UI proof of concept

[ddeboer]

Use case: Colonial Heritage.

• Select two dataset summaries. @ddeboer
  • NMVW / JSON-LD
  • Bronbeek
• Convert the summaries (JSON-LD.zip) to readable/framed JSON-LD to provide to Stefan. @pmaria
• Create a visually appealing detail page for each.
• Come up with a simple search/compare interface for the two datasets.

I framed the results using the following frame:

{
  "@context": {
    "nde": "https://www.netwerkdigitaalerfgoed.nl/def#",
    "prov": "http://www.w3.org/ns/prov#",
    "schema": "https://schema.org/",
    "void": "http://rdfs.org/ns/void#",
    "xsd": "http://www.w3.org/2001/XMLSchema#",
    "classPartition": "void:classPartition",
    "class": { "@id": "void:class", "@type": "@id"},
    "entities": { "@id": "void:entities", "@type": "xsd:integer" },
    "propertyPartition": "void:propertyPartition",
    "distinctValues":  { "@id": "void:distinctObjects", "@type": "xsd:integer" },
    "property": { "@id": "void:property", "@type": "@id"},
    "dataDump": "void:dataDump",
    "distinctSubjects":  { "@id": "void:distinctSubjects", "@type": "xsd:integer" },

    "sparqlEndpoint": { "@id": "void:sparqlEndpoint", "@type": "@id"},

    "vocabularies": { "@id": "void:vocabulary", "@type": "@id", "@container": "@set"},
    
    "wasGeneratedBy": "prov:wasGeneratedBy",
    "Activity": "prov:Activity",
    "startedAtTime": { "@id": "prov:startedAtTime", "@type": "xsd:dateTime" },
    "endedAtTime": { "@id": "prov:endedAtTime", "@type": "xsd:dateTime" },

    "type": "@type",

  },

}

Here are the results: JSON-LD-Framed.zip

@ddeboer could you review?

[ddeboer]

Thanks @pmaria, looks good to me!

What strikes me looking at the JSON-LD is that having separate blank nodes for the same class partition looks overly verbose:

  "classPartition": [
    {
      "class": "https://w3id.org/pnv#PersonName",
      "entities": "189063"
    },
    {
      "class": "https://w3id.org/pnv#PersonName",
      "propertyPartition": {
        "distinctValues": "72130",
        "entities": "189057",
        "property": "https://w3id.org/pnv#baseSurname"
      }
    },
    {
      "class": "https://w3id.org/pnv#PersonName",
      "propertyPartition": {
        "distinctValues": "54198",
        "entities": "184846",
        "property": "https://w3id.org/pnv#firstName"
      }
    },
    {
      "class": "https://w3id.org/pnv#PersonName",
      "propertyPartition": {
        "distinctValues": "188920",
        "entities": "189063",
        "property": "http://www.w3.org/2000/01/rdf-schema#label"
      }
    },
    {
      "class": "https://w3id.org/pnv#PersonName",
      "propertyPartition": {
        "distinctValues": "341",
        "entities": "34366",
        "property": "https://w3id.org/pnv#infix"
      }
    },

Should we merge those into a single class partition with multiple property partitions?

Of course, this is something that should happen inside the pipeline rather than the conversion to JSON-LD. I’m not sure yet what would be the best way to reference blank nodes between isolated analysers. Should we coin URIs for the analyser output instead?

[pmaria]

@ddeboer yes agreed. We could indeed use some repeatable URI generation to group the property partitions under the same class partition.

Done in #66.
