Formal semantics: All standards in the Semantic Web stack come with well-specified semantics, which allow humans and computers to interpret schema, ontologies, and data unambiguously.
Performance: All specifications have been malaysia whatsapp number data thought out and proven to allow for efficient management of graphs of billions of facts and properties.
Interoperability: There is a range of specifications for data serialization, access (SPARQL Protocol for end-points), management (SPARQL Graph Store), and federation. The use of globally unique identifiers facilitates data integration and publishing.
Standardization: through the W3C community process, to make sure that the requirements of different actors are satisfied –from logicians to enterprise data management professionals and system operations teams.
However, it’s important to note that not every RDF graph is a knowledge graph. For instance, a set of statistical data, e.g. the GDP data for countries, represented in RDF is not a knowledge graph. A graph representation of data is often useful, but it might be unnecessary to capture the semantic knowledge of the data. It might also be sufficient for an application to just have the string “Italy” associated with the string “GDP” and the number “$1.95 trillion” without needing to define what countries are or what the Gross Domestic Product of a country is.
