graffl 0.9.0

A simple syntax for RDF.

(pronounced g-raffl, but also derived from the Bavarian word "Graffl" meaning "stuff" or "junk")

Summary

graffl is a (still) experimental RDF scratch pad file format. Its purpose is to write something down that is immediately understood as graph data. No annoying syntax like dots or commas is required. Think of it as Markdown for RDF.

For example, the following graffl graph:

Alice likes -> Bob

written as Turtle:

@prefix ns1: <https://www.hedenus.de/graffl/76a04f61-342e-11f1-a289-e08f4ccbe174/> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .

ns1:Alice rdfs:label "Alice" ;
    ns1:likes ns1:Bob .

It also supports OWL modeling and nested graphs!

See the documentation docs/graffl.adoc.

See the src/graffl/graffl.lark file for the EBNF grammar.

The parser is implemented as an extension for rdflib: https://github.com/rdflib/rdflib

The file format is used by rdf2graphml: https://github.com/mhedenus/rdf2graphml

CLI

The CLI command graffl converts one or more *.graffl files to TriG:

graffl [-h] [-V] [-o OUTPUT] [-v] [-d INPUT_DIR] [input_files ...]

The produced RDF is merged in one dataset. You can separate the graphs using the @context directive. If no output is specified, the result is printed to standard output.
