RE: RDF Playground

Both are very impressive!

I’m especially fond of YATE’s namespace addition and auto-completion – just because I’ve often wanted / needed it in practice :-)

For Notation3, we’ve been working towards a simple JS editor<https://github.com/william-vw/n3-editor-js> (thanks to ANTLR’s JS compilation support).

It seems that, using LOV and prefix.cc, one could (relatively) easily implement support for working with namespaces in general RDF / N3 / SPARQL / .. editors.

Hi Aidan, Bastián,

This is a pretty useful resource for teaching, thank you !
For the Turtle syntax coloring, automatic namespace addition, and autocompletion, Would you consider reusing YATE ? https://perfectkb.github.io/yate/

Hi Aidan

That's very cool!

I'm wondering how hard it would be to implement similar functionality purely on the client. I've recently been experimenting with running YASGUI against a client-side store: https://retog.github.io/patchgraph/#/sparql


I think SHACL would be no problem on the client but I don't know about OWL inferencing.

Cheers,
Reto

Hi all,

Bastián (in CC) has created RDF Playground as a tool that we have been using to teach a course on the Web of Data. It has been very useful in this course and we think that some of you might also find it useful!


The system centres around an RDF graph (Turtle) with a graph visualisation, and allows for running SPARQL queries, RDFS/OWL 2 RL reasoning, SHACL and ShEx validation. The intent of the interface is to run small examples, useful for teaching or illustration purposes. In terms of the design, we wanted to show the different standards in a more integrated way (allowing to quickly switch between reasoning, querying and validation, on the same RDF graph, for example), while also putting emphasis on the graph-based nature of RDF through its visualisations (e.g., you can also view the results of reasoning, CONSTRUCT queries, etc., as an RDF graph). You can view a demo here:

        http://rdfplayground.dcc.uchile.cl/


At the bottom of the page you can load an example or play a video to demonstrate the features.


If you were thinking of using it in a course, it might be a good idea to
install it locally as the demo linked above is not a production system.
You can find the source code here:

        https://github.com/BastyZ/RDFPlayground


The system is implemented on top of Jena, ShExJava and RDFLib/OWL-RL
(with a Kotlin back-end to tie everything together). The front-end uses
Vue and node.js.

Indeed it might be great to set up mirrors if there were interest.



The system is most similar to (the very cool) RDFShape tool.

        https://rdfshape.weso.es/dataQuery


RDFShape offers many more features relating to ShEx/SHACL (and also
SPARQL), while RDF Playground integrates RDFS/OWL reasoning support and
a different interface style.


We have some plans to extend RDF Playground to integrate a Linked Data
browser (with the aim of connecting it more with the Web). Also there
are some minor "quality-of-life improvements" that could be added like
syntax highlighting, auto-completion, filters, etc.


We hope you might find RDF Playground useful!

Best,
Bastián & Aidan
