Apache JENA

Apache JENA provides APIs for Semantic Web and linked data applications. It features ARQ, a SPARQL 1.1. compliant engine.

What is OpenRDF Better Known as?

RDF hackers will know about OpenRDF, which officially became Eclipse RDF4J in May 2016. 

Its tagline is its power to "create applications that leverage the power of linked data and Semantic Web".

Sesame was another name for what is now known as RDF4J.

Many name changes were also effected in the move to a new governance structure. For example:

org.openrdf.*  Java packages moved to org.eclipse.rdf4j.*

In particular the RDF4J project houses the SAIL (Storage and Inference Layer) API for low level transactional access to RDF data. Sail is dubbed the "JDBC of the RDF database world".

What is THE Semantic Web Stack?

The Semantic Web Stack illustrates the architecture of the Semantic Web.

Another weird name for this is Semantic Web Cake or Semantic Web Layer Cake.

It's built from hypertext technologies (such as XML, XML namespaces) and utilizes middle layer technologies like RDF and SPARQL (which is a middle layer RDF query language).

Security layer and UI layer are evolving areas of Semantic Web technology which are not standardised.
