Major changes in 5.0 release are described here: https://github.com/AKSW/transform-bvl-pages-to-csv-file/releases/tag/5.0-alpha

Changes since alpha2:

• ID generation is not random anymore
• for door type (entrance) and vanity basin fitting activation (toilet) the value is string instead of an URI from now on
• added new properties (contact details about the place; contact person)

Changes

• elevators can only be partly accessible, not fully, because source data is not complete. whats missing is the information about the turning radius before the elevator for instance.

Additions

• added p:elevatorSuitableForWheelchairs to outline if an entry is suitable for wheelchairs. user doesn’t have to check related properties by himself anymore.
• mark all entries in the RDF file as publicly-available (relevant for building-navigator use case) - see https://github.com/AKSW/building-navigator/issues/49

Why a new major already?

We changed the data model of the RDF file again, therefore a new release.

Major changes

Change the meaning of values

• teilweise/vollständig became partly/fully
• ja/nein became true/false

These 2 changes allow a better data interoperability, because the usage of English terms. Even people who don’t know the German language, can use our data (at least partly).

Changed properties

• suitableForWheelchairs => entranceSuitableForWheelchairs, elevatorSuitableForWheelchairs, toiletSuitableForWheelchairs
• locationOfTheBell => entranceLocationOfTheBell
• bellWithIntercomAvailable => entranceBellWithIntercomAvailable
• bellHeightOfHeighestButtonCm => entranceBellHeightOfHeighestButtonCm
• continuousHandrailLeftAvailable => entranceContinuousHandrailLeftAvailable
• continuousHandrailRightAvailable => entranceContinuousHandrailRightAvailable
• doorType => entranceDoorType
• rampAvailable => entranceRampAvailable
• rampLengthCm => entranceRampLengthCm
• rampHeightCm => entranceRampHeightCm
• rampWidthCm => entranceRampWidthCm
• rampContinuousHandrailLeftAvailable =>
  entranceRampContinuousHandrailLeftAvailable
• rampContinuousHandrailRightAvailable =>
  entranceRampContinuousHandrailRightAvailable
• rampStartEndColorized => entranceRampStartEndColorized
• turningCircle => elevatorTurningCircleExit
• emergencyBellInsideCabinAvailable => emergencyBellInsideToiletCabinAvailable
• distanceFromGroundEmergencyBellInsideCabin =>
  distanceFromGroundEmergencyBellInsideToiletCabin
• supportHandleAvailable => toiletSupportHandleAvailable
• vanityBasinFittingActivation => toiletVanityBasinFittingActivation

Simplified RDF mapping (R2RML)

At first, we used a mapping which used a place resource with resources for major elements, such as toilet or entrance. After a few tests it felt like an overkill, because the people who have to maintain the RDF data later on, are not trained in data or knowledge management. Therefore a reduction to a star-scheme, which means that there is only a place resource hold all information about a place.

Also:

• merged Location and Address information
• renamed le-online-extracted-places.csv to places.csv

Updated data

Provided csv and n3 dump contains latest data from the Behindertenverband Leipzig.

Highlights:

• Fixes in R2RML-mapping (fixed errors, added a few mappings for missed properties)
• refinements in README.md

Highlights

• R2RML mapping to fuel tools which can transform a CSV file to a RDF file, such as sparqlmap
• added RDF version of the enriced CSV file (places.ttl)
• refined license information

New information

• door type
• device type for vanity basin fitting activation

R2RML mapping

This mapping allows the usage of R2RML processors like sparqlmap to reuse/transform the CSV file. For instance, to map it into RDF.

New information:

• ramp gradient
• information about support handles besides the WC (available, left or/and right)

Updated version of the dataset which contains more accurate lift information. In some buildings there is not enough space (turning circle) to leave a lift, therefore the value for “Personenaufzug-rollstuhlgerecht” is set to “teilweise”, if that is the case.

Updated data based on latest changes by the BVL.
