enum Access

Module space

Access restrictions as characteristics of a space. This is used to identify what spaces in indoor maps are drivable, walkable, or both - or neither. This can be used e.g. by automated valet parking system to identify where a vehicle can drive. Vehicle-types cannot be used as it does not have a generic definition for vehicle, but ~20 separate ones, and if that class is extended by a new vehicle type, the drivable areas in existing indoor maps won't cover that new type. That is, the concepts are similar, and similarly named, but different. There is a well defined mapping, but indoor does not need, and is complicated by, the more precise granularity of the road network vehicle-types.

Space

feature Space extends MomFeature, VenueFeature

Module space

Space refers to a physical space in a building, e.g. a room

Property Type Modifier Description
momType "indoor.Space"
id string
bbox BoundingBox optional
geometry Geometry A space of type room is typically 'Polygon'

A spaceObject can be a point-object if we do not know its area from the raw material that the customer provides

- example ATM machine can be Point or Polygon.

Currently, walls and doors are also line-string/multi-line string, till we do not facilitate capturing of

the thickness (which generally no customer provide)
properties SpaceProperties Space-specific properties
referencePoint Point optional This is the location of this feature, collapsed to a single point.

This is for any application where an approximate, but deterministic and consistent, location is useful. One

example is deciding where to "anchor" a feature within a tiled map database.

Any Reference to this feature should include this point.
nonSpatialPartitionKey string optional The partition id for a generically partitioned feature.

Generically partitioned features fall into two categories:

1. Features that have a spatial component but may not make sense to partition based on that geometry.

2. Features that don't have a strong spatial component.

How keys will be assigned and what value ranges will be used are not specified.

Examples of generically partitioned features are admin, zone, postal, phonetics, metadata, etc.
Constraint Expression Description
atMostOneDefinedProperty (is-empty(.referencePoint) is-empty(.nonSpatialPartitionKey)) At most one of non-spatial-partition-key and reference-point can be defined.

SpaceProperties

part SpaceProperties extends Common, VenueFeatureProperties

Module space

Highest-level space properties

Property Type Modifier Description
@ns:com:here:mom:meta Metadata optional
@ns:com:here:mom:rmob string optional Currently not specified - may be specified by each Feature individually in future
featureType FeatureType optional Deprecated. This property is redundant to MomFeature.momType and should not be used.

MOM clients before 2.6 release had this deprecated property set to required, so

if data needs to be JSON schema validated by clients before 2.6 this property must be

set by the writer.
isoCountryCode Country optional Deprecated. This indicates which country a Feature is in, with a couple caveats.

- It may be unknown ("NONE" is a valid value, in addition to "UNDEFINED" like all MOM enums) simply because the

writer has not tried to figure it out or has otherwise not had the means to do so.

- It may be outright incorrect or a simplification of reality, specifically when a Feature is close to a country

border or in a disputed area (e.g., two or more countries claim the same area).

In all cases, writers and readers of this data should understand that the semantics of this property must be

agreed upon (if it is used at all). The preferred method of relating a Feature to a Country is through a

(direct or transitive) Reference from the Feature to an Admin.
@ns:com:here:mom:delta Branch optional
@ns:com:here:mom:mapcreator MapCreator optional
@ns:com:here:xyz Xyz optional Generic Data Hub namespace
extensionOSM MomOsm optional Optional extension for OSM (Open Street Map) metadata,

in case the object came from OSM
@ns:com:here:groundTruth GroundTruth optional Ground truth namespace
confidence ConfidenceData optional Confidence of a feature, optional only for the features

that are not participating in Quality Index.
venueId string optional Deprecated. Id of the venue. Venue Id is generated outside of MOM, and is used by the different components/services of venues.

There is no venue object, hence this is not a reference to any object,

but conceptually venue is a collection of objects of momType "indoor.{Site, Structure, Level, Space, Occupant}".

This id is linking every object to the venue.

It may have the same value as the Site object, but it doesn't have to have.

Each feature could be considered to be identifiable by a 2-level id: the venueId + feature id.

The feature id is also unique by itself.
indoorMapId string Id of the indoor map. The id is generated outside of MOM, and is used by the different components/services

of the indoor map.

Indoor map is a collection of objects of momType "indoor.{Site, Structure, Level, Space, Occupant, ...}".

This id is linking every object to the specific indoor map.

It may have the same value as the Site object, but it doesn't have to have.

Each feature could be considered to be identifiable by a 2-level id: the indoor map id + feature id.

The feature id is also unique by itself.
renderProperties RenderProperties optional optional object, will appear only for following objects Site, Structure, Level, Space (Vectors)
names Name list Name for spaceType is the name of the spaceType instance, e.g. a name of a conference room. SpaceType has

its generic name, e.g. "Conference Room".
spaceCategory string Space category helps to categorize the spaces in the UI, and e.g. do searches from data storage for a subset

of spaces

Possible values are available in MOM Types and Indoor Map Rules (external to MOM).
spaceType string Space type is the sub-type of space category; space categories have multiple space types with similar

characteristics.

Possible values are available in MOM Types and Indoor Map Rules (external to MOM).
spaceTypeProperties SpaceTypeProperties optional Attributes that client is expected to configure. Optional, as some space types don't have any configurable

attributes.
parentSpace Space optional Space marked as a logical parent, example a shelf for a bin.
spaceAddress Address optional Internal space address using indoor-micro-pa category in properties
level Level Level to which this space belongs to.
drawOrder integer Represents draw order of this Space/Geometry on the Level.

drawOrder is unique for all spaces of a given level.

It is an integer value >= 0.

It is used to construct the array of Features for a given level, the order is important for the SDK and

other Renderers.

It cannot be computed from stackIndex
stackIndex integer It represents how many spaces are beneath this space on the Level,

It cannot be computed from drawOrder.

Allowed value is an integer >= 0
customerReferenceId string optional Reference to customers MIS id with respect to this object, we are not obliged to manage it,

but will keep placeholder so that customer can edit value and use it with our products.
Constraint Expression Description
drawOrderMin0 (.drawOrder >= 0)
stackIndexMin0 (.stackIndex >= 0)

SpaceTypeProperties

part SpaceTypeProperties

This is a characteristics of the space type, not configurable
isNavigable boolean optional The space can be a destination of a navigation

This is a characteristics of the space type, not configurable
