Since some of the landing pages and online triple stores for the Amsterdam Museum Linked Data set were no longer available, I copied the original data to a GitHub repository. https://github.com/biktorrr/AHM
This dataset is the result of a conversion of the Amsterdam Museum collection database, and structured vocabularies into Linked Data in the Europeana Data Model (EDM). More information can be found in our dataset paper: https://www.semantic-web-journal.net/content/amsterdam-museum-linked-open-data
In the past (2011), the data was available int the Europeana Semantic Layer, developed by the EuropeanaConnect project. At this point, the original data is provided as is through this git repository only. If you want to use it, load it into your favourite triple store. This data has been used as a benchmark dataset in multiple Linked Data research projects, including the kgbench repository benchmark http://kgbench.info/ and therefore I feel it makes sense to ensure the original RDF data can be accessed.
