Open Provenance Model Tutorial Session 4: Use cases from data.gov.uk Jun Zhao University of Oxford [email_address]

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
