Recent research in a variety of settings (databases and data warehouses, geographic information systems, scientific workflows, grid computing, and the Semantic Web) has addressed the problem of keeping track of metadata about creation and modification history, influences, ownership, and other provenance or lineage information. Such metadata is essential for making informed judgments about data quality, integrity, and authenticity. In addition, ideas about provenance are now being used in several areas of computer science such as probabilistic databases, operating systems, file synchronization, and annotation propagation. Other topics, such as version control and archiving, may also benefit from better understanding of provenance. We believe the time is ripe to develop the foundations of the topic and address questions such as:
- What does it mean for information to be "provenance"? What is and what isn't provenance?
- What kinds of problems does provenance address, and how does one characterize correct solutions?
- How does one compare different models of provenance?
- Why is provenance so hard to get right, even though it seems rather obvious?
- Where should research efforts be focused to make the best progress?
Following an earlier informal meeting in June at the University of Pennsylvania, we organized this workshop with the goal of bringing together researchers from different backgrounds (including databases, scientific data & workflow management, and programming languages) interested in principles of provenance.

There is no registration fee. However, registration is appreciated so that we can plan appropriately for coffee/tea breaks and possibly organize a workshop dinner. Please contact James Cheney (jcheney at inf dot ed dot ac dot uk) to indicate that you will attend.
Traveling to Edinburgh
By air. Edinburgh International Airport (EDI) is the most convenient way to get to Edinburgh by air. There is a frequent and relatively inexpensive (£5 round-trip) express bus that runs between central Edinburgh (where the workshop venue and most of the suggested places to stay are) and the airport.
Glasgow Airport (GLA) is not very far away but public transportation connections are not very good to Edinburgh from Glasgow airport (there is no direct rail link).
By rail. If traveling to Edinburgh by rail, depending on where you are staying either Waverley or Haymarket station should put you within 10-15 minutes' walking distance of the conference venue or hotel.
Venue and Accommodation
The workshop will take place in Edinburgh at the International Centre for Mathematical Sciences on 19-20 November. ICMS is in downtown Edinburgh, in the New Town, and is within walking distance of several hotels or B&Bs. The ICMS web site has maps and travel information, and accommodation information that may be helpful for workshop participants.
