Introduction

A Transformer Plugin for LarkC Project (http://www.larkc.eu). It supports mapping arbitrary ASCII and binary file formats to a data model defined in XML Schema using the XML-based Data Format Description Language (DFDL, forge.gridforum.org/projects/dfdl-wg/), and transforming the file content into RDF triples using Jena GRDDL Reader.

LarkC platform version: 2.0.0-SNAPSHOT http://www.wici-lab.org/wici/larkc/4eat/LarKC.rar

How it works:

1. Raw Text/Binary File + DFDL Description XSD File {DFDL Transforming}--> XML Data
2. XML Data + XSL File {GRDDL Transforming}--> Jena RDF Triples
3. Jena RDF Triples {Triple Transforming}--> OpenRDF RDF Triples

In summary, DFDLTransformer supports the following transformation:

Raw Text/Binary File + DFDL Description XSD File + XSL File --> OpenRDF RDF Triples

Example

Please check out the example in the "sample_data" directory:

• Workflow description file: https://dfdltransformer.googlecode.com/svn/trunk/DFDLTransformer/sample_data/DFDL-Workflow.rdf
• SPARQL query: https://dfdltransformer.googlecode.com/svn/trunk/DFDLTransformer/sample_data/DFDL-SPARQL.txt
• Expected results: https://dfdltransformer.googlecode.com/svn/trunk/DFDLTransformer/sample_data/expected_result.txt

You can also deploy the binary version into LarkC platform: https://dfdltransformer.googlecode.com/svn/trunk/DFDLTransformer/plugins/DFDLTransformer.larkc

LarkC platform version: 2.0.0-SNAPSHOT http://www.wici-lab.org/wici/larkc/4eat/LarKC.rar

Note that it's required to extract all the files from the "DFDLTransformer.larkc" package into the "plugins/DFDLTransformer", in order to run the example workflow.
