Opening local ontology directly from console about webvowl

[linkvt]

Hi,

nice to hear that everything works well so far.

Since WebVOWL is usually run on a webserver, loading files from a local system would not be possible, because it would be a cross origin request which is usually blocked by the browser.

You can make it work for you if you modify a single line of code.
If you change ontologyMenu.js#L89, from this
loadOntologyFromFile(filename);
to this
loadOntologyFromUri(filename, filename);
This will break uploading local ontologies via the web interface. If that's a problem, there is another workaround.
You also can't use this with Chrome without adding another launching parameter, but it seemed that you're only using Firefox.

In my case I could open a local json with a url similar to this: file:///C:/Users/.../WebVOWL/deploy/index.html#file=file:///C:/Users/.../WebVOWL/deploy/data/foaf.json

Hi,
Sorry for not writing sooner. I was working on something else.
I changed the code as shown and tried it. If I try to load any local files now, I'm getting these errors:

(browser console): NS_ERROR_DOM_BAD_URI: Access to restricted URI denied

(linux terminal): 1462200191024 addons.productaddons WARN Failed downloading XML, status: 0, reason: error

And WebVOWL is stuck in loading mode forever.
Any kind of help is appreciated.

Can you comment the URL you used?

[DrDizzle]

firefox file:///var/tmp/WebVOWL-git/deploy/index.html#file=file:///home/os/Desktop/net2vowl/test/oEKb.141.json

This is the exact call I used, but the loading problem also occurres when I'm trying to load a file the regular way:
Ontology -> Select ontology file -> 'Selecting file' -> Upload

Hmm, did you adjust the code exactly as described above? As I mentioned there, this would break uploading ontologies from a local file.

You could test it with the attached version: webvowl-master-898fdfb.zip

Uploading your ontology from a local file on the hosted WebVOWL does work, doesn't it? Because otherwise it might be a corrupt json.

[DrDizzle]

Yes, I did it exactly as you described it. The version you posted throws exactly the same error as my version.
When I upload my file to the hosted WebVOWL or build the newest version without changes, I can load the file the regular way, through the ontology menu. So the file seems to be valid.
I also found a different error. I don't know if I overlooked it or if it's new.

TypeError: S is undefined
u() webvowl.js:2
t() d3.min.js:1
oa.layout.force/l.tick() d3.min.js:4
Rn() d3.min.js:1
Tn() d3.min.js:1

I would guess this is the main problem.

[linkvt]

Hmm thats strange. Could you attach the json file you used?
I can't do that much just from your error description, since it's working for me. This would help a lot and let me debug the error you received.

For some reason the upload isn't working. So, I've got to do it the old fashioned way:

I just found out, that the file has to be in the same directory or a subdirectory of the folder where the index.html is placed, or otherwise the browser will block the request, see more here: Same-origin_policy
You might have to configure your browser to allow these requests, I guess there are some ressources on the internet.

I just visualized your json with and exported the SVG file: exported-graph.zip
I noticed you're using an old version of OWL2VOWL (but the latest available I think) - there will soon be a new release for OWL2VOWL with many improvements.

It's finally working. Thank you.
Just using a subdirectory was the best solution for me. I'm not very familiar with CORS and it doesn't really matter where I store my data.
