Lewis John McGibbney commented on ANY23-504:
--------------------------------------------
In this case the extractor was an [instanceOf
ContentExtractor|https://github.com/apache/any23/blob/2a5b41acccfbb04de62824f1375d74c490071343/api/src/main/java/org/apache/any23/extractor/Extractor.java#L44]
https://github.com/apache/any23/blob/master/core/src/main/java/org/apache/any23/extractor/SingleDocumentExtraction.java#L520-L524
We could augment the application-level configuration in
[default-configuration.properties|https://github.com/apache/any23/blob/master/api/src/main/resources/default-configuration.properties].
I've not yet pinned down exactly how this could be implemented seeing as the
underlying parse implementation is
[org.eclipse.rdf4j.rio.trix.TriXParser|https://rdf4j.org/javadoc/latest/index.html?org/eclipse/rdf4j/rio/trix/TriXParser.html].
Any23 RDF Parsers are configured in
[RDFParserFactory.configureParser(...)|https://github.com/apache/any23/blob/master/core/src/main/java/org/apache/any23/extractor/rdf/RDFParserFactory.java#L278-L305].
The other observation... should the TrixParser really have been activated here?

> The Any23 parser should optionally avoid to open HTTP connections when

> While testing the Nutch's Any23 plugin with 2.5 (NUTCH-2892) on the file
> "BBC_News_Scotland.htm", the parser did hang for about two minutes with an
> open HTTP connection to "hans-moleman.w3.org" and the following stack:
