Introduction

The Common Log Analysis Vocabulary (Logan) is a simple RDF vocabulary to model common log format server log entries, as well as some basic facts about SPARQL queries which might appear in such log entries. Each entry is represented as a logan:LogEntry. Logan makes use of external vocabularies: Agents are modelled as foaf:Agent instances, log entry dates are modelled with dcterms:created.
