Zusammenfassung: | The ability to calculate hash values is fundamental for using cryptographic tools, such as digital signatures, with RDF data. Without hashing it is difficult to implement tamper-resistant attribution or provenance tracking, both important for establishing trust with open data. We propose a novel hash function for RDF graphs, which does not require altering the contents of the graph, does not need to record additional information, and does not depend on a concrete RDF syntax. We are also presenting a solution to the deterministic blank node labeling problem. |
