This talk provides concrete tips on how to improve your open data accessibility and discovery. We use real world analysis of what Europe has today, rather than specifications, guidelines, or theory. We recently investigated the linkage between Metadata (CSW Dataset and Service Metadata records) and actual downloadable/viewable data (WFS, WMS, WMTS, and Atom). We also looked at other linkages between the documents (for example, metadata document links, "operatesOn" links, Inspire "ExtendedCapabilities", and other MetadataURL links). Following links isn't as simple as just taking the given URL and resolving it - we will look at "fixing" the URL as well as setting request headers. We will also investigate comparing two different metadata documents (from different URLs) to see if they are "the same" even if they aren't really equivalent. If you are responsible for an INSPIRE catalogue or web service, attend this talk to learn what works (and does not work) based on real world analysis rather than theory. Or just attend to be sure you did not show up in the examples.
