Modelling a movable bridge as Building

We are trying to model a movable bridge using the smart data model classes.

In our current approach we want to link a Building of category = 'bridge' with a RoadSegment with its properties status and statusDescription to model the dynamic character of the bridge (i.e., it can be opened or closed). The following figure illustrates our approach:

In this vein, we would like to propose an extension of the Building model with a passedBy (alternatively, refRoadSegment?) attribute. If there are no objections, we will prepare a pull request with the corresponding change.

Thank you!

Inconsistency Relationship vs Property

The schema for Building has a field occupier, which is described as an array of relationships.

dataModel.Building/Building/schema.json

Lines 99 to 113 in d3b68e7

	"occupier": {
	"type": "array",
	"description": "Relationship. Person or entity using the building. Model:'https://schema.org/URL'",
	"items": {
	"oneOf": [
	{
	"type": "string",
	"format": "uri"
	},
	{
	"$ref": "https://smart-data-models.github.io/data-models/common-schema.json#/definitions/EntityIdentifierType"
	}
	]
	}
	},

But in the example building the attribute occupier is a Property, not a Relationship.

dataModel.Building/Building/examples/example-normalized.jsonld

Lines 107 to 112 in d3b68e7

	"occupier": {
	"type": "Property",
	"value": [
	"urn:ngsi-ld:Person:9830f692-7677-11e6-838b-4f9fb3dc5a4f"
	]
	},

I am trying to understand if this is i) a mistake, ii) a shortcoming of the spec, which does not support multiple relationship or iii) something else

When sending data with this data model to QuantumLeap, persisting data to Timescale fails.

"occupier": [
    "9830f692-7677-11e6-838b-4f9fb3dc5a4f"
  ],

is causing problems. QL issue for reference.

Do NGSI-LD examples include the correct context file?

When I autogenerate a context file using https://fiware.github.io/tutorials.NGSI-LD/models/building.yaml#/Building in the generated context file I am getting attibutes such as

"addressCountry": "schema:addressCountry",
"addressLocality": "schema:addressLocality",

These attriburtes are not included in https://raw.githubusercontent.com/smart-data-models/dataModel.Building/master/context.jsonld which is the context file of the examples
