The SPARQL query is missing the following mandatory variables

sparqlunicorn-0.13.1

Query > Configure TripleStores > Choos Triple Store "Nomisma" (or any other store):

The SPARQL query is missing the following mandatory variables:

"" (empty)

In addition (maybe as a follow up error) no changes can be made to the configuration nor a new tripel store can be created. The roor message is:

Thank you for your bug report!

Yes, the configuration dialog is partly unfinished, due to the implementation of the autodetection feature. The idea would be that minimal configuration is necessary for a triple store. I am also thinking about removing the dialog or massively simplifying it because the configuration options are getting quite numerous (not all configuration settings are in the configuration dialog anyway) and most users will not be familiar with all the configuration settings anyway. Any suggestions welcome here!

I suggest you try the autodetection (usually this is sufficient to include your triple store) If you have special configuration needs, just send us an email and we can look into your case. The manual way would be to edit the JSON file in QGIS_PLUGIN_PATH/conf/triplestoreconf.json We can provide you a JSON snippet for your configuration if needed.

Thanks for your quick response.

I think you mean by "autodetection" the button "Detect Configuration". So that the user just enteres a URL in the field "Triple Store URL", like "http://nomisma.org/query". But whenever I try the "Detect Configuration" I do get the same error message as the above:

So I do not have the experience yet to build my own suggestion for the needed/desired configurations via the UI yet. Anyhow: I think that the modification via the conf file should be doable. It looks like that the current implementation copies the triplestoredialog.py to triplestoreconf_personal.json. A modification in one of these files is not recognized by the plugin. That means that for any modification of the file a restart of the QGIS is required. If a conf file is the way to go than it would help a lot to reread the conf automatically once its got modified.

Some observations from my side:

• Nomisma works in the plugin, as it is already autoconfigured and therefore in the triple store menu
• The plugin will expect that SPARQL queries include a variable ?item and either a variable ?geo for a geoliteral or variables ?lat ?long for coordinates, maybe these were missing in your queries?
• I did not mean the "Detect Configuration Button" but the "Quick Add Endpoint" Button in the main window. That should work and is the recommended way to include triple stores even without modifying the configuration file. I tried to include nomisma there and this also seems to work
• The dialogue you are using as I mentioned before seems out of date and I can reproduce the errors you mention within the dialogue. I will add a fix for this, but we will as I said consider either massively simplifying or removing it anyway

In a nutshell: You should be fine with the "Quick Add Endpoint" Dialogue in most cases

[Msch0150]

I checked "Quick Add Endpoint". Looks quite sufficient.

Version 0.14 improved the Quick Add Dialog and the configuration dialog to solve these problems. Closing this one
