Reference Rot denotes the combination of both effects. Spatial metadata records rely on hyperlinks for indicating the location of the resources they describe. Therefore, they are also subject to Reference Rot. This paper evaluates the presence of Reference Rot and its impact on the 22,738 distribution URIs of 18,054 metadata records from 26 European INSPIRE spatial data catalogues. Our Link Rot checking method detects broken links while considering the specific requirements of spatial data services. Our Content Drift checking method uses the data format as an indicator. It compares the data formats declared in the metadata with the actual data types returned by the hyperlinks. Findings show that 10.41% of the distribution URIs suffer from Link Rot and at least 6.21% of records suffer from Content Drift (do not declare its distribution types correctly). Additionally, 14.94% of metadata records only contain intermediate HTML web pages as distribution URIs and 31.37% contain at least one HTML web page; thus, they cannot be accessed or checked directly. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.4 2022 GEOGRAPHY, PHYSICAL 18 / 49 = 0.367 2022 Q2 T2 COMPUTER SCIENCE, INFORMATION SYSTEMS 88 / 158 = 0.557 2022 Q3 T2 REMOTE SENSING 21 / 34 = 0.618 2022 Q3 T2 0.738 2022 Earth and Planetary Sciences (miscellaneous) 2022 Q1 Geography, Planning and Development 2022 Q1 Computers in Earth Sciences 2022 Q2 6.2 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Lopez-Pellicer, Francisco Javier Universidad de Zaragoza (orcid)0000-0001-6491-7430 Nogueras-Iso, Javier Universidad de Zaragoza (orcid)0000-0002-1279-0367 Lacasta, Javier Universidad de Zaragoza (orcid)0000-0003-3071-5819 Zarazaga-Soria, Francisco Javier Universidad de Zaragoza (orcid)0000-0002-6557-2494 5007 570 Universidad de Zaragoza Dpto.
