Based on recent results, we argue that the right method for Web clients to access relevant information from Linked Datasets has not yet been found. We propose that something is needed between (i) Linked Data dereferencing, which is simple and reliable but too vaguely dened; (ii) data dumps, which are simple and reliable but too coarse-grained, and (iii) SPARQL querying, which is powerful and ne-grained but too unreliable. We argue that new protocols and query languages need to be investigated and dene eight desiderata that an access method should meet in order to be considered sustainable for a mature Web of Data. A reader familiar with the Linked Data literature will already know about the hundreds of Linked Datasets published on the Web: they are mentioned in the introduction to almost every research paper written in the area. They will likewise be familiar with the ubiquitous LOD Cloud, often cited as the realisation of a new emerging \Web of Data". They may even have read about hundreds of public SPARQL endpoints on the Web waiting to be queried or to be federated. 1
