        "description": "[![CircleCI](https://circleci.com/gh/evernym/sgl.svg?style=svg)](\nhttps://circleci.com/gh/evernym/sgl)\n\n# SGL (Simple Grant Language)\n\nSGL is a simple but flexible [DSL](\nhttps://en.wikipedia.org/wiki/Domain-specific_language) for matching people against criteria (typically, authorization). It is like [XACML](\nhttps://en.wikipedia.org/wiki/XACML) but simpler and JSON-oriented. You\ncan use it to write rules about who should be able to do what, and then\nto compare circumstances to the rules to enforce custom logic. This lets\nyou create your own [Role-Based Access Control](\nhttps://en.wikipedia.org/wiki/Role-based_access_control)\nmechanisms, as well as authorizations based on other criteria.\n\nFor example, here's an SGL rule that says only members of the press\nshould be allowed backstage at a concert:\n\n```JSON\n{\"grant\": [\"backstage\"], \"when\": { \"roles\": \"press\" }}\n```\n\nAnd here's how you might use that rule in python code. (Compare the [JavaScript/Node.js equivalent](https://github.com/evernym/simple-grant-lang/blob/master/README.md)):\n\n```python\nfrom sgl.api import satisfies\n\nmy_rule = {\"grant\": [\"backstage\"], \"when\": { \"roles\": \"press\" }}\n\npeople = [\n    {\"id\": \"Alex\", \"roles\": [\"ticket-holder\"]},\n    {\"id\": \"Sofia\", \"roles\": [\"ticket-holder\", \"press\"]}\n]\n\nfor person in people:\n    name = person['id']\n    if satisfies(person, my_rule):\n        print(f\"Welcome backstage, {name}.\")\n    else:\n        print(f\"Sorry, this area is restricted, {name}.\")\n```\n\nIf you ran this code, you'd see:\n\n```bash\n$ python sample_code.py\nSorry, this area is restricted, Alex.\nWelcome backstage, Sofia.\n```\n\nSGL supports arbitrarily complex rules with boolean operators, as well\nas rules that require multiple people to jointly exercise a privilege.\nHowever, it's simple enough that you should be able to learn it in just\na few minutes. See the [tutorial](\nhttps://evernym.github.io/sgl/docs/tutorial.html).\n\n>Note: SGL can be [rendered in various styles](\nhttps://evernym.github.io/sgl/docs/renderings.html). The example above\nuses the recommended JSON rendering, since JSON is familiar, broadly\nsupported, and easy to read. Other possibilities include ProtoBuf,\nMsgPack, CBOR, XML, and human-friendly text.\n\nSGL is not integrated with any particular enforcement mechanism, because\nit's designed for problems where you have to do your own enforcement.\nHooking it up to enforcement mechanisms is trivial, though.\n\n## See also\n* [Tutorial](https://evernym.github.io/sgl/docs/tutorial.html)\n* [Reference](https://evernym.github.io/sgl/docs/reference.html)",
