For generating Microdata or RDFa Lite 1.1 semantics you can use the PHP library . Created during the Google Summer of Code 2013 and 2014. (**Deprecated**) Documentation ------------- [](#documentation) #### Files structure: [](#files-structure) - `configuration.php` → the configuration file, setup the type of library to be created. - `http.php` → a class that handles all HTTP requests. - `parser.php` → methods to parse the HTML and retrieve all needed information. - `fileCreator.php` → methods to create the library files. Usage ----- [](#usage) - Make sure you have the cURL library installed, and the PHP CLI shell script package - Clone the repo: git clone - Enter `Spider4Schema/` directory - Open your `terminal/shell` and call `php bin/spider.php [minified|json|normal] [true|false|verbose]` The libraries will be created in the `dist/` folder. Library types ------------- [](#library-types) There are 3 types of libraries you can create: - JSON → a .json file containing all available Types and Properties, used in library for generating valid Microdata and RDFa Lite 1.1 semantics - Minified → a .php file with an array containing all available Types and Properties - Normal → each Type is a PHP class file (an abstract class with static Properties) Performance ----------- [](#performance) The **json** library: 1 .json file, 91 KB, contains all available Types (620+) and its Properties The **minified** library: 1 php file, 107 KB, contains all available Types (620+) and its Properties, stored in a hash table (array) The **normal** abstract static library: 622 php files, 710 KB, 1 file for each available Type Todos ----- [](#todos) - Add to the all the required properties specified by Google, Yandex, Baidu. - Instead of making 620+ HTTP requests, parse one file: [https://schema.org/docs/schema\_org\_rdfa.html](https://schema.org/docs/schema_org_rdfa.html) - Write tests.
