Histograph Schemas

Creates JSON schemas and Turtle/N3 ontology from types and relations in Histograph configuration file.

var schemas = require('histograph-schemas');

// schemas.pits:         PITs JSON schema
// schemas.relations:    relations JSON schema
// schemas.dataset:      dataset JSON schema
// schemas.graphmalizer: [Graphmalizer](https://github.com/graphmalizer/graphmalizer-core) configuration

schemas.ontology(function(err, results) {
  // results:            Turtle/N3 ontology
});

PITs

All PITs must have either an id or an uri and a type, and optionally geometry, data and date fields. Hence, a line in a NDJSON file containing PITs can be either:

{"id": 123, "type": "hg:Place"}

Or:

{"uri": "http://sws.geonames.org/2331234", "type": "Place"}

Relations

All relations must have from, to and type fields:

{"from": "http://sws.geonames.org/2331234", "to": "gemeentegeschiedenis/leiden", "type": "liesIn"}
