The EP2DC module affects the default stages for upload and deposit, as well as the page displayed when a unit of work that includes a remotely stored data set is retrieved.

==Data Upload==

As shown in the adjacent figure, the EP2DC plugin extends the default EPrints stages with an additional EP2DC stage for uploading experimental data.

The EP2DC stage for uploading experimental data includes an options (collapsed in the previous figure) that allows metadata associated with the test data to be entered. The fields marked with a red star are mandatory. As shown in the adjacent figure, one of these madatory fields defines the access control. This field affects the data retrieval process, as follows:
* Open—allows data retrieved from the EP2DC EPrints repository to be downloaded by anyone.
* Restricted to registered users—allows data retrieved from the EP2DC EPrints repository to be downloaded by by registered users.
* On demoand—data is supplied on request direct from the owner.

==Data Deposit==

The last stage in the EPrints default workflow is to deposit the unit of work (meaning all of the documentation, figures, etc. together with the accompanying data). The data will be deposited ataa remoted data centre, which is responsible for validating the data against the corresponding XML Schema Definition. If the data sets is validated and deposited successfully, a page similar to that shown in the adjacent figure is displayed.

As shown in the adjacent figure, when an item that has accompanying data is retrieved, in the case where a data set is unrestricted (meaning open access or accessible to registered users), there is an accompanying link to the data.

In the case where the data set is available on demand, a message can be sent to the owner requesting that a copy of the data set be provided.
