Question: Does anyone have a link to a live example on the Web of a non-RDF GraphDatabase that offers the equivalent of a single node in the massive LODCloud?
Open invitation for crowd-sourcing up-to-date list of query service endpoints that underlie the massive LOD Cloud Knowledge Graph
Virtuoso use case: ArCo Knowledge Graph Italian Cultural Heritage – query service for exploring the Entity Relationship Graph that represents how Entities are Related in this particular space.
OpenLink Virtuoso tech tip: Restoring from online backup on Windows
Can I use SQL to query DBpedia and other nodes in the massive LODCloud? Yes, that has been the case since we added SPARQL support to Virtuoso via SPASQL.
Use “vdb” as the username and pwd when challenged for credentials with regards to these live SPASQL (i.e., SPARQL inside SQL) demos. This is all about supporting two query languages in a Multi-Model DBMS for operating on Relations (N-Tuples and 3-Tuples).
Virtuoso Use case: Isidore Personal Data Assistant
What does a Graph Database do differently from a conventional RDBMS?
New features have been added to our Data Entry Application
What does an #RDF-compliant Graph Database do differently from alternatives?
New PostgreSQL Single-Tier (Lite Edition) ODBC Drivers for Linux are now available for Free Evaluation. Key features: Both iODBC & unixODBC compatible. Support for version 3.0 wire protocol (so works with Azure instances)
