This presentation accompanies the paper that I gave at the European Association of Archaeologists 20th Annual Meeting, which was held in Istanbul on 10-14 Sep 2014. It describes the process of publishing the data of the Priniatikos Pyrgos archaeological project to the Semantic Web.

10. The 5 Stars of Linked Open Data
put your data online under an open license
make it structured (e.g. as an Excel file)
use non-proprietary formats (e.g. XML and not Excel)
use URIs to identify resources
link your data to external datasets

@flynam #DigitalHumanities
28 of 29 Q: Did any occur alongside ash deposits?
Q: Give me the weights of the animal bones found in
each of these contexts
Et cetera

30. Conclusions
1. Going Linked Open Data presents a number of
options and challenges
2. Making an archaeological dataset LOD-compliant is
not a trivial matter
3. But the rewards far outweigh the costs both in the
short term for your own project data needs and in
terms of making your project data relevant in the
years to come
