This document summarizes a presentation on accessing the benefits of open data practice within archaeology. It discusses converting archaeological data from a FileMaker database into a structured RDF format to create linked open data. It also describes using tools like the RDF Data Utilities and OpenRefine to clean, map, and publish the structured data online for access and analysis through SPARQL queries. The goal is to make more archaeological data openly available and interconnected on the web.
