalidSchemaPointer().StringifyUriFragment(sb);
+    printf("Invalid schema: %s\n", sb.GetString());
+    printf("Invalid keyword: %s\n", validator.GetInvalidSchemaKeyword());
+    sb.Clear();
+    validator.GetInvalidDocumentPointer().StringifyUriFragment(sb);
+    printf("Invalid document: %s\n", sb.GetString());
+}
+~~~
+
+一些注意点：
+
+* 一个 `SchemaDocment` 能被多个 `SchemaValidator` 吊用。它不会被 `SchemaValidator` 修改。
+* 一个 `SchemaValidator` 可以重复使用来校验多个文件。在校验其他文件前，先调用 `validator.Reset()`。
+
+## 在解析／生成时进行校验
+
+与大部分 JSON Schema 校验器有所不同，RapidJSON 提供了一个基于 SAX 的 schema 校验器实现。因此，你可以在输入流解析 JSON 的同时进行校验。若校验器遇到一个与 schema 不符的值，就会立即终止解析。这设计对于解析大型 JSON 文件时特别有用。
+
+### DOM 解析
+
+在使用 DOM 进行解析时，`Document` 除了接收 SAX 事件外，还需做一些准备及结束工作，因此，为了连接 `Reader`、`SchemaValidator` 和 `Document` 要做多一点事情。`SchemaValidatingReader` 是一个辅助类去做那些工作。
+
+~~~cpp
+#include "rapidjson/filereadstream.h"
+
+// ...
+SchemaDocument schema(sd); // Compile a Document to SchemaDocument
+
+// Use reader to parse the JSON
+FILE* fp = fopen("big.json", "r");
+FileReadStream is(fp, buffer, sizeof(buffer));
+
+// Parse JSON from reader, validate the SAX events, and store in d.
+Document d;
+SchemaValidatingReader<kParseDefaultFlags, FileReadStream, UTF8<> > reader(is, schema);
+d.Populate(reader);
+
+if (!reader.GetParseResult()) {
+    // Not a valid JSON
+    // When reader.GetParseResult().Code() == kParseErrorTermination,
+    // it may be terminated by:
+    // (1) the validator found that the JSON is invalid according to schema; or
+    // (2) the input stream has I/O error.
+
+    // Check the validation result
+    if (!reader.IsValid()) {
+        // Input JSON is invalid according to the schema
+        // Output diagnostic information
+        StringBuffer sb;
+        reader.GetInvalidSchemaPointer().StringifyUriFragment(sb);
+        printf("Invalid schema: %s\n", sb.GetString());
+        printf("Invalid keyword: %s\n", reader.GetInvalidSchemaKeyword());
+        sb.Clear();
+        reader.GetInvalidDocumentPointer().StringifyUriFragment(sb);
+        printf("Invalid document: %s\n", sb.GetString());
+    }
+}
+~~~
+
+### SAX 解析
+
+使用 SAX 解析时，情况就简单得多。若只需要校验 JSON 而无需进一步处理，那么仅需要：
+
+~~~
+SchemaValidator validator(schema);
+Reader reader;
+if (!reader.Parse(stream, validator)) {
+    if (!validator.IsValid()) {
+        // ...    
+    }
+}
+~~~
+
+这种方式和 [schemavalidator](example/schemavalidator/schemavalidator.cpp) 例子完全相同。这带来的独特优势是，无论 JSON 多巨大，永远维持低内存用量（内存用量只与 Schema 的复杂度相关）。
+
+若你需要进一步处理 SAX 事件，便可使用模板类 `GenericSchemaValidator` 去设置校验器的输出 `Handler`：
+
+~~~
+MyHandler handler;
+GenericSchemaValidator<SchemaDocument, MyHandler> validator(schema, handler);
+Reader reader;
+if (!reader.Parse(ss, validator)) {
+    if (!validator.IsValid()) {
+        // ...    
+    }
+}
+~~~
+
+### 生成
+
+我们也可以在生成（serialization）的时候进行校验。这能确保输出的 JSON 符合一个 JSON Schema。
+
+~~~
+StringBuffer sb;
+Writer<StringBuffer> writer(sb);
+GenericSchemaValidator<SchemaDocument, Writer<StringBuffer> > validator(s, writer);
+if (!d.Accept(validator)) {
+    // Some problem during Accept(), it may be validation or encoding issues.
+    if (!validator.IsValid()) {
+        // ...
+    }
+}
+~~~
+
+当然，如果你的应用仅需要 SAX 风格的生成，那么只需要把 SAX 事件由原来发送到 `Writer`，改为发送到 `SchemaValidator`。
+
+## 远程 Schema
+
+JSON Schema 支持 [`$ref` 关键字](http://spacetelescope.github.io/understanding-json-schema/structuring.html)，它是一个[JSON pointer](pointer.md) 引用至一个本地（local）或远程（remote） schema。本地指针的首字符是 `#`，而远程指针是一个相对或绝对 URI。例如：
+
+~~~js
+{ "$ref": "definitions.json#/address" }
+~~~
+
+由于 `SchemaValidator` 并不知道如何处理那些 URI，它需要使用者提供一个 `IRemoteSchemaDocumentProvider` 的实例去处理。
+
+~~~
+class MyRemoteSchemaDocumentProvider : public IRemoteSchemaDocumentProvider {
+public:
+    virtual const SchemaDocument* GetRemoteDocument(const char* uri, SizeTyp length) {
+        // Resolve the uri and returns a pointer to that schema.
+    }
+};
+
+// ...
+
+MyRemoteSchemaDocumentProvider provider;
+SchemaValidator validator(schema, &provider);
+~~~
+
+## 标准的符合程度
+
+RapidJSON 通过了 [JSON Schema Test Suite](https://github.com/json-schema/JSON-Schema-Test-Suite) (Json Schema draft 4) 中 263 个测试的 262 个。
+
+没通过的测试是 `refRemote.json` 中的 "change resolution scope" - "changed scope ref invalid"。这是由于未实现 `id` schema 关键字及 URI 合并功能。
+
+除此以外，关于字符串类型的 `format` schema 关键字也会被忽略，因为标准中并没需求必须实现。
+
+### 正则表达式
+
+`pattern` 及 `patternProperties` 这两个 schema 关键字使用了正则表达式去匹配所需的模式。
+
+RapidJSON 实现了一个简单的 DFA 正则表达式引擎，并预设使用。它支持以下语法。
+
+|语法|描述|
+|------|-----------|
+|`ab`    | 串联
+|`a|b`   | 交替
+|`a?`    | 零或一次
+|`a*`    | 零或多次
+|`a+`    | 一或多次
+|`a{3}`  | 刚好 3 次
+|`a{3,}` | 至少 3 次
+|`a{3,5}`| 3 至 5 次
+|`(ab)`  | 分组
+|`^a`    | 在开始处
+|`a$`    | 在结束处
+|`.`     | 任何字符
+|`[abc]` | 字符组
+|`[a-c]` | 字符组范围
+|`[a-z0-9_]` | 字符组组合
+|`[^abc]` | 字符组取反
+|`[^a-c]` | 字符组范围取反
+|`[\b]`   | 退格符 (U+0008)
+|`\|`, `\\`, ...  | 转义字符
+|`\f` | 馈页 (U+000C)
+|`\n` | 馈行 (U+000A)
+|`\r` | 回车 (U+000D)
+|`\t` | 制表 (U+0009)
+|`\v` | 垂直制表 (U+000B)
+
+对于使用 C++11 编译器的使用者，也可使用 `std::regex`，只需定义 `RAPIDJSON_SCHEMA_USE_INTERNALREGEX=0` 及 `RAPIDJSON_SCHEMA_USE_STDREGEX=1`。若你的 schema 无需使用 `pattern` 或 `patternProperties`，可以把两个宏都设为零，以禁用此功能，这样做可节省一些代码体积。
+
+## 性能
+
+大部分 C++ JSON 库都未支持 JSON Schema。因此我们尝试按照 [json-schema-benchmark](https://github.com/ebdrup/json-schema-benchmark) 去评估 RapidJSON 的 JSON Schema 校验器。该评测测试了 11 个运行在 node.js 上的 JavaScript 库。
+
+该评测校验 [JSON Schema Test Suite](https://github.com/json-schema/JSON-Schema-Test-Suite) 中的测试，当中排除了一些测试套件及个别测试。我们在 [`schematest.cpp`](test/perftest/schematest.cpp) 实现了相同的评测。
+
+在 MacBook Pro (2.8 GHz Intel Core i7) 上收集到以下结果。
+
+|校验器|相对速度|每秒执行的测试数目|
