Advanced tools
Tools for working with the JSKOS data format.
This repository contains tools for working with the JSKOS data format for knowledge organization systems.
npm i jskos-tools
const jskos = require("jskos-tools")
let concept = {
...
}
jskos.validate.concept(concept) // returns true or false
// or jskos.validate.scheme(scheme)
// or jskos.validate.mapping(mapping)
// ...
Directory bin also contains a command line script for validation.
Returns the version of the JSKOS specification that's used for validation.
jskos.version // 0.4.2
let mapping = {
...
}
mappingContentIdentifier starts with urn:jskos:mapping:content: and takes concepts and type into consideration. It uses the mappingContent function to get relevant properties from the mapping.
let contentIdentifier = jskos.mappingContentIdentifier(mapping)
mappingMembersIdentifier starts with urn:jskos:mapping:members: and only takes concepts into consideration. It uses the mappingMembers function to get relevant properties from the mapping.
let membersIdentifier = jskos.mappingMembersIdentifier(mapping)
addMappingIdentifiers creates a new mapping with property "identifiers", containing mappingContentIdentifier and mappingMembersIdentifier.
let mappingWithIdentifiers = jskos.addMappingIdentifiers(mapping)
compareMappings compares two mappings based on their mappingContentIdentifier.
if (jskos.compareMappings(mapping1, mapping2)) { ... }
Aliases: compareMappingContent
compareMappingMembers compares two mappings based on their mappingMembersIdentifier.
if (jskos.compareMappingMembers(mapping1, mapping2)) { ... }
Add @context URI to a JSKOS object or to an array of JSKOS objects.
jskos.addContext(object)
Removes properties starting with _ or containing only uppercase letters from a JSKOS object.
jskos.clean(object)
Aliases: cleanJSKOS
Creates a deep copy of a JSKOS object, replacing possibly circular structures with open world [null] statements.
jskos.copyDeep(object)
Aliases: deepCopy
Returns all possible URIs for a JSKOS object. Takes into consideration both the uri and identifier properties, as well as different variants of those identifiers.
jskos.getAllUris(object)
Compares two objects based on their URIs, using getAllUris.
jskos.compare(object1, object2)
Aliases: compareObjects, compareSchemes, compareConcepts
Checks whether JSKOS object is a concept based on type property.
jskos.isConcept(object)
Checks whether JSKOS object is a concept scheme based on type property.
jskos.isScheme(object)
// Checks whether an object is contained in a list of objects using compare.
jskos.isContainedIn(object, listOfObjects)
Aliases: isSchemeInList
Sorts a list of concepts by their notation, then URI. Returns a copy of the list.
jskos.sortConcepts(concepts)
Sorts a list of schemes by their German prefLabel, then URI. Returns a copy of the list.
jskos.sortSchemes(schemes)
Removes unnecessary properties from mapping before export or saving. In particular, all properties except for to, from, toScheme, fromScheme, type, and creator on the mapping will be removed, and all properties except for uri and notation on concepts and schemes will be removed.
let newMapping = jskos.minifyMapping(mapping)
An array of mapping types in form of objects. Objects can have the following properties:
notation - an array of notations (in this case symbols)uri - the URI of the mapping typeprefLabel - a language maps of labelsbroader - array of broader mapping types for this typerelated - array of related mapping typesRELEVANCE - relevance label for GND terms (low, medium, high, very high)short - a short name for the type, used for CSV import/exportExample object:
{
"notation": ["≈"],
"uri": "http://www.w3.org/2004/02/skos/core#closeMatch",
"prefLabel": { "en": "close match" },
"broader": [ { "uri": "http://www.w3.org/2004/02/skos/core#mappingRelation" } ],
"RELEVANCE": "high",
"short": "close"
}
Returns a mapping type object for an URI.
jskos.mappingTypeByUri("http://www.w3.org/2004/02/skos/core#closeMatch")
Returns a mapping type for a JSKOS type property. This is usually an array where the first type is taken, but a workaround for string types is included as well.
jskos.mappingTypeByType(mapping.type)
The default mapping type (currently mapping relation).
Returns a configured converter from JSKOS mapping to CSV line. By now only simple 1-to-1 mappings and 1-to-0 mappings are supported.
let mappingToCsv = jskos.mappingToCSV({ delimiter: ';' })
mappingToCsv(mapping)
Concept labels are included only if configuration field language is set. The order of CSV fields is fromNotation, (fromLabel,) toNotation, (toLabel,) mappingType.
