I can only second Gustaf's comment. The ::xo::db layer is great an works beautifully (XoDynfields is build upon that work). The missing pieces (although some only makes in context of dynfields):
- Extension tables: object_types can have extension tables in which attributes are stored. These are currently not supported by ::xo::db::*
- Support for multivalue
- Support for categories
- Attribute Elements (which are used to generate the form), taken from Dynfields
This is what XoDynfields has tackled, but if you need none of them or are fine with manually creating your forms, then off you go.
Also, if you want to use the website to extend your class then a proper user interface is missing (okay, im_dynfields provides that).
