[Moose-dev] Re: [Pharo-project] Resource Descriptor Framework

Is there much being done with Resource Description Framework in Squeak/Pharo? I have some RDF data files that I need to load for my masters project and am seeking advice on how to approach this. I am only just learning about RDF for the first time. For anyone else interested the best short overview I found so far is [ http://logicerror.com/semanticWeb-webdev ] Apparently it this is a Simplified RDF Syntax as described at [ http://www.langdale.com.au/CIMXML/PSModelExchange.pdf ] A data file looks like like this... <?xml version="1.0" encoding="UTF-8"?> <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:cim="http://iec.ch/TC57/2007/CIM-schema-cim12#"> <cim:ACLineSegment rdf:ID="_7814201"> <cim:Conductor.length>95</cim:Conductor.length> <cim:IdentifiedObject.name>AMHE400MARCLINE</cim:IdentifiedObject.name> <cim:ConductingEquipment.BaseVoltage rdf:resource="#_400000302"/> <cim:Equipment.MemberOf_EquipmentContainer rdf:resource="#_487038201"/> </cim:ACLineSegment> The most obvious project on Squeaksource is Rakaiko [a] which says "RDF is an essential part of the new web technologies and a fundamental layer of the semantic Web 2.0 [...] This API, compliant with the W3C RDF specification will allow a developer to handle an RDF graph in its various forms (RDF/XML, N3, abstract graph). In other words, it would be the Squeak equivalent of the Jena Java RDF API." However there has been no activity on Rakaiko since 2007 and there is no apparent documentation. Has anyone used this and/or is this abandoned? Page 20 of "ESUG 2006 Welcome" mentions a "RDF Framework for Smalltalk." Did anything come of this? Alternatively I could fake it and learn just how to parse the XML directly and manually translate it into the class model. (It seems processing an a RDF Schema might be able to automatically create the class definition as well as the instance creation ) There is PetitXML, which however is not included by ConfigurationOfPetitParser.24 loaded on Moose 4.6. What is the status of PetitXML ? Also Moose 4.6 has XML-Parser. Which of XML-Parser or PetitXML would be the better approach ? I've watched http://www.tudorgirba.com/blog/simple-xml-browser-with-glamour but not sure whether than will help me actually load the data into a model. You opinion of these various approaches would be appreciated, and of course pointers to any examples/documentation.
