#PATENTS RE-ENGINEERING
RDF-izer (Extractor) for patent XML documents.
##Stanbol Enhancement Engine
The outcome of this project is an OSGi bundle (enhancement engine) for Apache Stanbol that takes a patent document XML file as input and gives RDF triples as output. It uses an XSLT transformation to map the MAREC XML elements and attributes to classes and properties of a patent ontology as explained below.
The name of the engine is marecEngine. This same name must be used when configuring a chain in order to use it.
When called from a client using the REST API the bundle will send back the RDF data extracted.
XSLT 2.0 templates to transform MAREC XML to RDF/XML, ECLA to RDF/XML and supporting data.
An XSLT 2.0 processor to transform, and some configuring to change defaults.
Currently it does two types of transformations: patents and classifications. The patents are based on the MAREC standard which is a superset of the patents from EP, US, JP, WO offices. The classifications are based on ECLA (and soon to be on CPC).
From patents, it transforms bibliogrpahic-data, publication and application references, priority-claims, technical-data (classifications), parties (applicants, inventors, assignees), claims.
There is also a small script that converts a list of filing offices from the EPO websites into N-Triples.
Classifications and filing offices are both used in patents.
It comes with scripts and sample data. Tested with saxonb-xslt tool for Debian from command-line.
The scripts/ directory contains Bash script to test on sample data.
The xsl/ directory is for MAREC and ECLA transformations.
There is some sample data under data/.
Either use the provided Bash script for sample data, or take marec.xsl, common.xsl to your application. Run marec.xsl (it imports common.xsl). Same goes for ecla.xsl.
