Using Brick and RealEstateCore Together

Using Brick and RealEstateCore Together#

Note

Brick-REC integration was introduced in Brick v1.4 and expanded in v1.5.

This document summarizes the changes to Brick that allow it to be used in conjunction with RealEstateCore (REC).

Locations#

All Brick Location classes have been deprecated as of 1.4 and replaced with equivalents in RealEstateCore. These deprecations appear like this in the Turtle file:

brick:Building
  owl:deprecated "true"^^xsd:boolean ;
    brick:deprecatedInVersion "1.4.0" ;
    brick:deprecationMitigationMessage "Brick location classes are being phased out in favor of RealEstateCore classes. For a replacement, consider rec:Building" ;
    brick:isReplacedBy rec:Building ;
.

The brick:isReplacedBy property indicates the REC class that should be used in place of the deprecated Brick class. Using a Brick class in a Brick model will raise warnings, not errors, during SHACL validation. SHACL rules included in Brick will also add the new REC class to the model, so that the model is still valid.

Relationships#

Brick relationships have been mapped to REC relationships where possible.

See this table:

Collections#

Note

This section describes changes introduced in Brick v1.5.

As of Brick v1.5.0, brick:Collection has been deprecated in favor of rec:Collection to remove redundancy between the two ontologies. Custom collections should now be typed as rec:Collection and use rec:includes to express membership:

@prefix rec: <https://w3id.org/rec#> .
@prefix : <urn:bldg#> .

:my_collection a rec:Collection ;
    rdfs:label "All of the dampers" ;
    rec:includes :dmp1, :dmp2 .

All built-in Brick collection classes (e.g. brick:HVAC_System, brick:Air_Loop, brick:PV_Array) are now subclasses of rec:Collection rather than the deprecated brick:Collection.
