Hi,
I need to configure a search service that looks up entities on a
ReferencedSite, but it should also retrieve property paths of length 2
for each entity found. But I would like to achieve it with a single
EntityHub call.
A use case example would be to have an autocomplete widget, where if you
type "wonderl" you get a result which displays "Alice in Wonderland" and
"author: Lewis Carroll" underneath.
Which implies a label/title search and then a path retrieval across,
say, dbpedia-ont:author and rdfs:label
Easy to do with SPARQL but I'd like to reproduce it with the EntityHub
query languages:
I've performed the first step using FieldQueries on the /query endpoint
very nicely so far, but for the second step (the label "Lewis Carroll")
I have to perform an additional query on /entity (or go LDPath if I
needed something more sophisticated).
It would be great to obtain these with a single query - not sure which
is the least expensive way to do so, though. Maybe I'm wrong assuming
LDPath does not handle a string search in its context?
Thanks for the help,
Alessandro
