Visualize brick

[Macin Ma]

Hi, 

I am new to ontology domain but working on IOT project. I found concepts in Brick very interesting and I wanted to visualize brick schema ... yet I am unable to do so in viewer.brickschema.org ...

How do I do it? Take any of th URL here http://brickschema.org/schema/1.0.3/ and paste it in viewer.brickschema.org...

Nothing renders ...

 Am I doing something wrong?

What is recommended software for editing Brick schema? Tried protege but am unable to open it there ...

Thanks for help and all the best

Marcin

Hi Macin,

Thanks for reaching out us.

About viewer.birckschema.org: If you put one of the URLs in the page in the URL box, you would be able to see the visualization shortly. I just tested it with "http://brickschema.org/ttl/ghc_brick.ttl" and it worked.

About the editing: I just tested Protege and it worked for me. Which file did you download? This one should work: http://brickschema.org/schema/1.0.3/Brick.ttl It may warn that it can't import another ttl file, but you can just ignore it. 

Hope this helps.

With regards,

Jason Koh

Happened to shoot the email without answering the other remaining question about the best editor.

For GUI, I think Protege is the best one so far though it is not primarily designed for Brick. Once you get familiar with the concepts, it could be easier to edit the graph with Python scripts with rdflib (https://rdflib.readthedocs.io/en/stable/)

Here's a very basic tutorial: https://github.com/BuildSysUniformMetadata/brick-tutorial-buildsys2017/blob/master/1.%20Brick%20Composition.ipynb

We are dedicated to make Brick more usable and recognize that a canonical editor is much needed by the end users like you. We may bring a Brick-specialized editor in the future.

Thank you!

Thanks Jason,

Re: "We are dedicated to make Brick more usable and recognize that a canonical editor is much needed by the end users like you. We may bring a Brick-specialized editor in the future."

I could give you some insights of an complete beginner perspective...

1. I'm quite new to ontologies, but I understand their value in the IoT system we are building. Hence I've done some research and found brick - the idea of Location,Point, Equipment and relations proposed between those brought my attention

2. Now, what is next? I sens we should implement some kind of a mapper after the IoT edge which will translate data into Brick schema ... not sure how to approach this? My idea was to browse through the schema to see what's in there.

3. How to use brick schema for building digital twin? 

Those are the sort of main questions I have right now. I wish there was some tutorial on that. The difficult part is my team is not very keen on adopting ontology yet, so I am trying to find arguments and propose technical directions (being a business analyst) on how this should actually be incorporated.

If you could point me in some direction I would greatly appreciate.

All the best

Marcin

Hi Macin:

Thanks for reaching out!

There are a few next steps for Brick that I see. In no particular order:

1) expanding the set of equipment, things, etc that are described by Brick. Consumer devices, networking equipment, etc...

2) making it easier to create Brick models from other source data: Jason and I both have current efforts on this front and I believe some of it will be published soon. 

3) working on the "digital twin": it would be great to be able to use the Brick model to discover and interact with the environment. I have some work in that area (https://docs.xbos.io/) that's still under development, but there's certainly a lot of directions it could take.

Can you speak a bit more about your use cases? We are still actively developing Brick so there are not a lot of tutorials on it at this time
