About
HAWS contains a set of libraries and code related with some semantic web projects that I am working on
The code is not production-ready and is mostly proof-of-concept
The source code contains:
- A purely declarative representation of RDF Graphs using Inductive Triple Graphs
- Operational semantics of Shape Expressions using a direct translation of the inference rules
and a backtracking monad
- Derivatives implementation of Regular Shape Expressions
-
Notice that the implementation of both Shape Expressions and Inductive RDF graphs don't contain
a parser yet.
By now, the only way to play with them is by declaring the triples/shapes by hand.
