From Spreadsheets to 5-star Linked Data in the Cultural Heritage Domain: A Case Study of the Yellow List
Audun Stolpe, Martin G. Skjæveland · 2011
This paper presents the results and lessons learnt from converting the Cultural Heritage Management Office in Oslo’s Yellow List of architecturally and culturally valuable buildings into a Linked Data server. The study was performed in the context of the Semicolon II project, as a foray into the more general problem of lifting public sector information. The paper argues, that whilst the benefits of adopting the Linked Data distribution model are many and important, the required transformation to RDF is not unproblematic. Specifically, one needs to ensure that the information content of a dataset is preserved undistorted despite the change of representation. This can not be assumed to be the case by default, since a transformation will often alter the very structure of the dataset. The paper draws attention to the concept of a bounded RDF homomorphism as a means to address this problem. 1
