Compendium-TA supports user defined entities.

It is easy to define your own entities with defined attributes, to structure your data.

Entities can be displayed in lists and filtered so you only see the ones that you require.

Cross referencing entities can be done by drag and drop or using the Cross Reference Matrix functionality

You can define scripts for entities too. You can use Compendium-TA as a flexible framework for entering, organizing, and processing your information.
