Possible enhancements through a semantic web approach

1. What have we made available?

2. Using the information in applications1. Querying

2. Reasoning

3. Parallel descriptions of information

Relying on semantic web descriptions can address interoperability issues in construction industry more appropriately

BUT: A lot of work still needs to be done!
