Introduction

We built this ontology by looking at log4j version 1.2 and version 2 beta: http://logging.apache.org/log4j/2.x/manual/layouts.html, http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html Is this complete? No! But it will be sufficient for most use cases, please feel free to extend and adapt the ontology, if you need more. Loglevels: TRACE, DEBUG, INFO, WARN, ERROR and FATAL Feedback If you'd like to leave feedback, please open an issue on GitHub (https://github.com/NLP2RDF/ontologies/issues) and read the README (https://github.com/NLP2RDF/ontologies#readme) or write an email to the mailing list: http://lists.informatik.uni-leipzig.de/mailman/listinfo/nlp2rdf Versioning process is explained here: http://persistence.uni-leipzig.org/nlp2rdf/specification/version.html Changelog: * 1.0.0 initial version * 1.0.1 added Error Code class and errcode property * 1.1.0 change Error Code class to Status Code
