Contains the mappings for linked ontologies. We use the Linked Places mappings found in http://linkedpasts.org/assets/linkedplaces-context-v1.jsonld
e.g. "@context": "https://raw.githubusercontent.com/LinkedPasts/linked-places/master/linkedplaces-context-v1.jsonld"
The type of each output is "FeatureCollection", according to GeoJSON-LD , containing one or more Feature objects.
Feature is a list, which can hold one or many feature objects. Each object can contain following elements:
This is a unique and permanent URI pointing to the entity in the OpenAtlas instance.
"@id": "http://thanados.openatlas.eu/entity/50505"
Show CIDOC CRM class code and name based on the Erlangen CRM
"crmClass": "crm:E18_Physical_Thing"
The value for type is "feature" to state, that the object is a feature.
The property element holds one key:value pair, because of the GeoJSON requirement. The key is title, which is the preferred name label of the entity. In the OA form it is called Form field name.
"properties":{
"title":"Gars Thunau Obere Holzwiese"
}
When is the temporally scope of the represented feature. OpenAtlas only supports dates in the YYYY-MM-DD format, so no periods or extensions for approximate and uncertain (for more details: Date).
Each "when" contains one timespans[] . A timespan can contain start{} and/or end{}. start{} or end{} hold timestamp values and the comments for the dates.

"timespans":[

"end":{
"earliest":"0950-01-01",

names is a list of Aliases.

Represents a list of one or more types objects (nodes) for this feature. Identifier refers to the type entity of the type and label is the given name of the type. Hierarchy lists the super types in a string for the THANATOS front end. If the type is a value type, the unit and value is also shown.

"hierarchy":"Evidence > Archaeology",

A GeoJSON FeatureCollection must have one or more geometry elements to be valid. Therefore each entity, even if it has no geometric references has this entry:
"geometry":{
"geometries":[ ],
"type":"GeometryCollection"
}
Type refers to geometric types according to RFC 7946 - The GeoJSON Format.
Geometries[] is a list of none or more geometric objects. Each of these objects have the following keys:
"geometry":{
"geometries":[
{
"coordinates":[
21.53314304247,
41.528480700127
