Hi, I'm attempting to process ~250 XML files into RDF. I created a schema for the files using XMLSpy and imported the schema into TBC using the XSD importer. This created two .ttl files.
I created an SM script that iterates over the files using tops:files via a bind by select module. Prior to the Bind by Select, I import the schema ontologies and my target ontology. In the body, I import each XML file, convert it to RDF and then run a series of CONSTRUCT queries to map each file into the target ontology. The combination of all triples generated is then saved to disk. The script works fine if I only run through a small number of files. However, if I try to hit all 250 at once, it just runs slower and slower and slower... The slow part seems to be the CONSTRUCT queries. They run fast initially but slow significantly after 10-20 files. For every file that I have manually tested by running the CONSTRUCT query in the SPARQL view, the query has always run very fast so I do not know why performance is so poor running as an SM script. Any suggestions? Are there things I can do to speed this along? Is there data that I can collect to better inform you? My current work around is to process each directory individually but even that hits the problem because some directories have 10's of files (not to mention the obvious hassle of changing the script - file names, base URIs, etc... for each directory) I'm using 3.6B on win7/64 with 5G allocated to the JVM.
