The Entity Construction Kit (ECK) provides a user interface and an API for creating and managing custom CiviCRM entities. In conjunction with custom fields being attached to those entities, things in your business logic can be modeled more clearly, when standard CiviCRM entities are not sufficient.
ECK allows you to define arbitrary semantics as a CiviCRM entity type, each with a name and a label, and as many properties as you like by attaching custom fields to them. You can also introduce another level of hierarchy by defining sub-types.
As instances of those entity types are "real" CiviCRM entities, other extensions can build upon that data model. E.g. the SearchKit extension can be used to create search forms, overview pages, etc., and the FormBuilder extension can be used to create forms for editing properties or linking entities.
Also, other extensions are able to attach their functionality to those entities. E.g. the CiviResource extension can be used to mark entities as resources that can then be assigned to resource demands for e.g. events.
The extension is licensed under AGPL-3.0.
This CiviCRM extension is provided as Free and Open Source Software, and we are happy if you find it useful. However, we have put a lot of work into it (and continue to do so), much of it unpaid for. So if you benefit from our software, please consider making a financial contribution so we can continue to maintain and develop it further.
If you are willing to support us in developing this CiviCRM extension, please send an email to info@systopia.de to get an invoice or agree a different payment method. Thank you!
