Extend EquipmentProperties to be suitable for ramp information

[k00ni]

I would like to add the following properties to EquipmentProperties in order to support more information about ramps.

Property	Type
rampLength	Length
rampWidth	Length
rampHeight	Length
rampAngle (rampGradient) ?	float
hasHandrailLeft	boolean
hasHandrailRight	boolean
rampStartAndEndColorized	boolean

I've chose the ramp suffix to be in line with properties like cabinLength and cabinWidth.

Using hasHandRail is not enough, because sometimes you only have a handrail on one side. For my case i would prefer information if there is one on each side, or not.

EDIT: Adapted the Type for ramp* properties.

The problem with 'left' and 'right' is that it's not really clear from where you look :) I'd rather keep it simple. For ramps, it's a bit more difficult: They can be different in different levels of elevators, for example, and I haven't seen data like this in the real world yet. Have you? I'd rather suggest to include this information in the way relations to the elevator, or have a Ramp entity to allow attaching multiple ramps to multiple elevator doors at some point.

Fair point.

[...] and I haven't seen data like this in the real world yet. Have you?

Yes. I am working with the Behindertenverband Leipzig e.V. since 2015 to release their database as Open Data, for instance. The database is maintained since 1997 and contains information about ~1800 buildings/places in Leipzig and their degree of accessibility. There are over 75 data fields, which describe relevant aspects of a place, for instance entrance, elevator, toilet and supports for visually and hearing impaired people.

In this database you will find exactly these information i was referring to. Its in German and called "Rampe-Handlauf-durchgehend-links-vorhanden" for instance, which translates roughly to "ramp-handrail-left-available".

Our working repository is https://github.com/AKSW/transform-bvl-pages-to-csv-file

You find an old version of the raw data here: https://github.com/AKSW/transform-bvl-pages-to-csv-file/blob/master/places.csv (here is an RDF version).

Thanks for this info! Then let's add these attributes and clarify in their documentation what 'left' and 'right' means.

Regarding "rampAngle"

I would use "rampGradient" instead, because it seems the best translation for "Steigung der Rampe" (source).

What measure/attribute is to use here? My data is currently modeled using percent, like 6%. @opyh I know we may discussed this yesterday, but i couldn't remember, if we came to a decision here.

What do you think?
