Enrichment cannot create IRIs

[wouterbeek]

When we use a SPARQL query to enrich the ID in the following source table to an IRI:

BAG ID
123

We get the following linked data:

_:b0 <{baseIri}/BAG%20ID> "123" .
_:b0 <{baseIri}/BAG%20ID> "https://data.kkg.kadaster.nl/id/gebouw/123" .

But we expect:

_:b0 <{baseIri}/BAG%ID> <https://data.kkg.kadaster.nl/id/parcel/456> .

Currently, the built in Convert to IRI column refinement transformation will do this, it will replace the original value in the RDF file - not in the CSV file. A custom column refinement transformation will not do this, instead it will create a columnName-refined triple and and header in the CSV file.

Here is an example GIF of the current version of the repository, with a custom Column refinement that will add "-abc" at the end of the input value. I am using yarn dev for local development with the custom function set up in the "runtimeConfig.ts" file.

const wizardConfig = { appName: "LDWizard - example", defaultBaseIri: "https://w3id.org/my-wizard/", primaryColor: "#4caf50", // green secondaryColor: "#1565c0", // blue columnRefinements: [ { label: "Add -abc at the end", type: "single" as const, description: "This transformation will take input value and add '-abc' at the end", transformation: async (term: string) => { return `${term}-abc` }, }, ], }; export default globalThis.wizardConfig = wizardConfig

This has been resolved in version 3.0.0:

• by default LDWizard will return an URL that uses the default IRI (unless specified otherwise) with the csv value at the end, like it used to. This would look somewhat like this after the configuration step: https://data.pldn.nl/8f6052/def/{csv_value}
• within column refinements it can be specified if a transformation should return an IRI or literal with yieldsLiteral or yieldsIri.

Please feel free to reopen this issue if it persists.

Edit:

This behaviour changed in version 3.0.2:

• by default LDWizard will return a literal (this was request in #153). If an IRI output is desired with the base IRI, an empty transformation without specifying yieldsIri or yieldsLiteral should be used for this column - see this example in the runtimeConfig file.
