VirtuosoRDBMS SPECIAL Project

[Sonja Heward-Mills <snevitt@openlinksw.com>]

Hello Sabrina

I understand you are the Scientific Coordinator of SPECIAL project and 
maybe interested in some commercial features of Virtuoso 8.x  - in 
particular Enhanced security (ABAC)

I can see in the project plan some features that are key which are 
available in the Commercial Edition of Virtuoso ie:

secure workflows that include usage/access control, robustness in terms 
of performance, scalability and security all of which are necessary to 
support privacy preserving innovation in Big Data environments

https://www.specialprivacy.eu/about/project-plan

Virtuoso is a multi-model RDBMS that supports RDF as one of its Data 
Definition Languages (DDL), SPARQL as a Data Definition, Data 
Manipulation (DML), and Reasoning & Inference Rules Languages is 
inescapably vital to any modern Digital Transformation endeavor.

As the following benchmark reports demonstrates, our Virtuoso RDBMS has 
slayed all performance and scalability demons, while also addressing the 
Data Security and Data Virtualization issues that are generally 
overlooked (even in this era of GDPR).

Latest benchmark report that compares Virtuoso 7.x and the latest 
Virtuoso 8.x releases: https://lnkd.in/eCQKVhm

What are the key feature differences b/w Virtuoso 7.x and 8.x?
SPARQL as a Rules Language and highly-scalable Attribute-based Access 
Controls (ABAC) for security are features of 8.x.


I hope this information is helpful and that you will highly consider 
Virtuoso 8.x as a solution for the SPECIAl project.

Regards

Sonja
