How to Use in A Django App

[ImanoWilliams]

Hi, I have a Django application that user can query an ontology. I would like to know how I could visualize my ontology using Ontospy using Django. I see where there is Ontowebspy that is now archived.

Ontospy does not include any out of the box functionality for Django, but you can use the library like any other Python data processor.

For example

#
# in views.py
#

def ontology_page(request, uri=""):

    context = {}

    templatee = "my-ontology-template.html"

    # .. 
    # .. set ontospy opts
    # 

    g = Ontospy(
        URI, 
        verbose=verbose, 
        pref_title=preflabel, 
        pref_lang=preflang,
        hide_base_schemas=hide_base_schemas,
        hide_implicit_types=hide_implicit_types,
        hide_implicit_preds=hide_implicit_preds,
        hide_individuals=hide_individuals)

        context_data = {
            "topclasses": g.topclasses,
            "classes": g.all_classes,
            "properties": g.all_properties,
        # etc...
        }

    return render(request, templatee, context)

Then in the template you simply render the ontology properties using HTML. For example, see https://github.com/lambdamusic/Ontospy/blob/v1.9.9.1/ontospy/ontodocs/media/templates/html-single/html-single.html - this template is used by the ontospy gendocs command but that's basically a Django template..
