The document provides an overview of Arnaud Bouchez and his work on mORMot and SynPDF. It discusses mORMot version 1.18 and its features like being an ORM, supporting SOA, MVC, and REST. It then summarizes the results of a survey conducted on refactoring mORMot, including separating it into smaller units, using semantic versioning, dropping old compiler support, and moving to GitHub. It previews the structure and goals of the new mORMot 2 library.

Other Wishes
• Delphi Linux Support
• Focus on FPC
• More real world examples (DDD)
• Separate OS specific
• Make SynLog easier to use

45. mORMot 2 Survey
What we agreed on
• Semantic Versioning and releases
• Separate big units
• Composition over inheritance
• GitHub + https://synopse.info
• Main Delphi targets: latest 10.x + 7/2007
• FPC 3.2 / trunk premium support
• Eventual Delphi Linux

46. mORMot 2 Survey
What we agreed on
• Naming should be more consistent
TSQLRecord TSQLTableJson TSQLRest
• First iteration should be
backward compatible
(with some PUREMORMOT2 conditional)
• Later on, we may move forward
