This repository aims to provide a generic web platform to serve and manage RDF data.

It is a Django application backed by RDFLib-SQLAlchemy on a Postgres database.

The repository works with Docker and can provision resources via docker-compose. This is the recommended approach, although it is possible to follow a normal Django setup process as well. To start with Docker:

Make sure Docker is installed and the Docker daemon is running.

Clone the repository and cd into the directory you cloned to.

From here, you want to build your images, which could take a while:

$ docker-compose build

Now you're ready to bring up the services in daemon mode:

$ docker-compose up -d

Your application is listening on port 80 of your Docker default machine, e.g., http://192.168.99.100/

Run your migrations:

$ docker-compose run web python manage.py migrate

Create a superuser:

$ docker-compose run web python manage.py createsuperuser

And load your files. While the non-Docker startup will let you load from the local filesystem, in the Docker startup, you will need to specify a URL:

$ docker-compose run web python manage.py loadstor http://path.to/some/rdf.ttl graphname

If you want to use the admin and have it look pretty, you will want to collect the static files:

$ docker-compose run web python manage.py collectstatic --noinput

If all went well, you should be able to navigate to, e.g., http://192.168.99.100/admin and login as the superuser you made. Since there are no public endpoints, all management is done in the admin.

I have added my own supplementary managed models (the RDFLib-SQLAlchemy models are unmanaged) that hold unique lists of, e.g., Resources, OWL Classes, Predicates, and such. For instance, the contextualized triple

(s,p,o,c) (ns1:Foo,rdf:type,owl:Thing,context); 

would have an entry in the Resource model for ns1:Foo, an entry in the Predicate model for rdf:type, an entry in the Klass model for owl:Thing, and an entry in the Context model for context.

These are the things I think I still need to do, but I haven't fully evaluated all of them.

1. Create a basic HTML (non-admin) interface for viewing graphs and browsing by rdf:type.
2. Build out non-HTML views like JSON-LD, RDF/Turtle, and RDF/XML.
3. Search.
