![]() Well, reading many errors on the forum I realized that I have encountered virtually all of them, and found a way around them. add recursivity by substituting matching triples in antecedent with theirĪs an exemple, think of a family relationship rule base (see rulesĮxamples - Family relationships ).Fiesta Online Troubleshooting Guide by The-Sakura.Substitute suitable variables with their constant value add recursivity by finding SWRL rules matching a simplified N3 query.This needs an RDF vocabulary for SPARQL queries, which can be SWRL So the roadmap for this SPARQL generation feature could be : Is suitable for writing rules by hand and proof-reading by developers (andĭirectly interpretation by any of the EulerGUI. to write the SWRL => N3 converter rules ). So SWRL just a quite simple RDF rule format, enough well documented (but Iĭin't have to reed the doc. Match rule parts when the rule is expressed as pure RDF graph (SWRL or other). (this is actually a problem when processing N3 with N3). There's no possible confusion between input rules and transformation rules Good thing with SWRL is, it's plain RDF, and as a consequence Since I already haveĮxperience with dealing with SWRL, it ' s probably quite easy to first convert I used to think that for point 2, the capabilities of Euler or CHR to handle We need to design and implement a backward engine for querying SPARQLĭatabases it will generate a big SPARQL query by recursively accumulatingĬriterium terms, substituting bound variables, renaming variables if The point 2 is necessary for automating access to Linked Open Data (see Roadmapįor EulerGUI 2.1, and Sketch of a roadmap / The Déductions Point 1 will stay like this in the near future, as current implementation is Query (an N3 expresion with triples including variables but no generate SPARQL queries from N3 rule base and a simplified N3.transform N3 rules into Drools rules (currently implemented by ad-hoc.We need to have more rules manipulating rules to : declare undeclared properties and classes in N3 rules.check N3 rules for undeclared properties and classes.We already have such rules manipulating rules to : And, because we buildīusiness applications using rules (applicative and infrastructure rules), this In fact business rules are raw material for the building of businessĪpplications just like ontologies and structural models. Rules are not only for business rules (generating SPARQL queries Inference, and for implementing stand-alone RDF file processors (usable in Swish is conceived as a toolkit for experimenting with RDF Language Haskell, for performing deductions in RDF data using a variety of Swish is a framework, written in the purely functional programming Ruset: there a link 'papers' in first link.
