Open Provenance Model Tutorial Session 4: Use cases from data.gov.uk

Outline

• Background about data.gov.uk• The use cases– XML serialization– Data transformation on the fly– Complex and nested processes

data.gov.uk

• Linking UK government data• Aims:– Provide a set of best practices for government

agencies– Provide the minimum set of tooling and

specification to facilitate the publication of data– Encourage “responsible” data publishing

Non-digital Data Objects

• Organizations– Organizational structure changes over time– Origin organization, resulting Organization

• Boundary• Legislation

An organization ontology: http://www.epimorphics.com/public/vocabulary/org.html

The Challenges

• Data of different representations, of physical forms, of granularity

• Not tooling support• Provenance across different types of systems– Identification– Different terminologies

The Gaps

• A vocabulary being able to describe provenance of all types of data, from different systems

• A vocabulary still providing enough terms to describe provenance accurately
