Just wondering if all that JMDL stuff is now incorporated as part of MstnAPI.
Class com.bentley.dgn.ArcElement now rebooted as Bentley.Geometry.Common CircularArc?
All that JMDL Schema and Component stuff now part of ecsdk?
Unknown said:... that JMDL stuff ...
JMDL was an implementation of the Java byte interpreter inside MicroStation/J. It never made it to MicroStation V8.
The article you cite mentions ProjectBank. ProjectBank was an innovative transactional extension to MicroStation. It was informed by relational database theory and included a forerunner of today's EC Schemas.
MicroStation customers are conservative and didn't take to ProjectBank. However, Keith Bentley's forward thinking (for ProjectBank was his brainchild) helped to pave the way for the SQLite technology you can now use on your mobile device.
Unknown said:One of the benefits of using Schemas mentioned all those years ago was that the Schema can be extracted in different file formats tailored to different tasks/apps
A schema defines data. It is not the data itself. When a schema is available, an app. can use those formal data definitions to do something meanful to that app. The 'something' might be to write a file in a specific format. It might be to extract engineering data — ignoring other data — to perform some kind of analysis.
An EC schema is directly analogous to a relation database schema. It helps an app. to figure out automatically what data can be used for a given purpose.
