digrdf 0.1.4

RDF Schema Diagram creation tool

Diagrammer

Generates Schema Diagrams from RDF

Dependencies

• ARQ - A Sparql Processor for Jena

Only required to query local files

TODO: Fallback to rdflib if sparql is not available. Currently not implemented because of performance issues.

Installation

pip install digrdf

Usage

from the command line

python -m digrdf -i myfiles/

This will create a file called diagram.html in the working directory and open it for viewing.

You can query any sparql endpoint as well.

python -m digrdf -i "http://myserver.com/sparql"

This will generate a schema diagram for all triples at that endpoint.

warning The query is intensive and may crash / timeout if the triple store has a lot of triples (like 1.0GB plus)

You can also generate an instance level diagram for a particular iri

python -m rdflib -i "http://myserver.com/sparql" -s "http://myserver.com/objects/1234"

where -s or --subject is a valid iri for an object in the triple store

To see all the cmdline options run

python -m digrdf -h
