At the heart of bSDD is a canonical database, where all dictionaries can be related to each other. The main way to access the bSDD is through itsAPIs (Application Programming Interfaces). This is how most BIM software and other apps can use the data stored in the bSDD. Apart from that, there isthe bSDD Search page, where people can look up the content. Authors can publish content to bSDD throughthe API orthe bSDD Manage portal. To upload, please register your organisation usingthe organisation registration form.
