URI as result field

[david-batranu]

result_display formatting doesn't work and filters don't show when URIs are used as field names, for example, in the result below, "http://purl.org/dc/terms/creator" is used instead of "author", since currently the code assumes . is used to get data from an object, the split turns http://purl.org/dc/terms/creator into ["http://purl", "org/dc/terms/creator"] and breakes the functionality.

I forked the code and did a quick fix but my fix will not allow things like http://purl.org/dc/terms/creator.first_name to work, since it skips the split.

In the fix some jQuery selectors have been replaced with [id=""] syntax, as selectors like jQuery('#facetview_http_//purl_org/dc/terms/creator') don't seem to work using the standard syntax.

HI, yes the result_display method of displaying results is quite basic. For more complex displays - or as in this case for displays of data with complex keys, it would probably be better to use the post_search hook to get the result data into a custom js function that builds the result object onto the page in the desired way, and not bother using the result_display structure at all.

@markmacgillivray , thanks!
I just want to give some context on why we have URI as keys for anybody interested for semantic/RDF data indexing.

our overall architecture is as follow. we are using a RDF store (openlink virtuoso) as an integration server where we have data from many systems. Than we are creating a Semantic RDF River Plugin for Elasticsearch (https://github.com/eea/eea.elasticsearch.river.rdf) that can query SPARQL endpoints and index RDF data into ES. Than we are trying to use the okfn facetview to give a nice faceted search to the end-users.

This is already working nicely except from the fact that keys from a semantic point of view are URI so that we can distinguish between two fields with same representation but different meanings, e.g. http://xmlns.com/foaf/0.1/Person#name vs http://myownvocabulary.com/vocab/Chemical#name
one is the name for a person the other is a name for a chemical ... therefore URI containing the namespace (=ontology context) will differentiate these two field and we avoid clashes.

My aim as manager of this project at EEA is to contribute to this okfn product and avoid keeping a fork of it...so I really hope we can improve the original facetview to be more robust and flexible concerning the result data having more RDF alike values like URIs or json-ld style, making facetview displaying linked data a become a nice tool for building semantic web applications.

it would probably be better to use the post_search hook

If I'm not mistaking, the call of post_search is not properly implemented - the this object is the jQuery Ajax call object itself, it doesn't hold the response object or parsed search results.

options.post_search_callback.call(this);

this is jQuery.ajax() closure and can not be used to render results.

[markmacgillivray]

By the time the callback runs though, the query has executed and dumped the result data into the options. So you can write a callback that refers to the options of the facetview instantiated on the element, and get all the data you need from there.

Thanks, I didn't think that through :)
