• legislation.gov.uk – 60k pieces of legislation for UK managed by the National Archives
• Publication in various formats – paper docs, pdf, xml, xhtml+RDFa, RDF
• TSO (The Stationery Office) currently redesigning workflows for legislation

Use cases/Requirements:

• Drafters of legislation (e.g. government departments) – “how is my job progressing though the publishing workflow?”
• Management information (aggregated) – “where are the bottlenecks in the publishing workflow”
• Maintainers may want to trace problems – “Which documents were derived from this XSLT?”
• Anyone might ask “Where did this document come from?”
• Acceptance test – re-run workflow from provenance graph (to prove that the provenance recorded is the true provenance – that re-running the same workflow results in the same outcome)
