BCF 2.0 Improvements
Extension.xsd
• Hard to agree on a common set of parameters and their allowed values.
• Additional schema to provide
enumerations to several
parameters as TopicType, TopicStatus, TopicLabel, SnippetType, Priority, UserIdType, • Enumerations are project
related

BCF 2.0 Improvements
BIM‐Snippets
• Any type of file (e.g. Simple IfcXML) that can be attached to a topic and exchanged between
applications
• Clash, PfV, Opening, Simulation Result ….
• A BIM‐Snippet can be schema
based (MVD, addOn)
• A BIM‐Snippet can be external
(URL) or internal (bcfzip)
