REST API - Get all enrichments based on entity x

[jthomsen]

GET /entity/{uuid}/enrichment

Q: is this possible? Does the model support annotations attached entities?

[jthomsen]

SPARQL query:

PREFIX linkedtv: <http://data.linkedtv.eu/ontologies/core#>
PREFIX ma: <http://www.w3.org/ns/ma-ont#>
PREFIX oa: <http://www.w3.org/ns/oa#>
PREFIX prov: <http://www.w3.org/ns/prov#>
SELECT DISTINCT ?item
WHERE {
  ?mediaFragment ma:isFragmentOf ?mediaResource . 
  ?mediaFragment a ma:MediaFragment . 
  ?annotationEntity oa:hasTarget ?mediafragment . 
  ?annotationEntity oa:hasBody ?entity . 
  ?entity a linkedtv:Entity . 
  ?annotationRelResource a oa:Annotation . 
  ?annotationRelResource prov:wasDerivedFrom ?entity . 
  ?annotationRelResource oa:hasBody ?item . 
}

has been realized with the above SPARQL query; sample call

This triple pattern (?mediafragment linkedtv:hasSubtitle ?subtitle ) seems useless.
The triple pattern (?item ma:locator ?url) is useful only if you add ?url in the select clause.
More generally, avoid to put any additional triple patterns that are useless, this is a sub-optimization for the SPARQL endpoint that needs to perform unnecessary check.

[jthomsen]

yeah, thanks again (actually I took the (?mediafragment linkedtv:hasSubtitle ?subtitle ) pattern from an example in D2.4 ;-) - was indeed not sure if it's really needed ...

[rtroncy]

It's not ... since you don't use ?subtitle later on
