CSO data compatibility

[arekstasiewicz]

I was trying to use CubiQL with CSO endpoint:

java -jar graphql-qb-0.2.1-SNAPSHOT-standalone.jar --port 9000 --endpoint http://data.cso.ie/sparql

The following error is displayed:

@zeginis Could you please advise how complicated it would be to make the data work with the API?

[zeginis]

@arekstasiewicz there requirements for data to work with CubiQL are documented at: #92.

Most of these will be fixed. There are 2 open issues:

• Always use the qb:measureType even if there is only one measure. We need to discuss this.
• A qb:codeList should be defined for each dimension of the cube that contains only the values used in the cube. Most probably we will adopt this approach.

As a first step you can add (qb:codeList) the codelist that are defined at CSO to the dimensions. I have checked them and all the values they contain are used at every cube, so they are compliant with the above requirement (The only exception is the age dimension)

Hi @zeginis I am attaching a sample cube I created to align with CubiQL cso_noENtag.ttl, but still throwing error at creation time. I have addressed the following data restriction issues: 1- qb:codeList 2- qb:measureType 3- Language tag 4- multiple publishers

what is it still missing? error: exception in thread "main" clojure.lang.ExceptionInfo: Call to #'com.walmartlabs.lacinia.schema/compile did not conform to spec: In: [0 :objects :dataset_cso 1

#grafter.rdf.protocols.LangString{:string "CSO", :lang :en}

@mohadelrezk this line says that there is an en language tag at the label "CSO". I checked at the data but the "CSO" label does not have a language tag. Are you using just the file you send as input or something more?

The qb:codeList of the cube dimensions should be a skos:ConceptScheme that includes all the URIs that are used as values of the dimension. At the file you send I see you use: qb:codeList "<http://purl.org/linked-data/sdmx/2009/subject#>"

Additionaly it is preferable to use URIs instead of string for the values of the dimensions e.g. use http://reference.data.gov.uk/id/year/2016 instead of "2016"^^xsd:string
