Hi there,
I noticed that the GEMET client (listed at bottom of http://svn.eionet.europa.eu/[…]/GEMETWebServiceAPI) is no longer functioning. It appears that eionet content has moved and the links in GemetClient.js therefore need updating. I'd be grateful for any suggestions on how to resolve. Thanks, Richard.

Start of GemetClient.js file:
var ThesaurusReader=function(config){this.INSPIRE="http://inspire.jrc.it/[…]/";this.appPath="";if(config.appPath){this.appPath=config.appPath;}
this.url="http://www.eionet.europa.eu/gemet/

kind regards

The GEMET API used to have a bug in its JSON output. The bug was fixed, but the PHP script in the example is failing for some reason. You could try to contact the maintainers of that client.

Nope, the bug is still there but it is limited to method getRelatedConcepts
After trying this call:
http://www.eionet.europa.eu[…]%23narrower&language=pl
you will get following results:
["{\"preferredLabel\": {\"string\": \"model\", \"language\": \"pl\"}, \"definition\": {\"string\": \"1) przedstawienie, zwykle w mniejszej skali, okre\\u015blonego urz\\u0105dzenia, budowli itp.; 2) ilo\\u015bciowe lub matematyczne przedstawienie lub symulacja komputerowa, kt\\u00f3ra ma celu opis w\\u0142a\\u015bciwo\\u015bci lub zale\\u017cno\\u015bci pomi\\u0119dzy zdarzeniami fizycznymi\", \"language\": \"pl\"}, .....
but valid result should looks like that:
[{"preferredLabel": {"string": "model", "language": "pl"}, "definition": {"string": "1) przedstawienie, zwykle w mniejszej skali, okre\u015blonego urz\u0105dzenia, budowli itp.; 2) ilo\u015bciowe lub matematyczne przedstawienie lub symulacja komputerowa, kt\u00f3ra ma celu opis w\u0142a\\015bciwo\u015bci lub zale\u017cno\u015bci pomi\u0119dzy zdarzeniami fizycznymi", "language": "pl"}, .....

Yes, that is correct - there was a faulty double json serialization.
getRelatedConcepts call works now as expected.

Thanks very much for following up. I'm still keen to use the GEMET client, and would be very grateful if you could kindly share the details of the fix I need to resolve the GEMET bug - which file(s) and code would I need to amend? I did try contacting the developer but haven't received a reply as yet. Thanks again, Richard.

I'm not an expert in Javascript, but according to docs at https://svn.eionet.europa.eu/[…]/GEMETWebServiceAPI there are now following thesauri uris:
1 http://www.eionet.europa.eu/gemet/concept/ Concepts
2 http://www.eionet.europa.eu/gemet/supergroup/ Super groups
3 http://www.eionet.europa.eu/gemet/group/ Groups
4 http://www.eionet.europa.eu/gemet/theme/ Themes
5 http://inspire-registry.jrc.ec.europa.eu/[…]/ Inspire themes

Looking at the code of thesaur.js of the GemetClient I've found the following line:
    /* Initial config values */
    this.INSPIRE = "http://inspire.jrc.it/theme/";
    this.CONCEPT = "http://www.eionet.europa.eu/gemet/concept/";
    this.GROUP = "http://www.eionet.europa.eu/gemet/group/";
    this.SUPERGROUP = "http://www.eionet.europa.eu/gemet/supergroup/";
    this.THEME = "http://www.eionet.europa.eu/gemet/theme/";

The only one uri that doesn't match is INSPIRE themes thesauri, so I suppose that changing:
this.INSPIRE = "http://inspire.jrc.it/theme/";
to
this.INSPIRE = "http://inspire-registry.jrc.ec.europa.eu/[…]/";
will be enough to fix your problems.

This is a bug at GemetClient and you should consider sending ticket to GemetClient developers.

You may also try my own implementation in metadata editor Medard at http://http://medard-opensource.eu/en.

Hi, I was trying out the modified GEMET client, and was getting a "Data error" response on clicking the green arrow icon.

I checked out GEMET client from as
svn co https://svn.eionet.europa.eu/[…]/
It is revision 27940.

I tested using the index.html page in the /src directory. Are there any additional configuration issues I may need to consider?

Cheers,
Richard

Hi Richard,

Yes, I thought I documented this in the Readme last time we refactored the client, but it seems I missed it - there is a php script used for the Ajax calls - because you can not make cross-domain requests from client side; you need to have it configured and set the working path to it in the index.html from /src, line 48.

Anyway, we just implemented some months ago the Jsonp support in the Gemet Web Service, so there is no need for this serverside script. We shall update the GemetClient to use json with padding requests (ext-js provides Ext.data.ScriptTagProxy for this purpose) and get rid of the PHP requirement.
simiamih Jul 12, 2012 10:24 AM
Sorry for the big delay. You can now checkout the latest version which works out of the box, without server side requirements - please let me know how it goes.
PS: It might not work if it isn't used on a domain, it makes HTTP requests which need to be signed with an originating domain.

Hi,

Thanks for your help.

To confirm, I now have the GEMET application working online.

I've now integrated into the EPDI main website (enviroprojects.org) and EPDI Website Template (enviroprojects.org/epditemplate). Also posted as a blog entry at http://enviroprojects.org/b[…]supported-by-epdi-websites.

Thanks,
Richard
