Incorporating the Semantic Web into Java

I want to propose that we incorporate the Semantic Web technologies as a
core part of Java. The Semantic Web and object-oriented programming are
very compatible and can work very well together. I have always believed
there is a lot of value in the Semantic Web, and I believe that it would
be very beneficial for Java to incorporate the Semantic Web in the
manner I have in mind.
This is my first post here. I thought this mailing list might be the
best place to post. I recently signed the Oracle Contributor Agreement.
People have always noted connections between object-oriented programming
and the Semantic Web, such as in the introduction to the Semantic Web at
, which you could read if you are not familiar with the Semantic
Web. I believe that we should integrate the two technologies more closely.
I have written a large piece of software towards using the Semantic Web
in Java . I would be very pleased to contribute any of this code to
OpenJDK, if you think it would be worthwhile. The software allows us to
give IRI's and semantics to Java classes and attributes using Java
annotations. For example, here is the isDefinedBy.java file for the
isDefinedBy property in the RDFS ontology:
@comment("The definition of the subject resource.")
public @interface isDefinedBy
public String value();
We can treat Java classes as unary predicates, as in the Semantic Web,
and Java attributes as binary predicates relating two entities, as RDF
properties. Then we can use the OWL reasoning in Java programs in a
manner that is fully compatible with Java, and we can make Java data
into linked data so that we can run SPARQL queries on the data and post
the data on the Semantic Web.
My software is a Java library intended to be useful in writing Java
programs in general. I published an article about the ideas in 2014
, and I explain more what I am thinking on the front page of the
software's web site.
The Semantic Web is a mature set of technologies. Mostly what we would
need to do is connect existing reasoning and SPARQL algorithms to Java.
I have written the framework for doing so.
I hope you find these ideas interesting. I would very much like to work
together with other people on developing software towards these goals.
Functional programming was a great addition to Java 8, and I think the
Semantic Web would be a great addition to Java 9 or 10.
