This document discusses open data in archaeology. It defines open data as content or data that anyone is free to use, reuse, and redistribute, subject to attribution and sharing-alike requirements. The document outlines momentum for open data from open government initiatives and advocates for open licensing of archaeological data to increase impact and encourage reuse. However, it notes challenges including episodic and unsustainable open data efforts, lack of long-term preservation, balancing openness with cultural sensitivities, and avoiding "non-commercial" licenses that do not have clear definitions. Overall, the document promotes individual and institutional advocacy for open archaeological data standards and best practices.

if anyone is free to use, reuse,

at most, to the requirement to
attribute and share-alike"

12. Archaeological Data?

13. Open Archaeological
Data

14. Open Archaeological Data –
thedatahub.org

15. Open Archaeological Data
Episodic basis
Most (if not all) from US and UK
Slow “evangelisation” towards open licenses
Sustainability?
Long-term preservation?

16. Agenda
Individual and institutional advocacy
Ethics and consensus building
Knowledge transfer

17. Institutional advocacy
Funding
Publication
Open data as an integral part, not an after
thought
Individual advocacy
Higher impact ( ~ open access literature)
Peer pressure (domain specific)

18. Open data and interoperability
Data first, inter-project consistency later
Open licensing more important than rich
semantics?
Let's keep computer scientists busy!
One star is a star(t) ★☆☆☆☆
★ Available on the web (whatever format) but with
an open licence, to be Open Data

19. Consistency?

20. Open Data and archiving,
preservation
UK has a distorted perspective (ADS)
Countless projects in other countries do not
achieve even minimal standards of archiving
and preservation
Open data should be done independently
Open data may be a way of preservation by
dissemination (Archive.org, Google)

21. Chaotic, decentralised, open

22. Google Refine

23. Ethics - 1
Sharing data across sovereign borders
Risks of “Colonisation 2.0”
Grace periods? (EAA: 5 years)

24. Ethics - 2
Specialisation → Balkanisation
Archaeology → Archaeologies
Whom are we trying to convince?

25. Ethics – 3
Open data and the public
What does the public want?
Who is the public anyway?
Wikipedia
Wiki Loves Monuments
Wikipedian in Residence
What should not be public?

26. Ethics – 4
The case against “Non commercial” licenses
No clear definition
Commercial archaeology is vital and should not
be excluded

27. Knowledge transfer
Avoid producing closed data
Avoid mixing of closed and open data
Best practices
