Knowledge Graph Exploration for your end-users (and for you !)

Get Started

About Sparnatural

Sparnatural is a Typescript component that allows users to explore an RDF Knowledge Graph
by building SPARQL queries intuitively. It is configurable to adapt to your knowledge graph ontology.

How do you explore your knowledge graph ?

Maybe you have lists of entities. Or a search engine. Maybe you have facets. Maybe you even have data-visualisation. But can you explore your knowledge graph really as a graph ? This is what Sparnatural does.

Have you ever been frustrated by not being able to show - and to sell - all this nice structured data you have aggregated in your graph ? Sparnatural can demonstrate the value of heterogeneous data integration.

Are you looking for a solution that can bring your knowledge graph to your end-users ? Sparnatural is the right tool for this : it allows try-and-error interactions, it is visual, and it "gamifies" the knowledge graph experience.

End-User interface for your SPARQL endpoint

Adapt to your ontology

Sparnatural can be configured to adapt to your graph structure. You can hide some of the complexity of your graph, and simplify the navigation for your users. Configuration is made through an OWL ontology, fully documented.

Client-only (no additionnal server required)

Sparnatural is pure client javascript and can be plugged to any existing SPARQL endpoint, without additionnal server required.

Free and open-source

Sparnatural license is LGPL-3.0, which means you are free to integrate it in your website. Any modification you make inside the source code of Sparnatural needs to be distributed with the same license, or contributed to the original project.

Open-Source on Github

Sparnatural development is open and happens on the Github repository.

Fully customizable

Sparnatural offers different widgets for value selection : dropdown lists, ordered by occurrence count or alphabetically, autocomplete search fields, date pickers, tree widgets... this is all part of Sparnatural configuration.

Fully documentated

Sparnatural comes with complete documentation.

Make your own Sparnatural demo page

You can easily build your own demo page from our template in 4 steps. The only prerequisite is to know a SPARQL endpoint URL to which the generated queries will be sent.

1 - Create your configuration Spreadsheet

Build a new Google Spreadsheet using our template. Click the button below to copy the template to your own Google Drive account.
Your will use this spreadsheet to configure the classes, properties, icons, etc. of Sparnatural. More detailled documentation will come on how to fill in the spreadsheet.

Get the Spreadsheet Template

2 - Share your Spreadsheet

Once filled in, your spreadsheet needs to be publicly visible. You need to share it with the "Anyone with the link = Viewer" option. To do this, select the option Share.

After you close the window, copy the URL in your browser's address bar. You'll use this in the next step.

3 - Generate your Sparnatural demo page

Copy/paste the Google Spreadsheet URL into the first field below. Enter the URL of your SPARQL endpoint in the second field. Then press the Generate button to generate the URL to your demo page.


4 - Share Link

    (fr) 17/06/2022 - Restitution du projet Sparnatural : un outil pour explorer des graphes de métadonnées culturelles

    (fr) Les Archives nationales, la BnF et le département du Numérique pour la transformation des politiques culturelles et l’administration des données [DEPNUM] du ministère de la Culture se sont associés en 2021 pour mener à bien un projet visant deux objectifs :

    • 1) développer une nouvelle version de Sparnatural, un éditeur open source de requêtes SPARQL (qui est le langage utilisé pour faire des recherches dans des graphes RDF) ;
    • 2) mettre en place deux démonstrateurs web pleinement opérationnels, pour permettre l’exploration et la recherche intuitives dans des graphes de métadonnées culturelles grâce à des interfaces construites à l’aide de cet outil.

    Le projet a été réalisé dans le cadre d’un marché public confié à la société Sparna. La BnF (les responsables de a donc construit avec Sparna un démonstrateur web pour interroger l’ensemble de ses données RDF, soit tout le contenu de Les Archives nationales (le Lab, en concertation avec le département du Minutier central des notaires des Paris) ont construit avec Sparna un démonstrateur web qui permet d’interroger les métadonnées décrivant un tiers des archives notariales conservées aux Archives nationales, qu’elles ont préalablement converties en RDF conformément à l’ontologie RiC-O.

    Les supports de la restitution sont disponibles en téléchargement :
