hello I am studying about semantic web with eye.

If I access eye server with data.n3 & query.n3 in cloud
URL : http://localhost:8000/?data=http://104.199.143.230:8080/data.n3&query=http://104.199.143.230:8080/query.n3

I can gain result.

PREFIX log: <http://www.w3.org/2000/10/swap/log#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>

:hello2 rdfs:subClassOf :helloAPM.
:hello rdfs:subClassOf :helloAPM.
:hello3 rdfs:subClassOf :helloAPM.

But if I access with data.n3(same as cloud file) in local file:///Users/kimmyongjoon/NetBeansProjects/tourAPI/data/data.n3
URL : http://localhost:8000/?data=file:///Users/kimmyongjoon/NetBeansProjects/tourAPI/data/data.n3&query=http://104.199.143.230:8080/query.n3

I can not result : result looks like can not read local file

How can I access with local file ?? or i need to upload it to cloud?

Issue:

$ docker run --name=eye_server -p 8000:8000 bdevloed/eyeserverERROR: Could not start EyeServer
Possibly the eye command could not be found, or /tmp has no write permission.

Error detail:
 gre ** error(process_error(/usr/local/bin/carl,exit(255)),_4250)

Cause:
Since EYE v18.0131.1211 carl is mandatory

Carl follows Turtle and SPARQL instead of the n3 team submission on several points. This includes no longer defaulting the empty prefix to the local namespace of the file.

This leads to an error at initialization, where the test data contains empty prefixes without a prefix declaration.

I'll send a pull request to fix this

BLUF: it appears the eyeserver can not spawn eye and there is only the /opt/eye/bin/eye.sh and no eye executable that I can find (there is the /opt/eye/lib/eye.pvm though)

I have followed the installation instructions here:
http://eulersharp.sourceforge.net/README.MacOSX
to install eye correctly (see version displayed below for eye, swipl, carl, cturtle, node, and npm)
but when I run: eyeserver 8000 I get this error:

I am running XQuartz.app v2.7.11 and logged out/in before attempting to run the eyeserver.

Running as sudo doesn't have any effect to resolve the problem.

Hi
I downloaded eveserver through a npm.
eye command works, but eyeserver 8000 make error.

I considered #10 but could not find the problem.
How can I solve the error?

What do you think about moving eye.js to separate repo/library? I made something similar for one of my projects, but it would be nice to have a single one that can be easily reused.

Hola!

I am sure it is something really simple I am missing. I want to use the api but cannot get it to work as designed with local web server files (port 80). Here are some images that depict what I am experiencing. I'm on an M1 Mac Mini (Monterey) if that makes any difference.

First, I try the sample post provided on the github repo home page in postman (which works!):

Then I create a local web server (on port 80), files are accessible by a browser without specifying port:

Then I try the same post, except this time I point to the files on the local web server:

Then I tried the same post in a Notebook in Visual Studio with Python requests object:

Lastly, (what did work!!!) I gave the eye CLI the same arguments (local web server addresses) to the files and it worked!!

Any guidance on how to get this working as intended would be greatly appreciated!

Thanks!

Hi,

I'm getting the following error when I try to run EyeServer with 'eye server 8000' on Mac.

Thanks.

Working on RDF visualisation from several years, i'd like to put a reasoner in my javascript webapps, so I've tried the command from my Linux as mentioned in the README.md like this :

curl "http://eye.restdesc.org/?data=http://eulersharp.sourceforge.net/2003/03swap/socrates.n3&query=http://eulersharp.sourceforge.net/2003/03swap/socratesF.n3"

The result is :

PREFIX : <http://www.agfa.com/w3c/euler/socrates#>

:Socrates a _:e_Man_1.
:Socrates a :Mortal.

Could you explain me what is the "_:e_Man_1"
thxs

I couldn't find the license. Pleas add one.

Hi Ruben,
When I stress EyeServer using the following script, there is some errors (some empty results). Any idea?
Thanks,
Olivier

I trying to use eyeserver with window

eye command works, but eyeserver 8000 make error.

How can I avoid this error?

A while ago, I splitted off the eye wrapper to modernize it and use it in some other project: https://github.com/mielvds/EyeJs
Back then, the logical follow-up was to create a PR that would remove this logic and import the EyeJs package (not sure that's the best name either), but I never got to it.

I'm opening this issue to not forget about it and also to check whether this is actually desired.

I am trying to use eyeserver in window 9 OS.

After install curl,cturtle,swipl,eye and command well in cmd, but eyeserver 8000 command make error.

I will find why this error evoke.

Hi Ruben,

I am starting to use EyeServer today. Quite excited :). Just a minor remark upfront, I was somehow (don't know why, really) expecting the module to handle the installation of eye. Although I fully understand it is better to have it as a requirement, it could be useful to indicate this in the README as I spent quite some time realising that was my issue...

In case it can help anyone go faster, here is a small script to install the latest (to date) version of EYE.

#!/bin/bash                                                                                                                        
cd ~/
wget http://sourceforge.net/projects/eulersharp/files/eulersharp/EYE-2014-09/eye.zip
unzip eye.zip -d eye
sudo add-apt-repository -y ppa:swi-prolog/stable
sudo apt-get update
sudo apt-get install -y swi-prolog
cd eye
sudo ./install.sh
sudo ln -s /opt/eye/bin/eye.sh /usr/bin/eye
cd ..
rm -rf eye/
rm eye.zip
echo "Should print EYE version below..."
eye --version

I want to use EyeServer from my webApp https://spoggy0.firebaseapp.com/ ( clic the "cat" icon to toggle to the chat/graph page, then clic on "..." icon to open "Eye reasoner" panel)

Then clicking on "Execute Eye" , the app send this data :

data=@prefix : <ppl#>.
 
:Spoggy :type :WebApp.
:Spoggy :developpeur :David.
:David :connait :Bob.
:Spoggy :hasPart :Graph.

&data=@prefix : <ppl#>.
         { ?a :connait ?b }
 =>
         { ?b :connait ?a .
           ?a :type :Personne.
           ?b :type :Personne}.

          {?c :developpeur ?d}
          =>
          {?d :type :Developpeur}.

          &query={ ?a ?b ?c. } => { ?a ?b ?c. }.

to the eye endpoint : http://eye.restdesc.org/

but i got this error message :

iron-request.html:331 Mixed Content: The page at 'https://spoggy0.firebaseapp.com/' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://eye.restdesc.org/'. This request has been blocked; the content must be served over HTTPS.

It seems that the problem could be resolve, if the endpoint server could provide "https" instead that "http" as describe here https://developer.mozilla.org/en-US/docs/Web/Security/Mixed_content/How_to_fix_website_with_mixed_content.

Could you migrate to https or do I have to find another solution. ?
NB :
(my code works correctly on localhost)
(don't be afraid with the error : "GET https://spoggy0.firebaseapp.com/socket.io/?EIO=3&transport=polling&t=L-TLMwH 404 ()" , this is another problem (firebase don't accept socket.io ;-\ )
