Simple Linked Data Deployment using RDF-Turtle Documents
A post about a simple approach to deploying RDF documents using Linked Data principles, courtesy of RDF-Turtle documents.
Linked Open Data (LOD) Cloud
A Web of Data comprising Entity Description Documents created using RDF that have been deployed using Linked Data principles. The key defining characteristics of this kind of Web are: 1) every entity (thing) is identified using a hyperlink (specifically, HTTP URI); 2) every entity is described using structured RDF sentence collections where a hyperlink identifies the subject and predicate, while a hyperlink or literal (typed or untyped) identifies the object.
Simple Linked Data Deployment using JSON-LD Documents

What are Virtuoso's Sponger Middleware layer Extractor and Meta Cartridges?
<p>A post that describes Virtuoso's Sponger Middleware Module. This module comprises a variety of Cartridges (Data Access Drivers or Connectors) that perform Extract, Transform, and Load (ETL) operations on a variety of Web-accessible Data Sources (or Resources). Cartridge Types include:</p> <p>Extractor Cartridges -- these perform basic Extract, Transform, and Load operations on target Data Sources (just like ODBC or JDBC Drives, but the end product produces Structured Data Represented as Knowledge Graphs rather than Tables).</p> <p>Lookup-up Meta Cartridges -- these perform additional Knowledge Graph enhancement by looking-up and incorporating additional Structured Data to the progressively enhanced local Knowledge Graph from the massive LOD Cloud and other sources (e.g., the local host DBMS instance and other Virtuoso or SPARQL-accessible Data Sources).</p> <p>Named Entity Extraction (NER) and Natural Language (NLP) Meta Cartridges -- that perform NER and NLP operations on the data transformed by Extractor Cartridges en route final storage in the progressively enhanced local Knowledge Graph managed by a Virtuoso DBMS instance.</p>

Why Should I Pay for ODBC or JDBC Drivers (Connectors)?
A post about characteristics that differentiate Free ODBC and JDBC Drivers from their commercial equivalents. It covers important areas such as: <ul> <li>Security -- using a sophisticated profile matrix to control data access based on user identity, machine identity, application identity, ip address, or any combination of the aformentioned combined with additional custom factors, if need be</li> <li>Application Support -- exploit the power and promise of open data connectivity using a wide variety applications rather than a select few; features like scrollable cursors offer sophisticated functionality in a variety of forms (keyset or dynamic) that ultimately affect application behavior and cost-effectiveness</li> <li>Performance & Scalability -- ensuring that performance and scalability are never impediments to open data connectivity exploitation</li> <li>Flexible License -- paying for the value provided by way of sophisticated licensing, based on CPU Affinity (rather than all the CPUs available in a given host machine) and concurrent users.</li> </ul>

Virtuoso provides a one-click option, as part of its RDF Views Wizard for generating a basic Linked Data view over Tabular Relations (Tables) scoped to local or remote data sources. As is the case in a conventional SQL RDBMS usage scenario, these views provide a change-sensitive abstraction for operating on data via the SPARQL Query Language. This feature enables both beginner and advanced users alike to experience enhancements that a Semantic Web of Linked Data brings to Data Flow and Interaction with a minimal learning curve.
