For week ending Friday, 2019-09-20

DEMO - OpenLink Data Sniffer reveals that Deloitte is also putting Linked Data to practical use. For instance, their Jobs page deploys a Knowledge Graph via HTML using terms from the SchemaOrg Ontology
This post demonstrates practical use of RDF sentences embedded as StructuredData islands within HTML5 documents – a modern SEO or SSEO content deployment pattern.
Crowdsourcing request - Important effort that will make the unintentionally-stealthily-built LOD Cloud much easier to understand and exploit from a variety of perspectives
What does a Graph Database do differently from a conventional RDBMS?
Fun fact - You can share a SPARQL query from a Virtuoso SPARQL Editor instance by clicking on the “Permalink” hyperlink
Here is a cool OpenData effort created by Barcelona’s open data service team
SPARQL offers a wonderful SAMPLE() aggregate function for building cool indexes that aid follow-your-nose exploration via Linked Data docs.
Why is there a need to knock SPARQL when talking about GQL, Cypher, etc? A need to knock RDF DBMS and Stores when talking about a Graph Database, etc?
Q: Can I use both SPARQL and SQL as query languages for operating on data managed by a Virtuoso instance? A: Yes!
Basically, DBpedia, Wikidata, and other LODCloud data sets are accessible via ODBC, JDBC and dotNET
Linked Data is crucial to creating a Knowledge Graph that manifests as a Semantic Web, period. The “Web” in all of this refers to a Hyperlink-based Entity Relationship Graph that’s navigable by both humans and machines using de-reference (i.e., lookup).
OpenLink has opened up a new community forum channel focused on Linked Data with the sole aim of teaching anyone interested in this powerful concept through live examples.
Quote of the Week “Linked Data is like wine”
OpenLink Data Sniffer shedding a little more light on the wine-like nature of LinkedData, demonstrated by that page about UK Railways.
Another example that demonstrates why Linked Data is like wine: UK Ordnance Survey.
Live SPARQL queries demonstrating Entity Resolution informed by Relationship Type Semantics defined in an Ontology
