Asking valuable questions
Q: Give me all the 5th C open-vessels found at the site
#DigitalHumanities
Q: Did any occur alongside ash deposits?
Q: Give me the weights of the animal bones found in each of these contexts
Et cetera

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
