Escher was a PHP MVC framework developed by Thom Stricklin from 2011-2013. Escher implemented a hybrid of Model2 MVC and PAC architectures and CMS concepts as well as plugins and configuration wizards. Development halted in 2013 in favor of Kohana and later Symfony, which closely aligned to the same design principles as Escher.
Revamp model schemas to account for storage requirements, default values, keys, etc.
Also create DB (or datasource?) functions to convert a schema to DB statements for creating or modifying a table.
