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.
