This project contains an engine for running DKAL policies. It is implemented primarly in F#.\n\nTry DKAL online in your browser: [http://www.rise4fun.com/dkal](http://www.rise4fun.com/dkal)\n\n## News\n* +2014/09/01+:\n\t* New paper about SPIL - [\"Primal Infon Logic with Conjunctions as Sets\"](http://research.microsoft.com/en-us/um/people/gurevich/Opera/221.pdf) published in [TCS2014](http://www.easyconferences.eu/tcs2014/).\n* +2014/05/04+:\n\t* SPIL [Logic Engine](\u003cdocs/Logic Engines.md\u003e) now is based on new [randomized algorithm](http://dkal.codeplex.com/SourceControl/latest#ModularEngine/src/LogicEngine.PPIL/SPIL.fs) with O(N) average complexity for all inputs.\n\t* Previous SPIL Logic Engines implementations are available on names \"SPILsufarr\" and \"SPILhash\"\n\t* [http://www.rise4fun.com/dkal](http://www.rise4fun.com/dkal) updated.\n* +2013/9/1+:\n\t* New [Logic Engines](\u003cdocs/Logic Engines.md\u003e)!\n\t\t* UFOL engine allows for expressing rules and actions in the universal fragment of First Order Logic; most noticeable is the ability to use negation and disjunction operators.\n\t\t* Datalog engine takes advantage of translating PIL to Datalog using Z3 as a backend (and in the future, XSB as well)\n* +2012/10/21+:\n\t* [release:DKAL v1.0.0.613 released](96609)\n* +2012/8/29+:\n\t* Try updated DKAL with syntax highlighting on [rise4fun](http://www.rise4fun.com/dkal)\n\t* New Propositional Primal Infon Logic based [Logic Engines](\u003cdocs/Logic Engines\u003e): BPIL, SPIL, TPIL\n\t* You can select logic engine in first line of [multi-policy file](SyntaxMultiPolicy).\n\t* [Quantified Infon Terms](SyntaxBasic#syntaxBasicQuant) (\"forall\")\n\t* 'do once' construct was removed. [Knowledge Assertions](SyntaxBasic#syntaxBasicKA) ('knows') introduced instead.\n\t* 'Me' principal constant renamed to 'me'\n\t* 'substrate' keyword renamed to 'datasource'\n* +2011/6/9+: We added lots of [developer documentation](DeveloperDocumentation).\n* +2011/6/6+: [release:DKAL v1.0.0.364 released](67844)\n* +2011/6/6+: Try out DKAL live on [rise4fun](http://www.rise4fun.com/Dkal)\n\n## Documentation\nFor a quick start on how to use DKAL, please refer to our documentation on:\n* [Obtaining DKAL](docs/ObtainingDKAL.md)\n* [Compiling DKAL](docs/CompilingDKAL.md)\n* [Using DKAL](docs/UsingDKAL.md)\n* [DKAL syntax](docs/Syntax.md)\n* [DKAL examples](docs/Examples.md)\n\nOtherwise, if you plan to extend or modify the DKAL engine, please visit our [developer documentation](docs/DeveloperDocumentation.md) section.\n\n## DKAL Challenges\nWe have collected a [list of interesting theoretical and practical challenges](docs/Challenges.md) related to DKAL and its underlying infon logic.\n\n## Underlying Theory\nMore information about DKAL, and its underlying theory, please visit our section on [suggested reading](docs/SuggestedReading.md), or go directly to [Yuri Gurevich's web page on the topic](http://research.microsoft.com/en-us/um/people/gurevich/dkal.htm).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Famelentev%2Fdkal","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Famelentev%2Fdkal","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Famelentev%2Fdkal/lists"}
