Purpose of processing

ALOE-IAO makes a platform available to users who wish to save and manage digital resources and links in a personal account.

Every user can decide whether to save a resource or link for him or herself, for members of selected groups or publicly for other users. ALOE-IAO makes it possible to organize such links and resources in a variety of ways, to exchange them with other users, to evaluate them, and to provide them with personal comments.

Access data collected by ALOE-IAO

For a variety of offered functionalities, ALOE-IAO stores information in a special database table for the collection of the action history when they are accessed.

On every access/retrieval the following data are stored:

  • Unique identifier of the executed action
  • Unique identifier of the requesting user (only if logged in)
  • Unique identifier of the object concerned (only if it exists)
  • Type pf the concerned object (e.g., a digital resource, a group, or another user)
  • Access date
  • Additional metadats (optional, e.g., metadata provided when contributing contents)
  • Visibility of the action rgearding the provision to others (private, only for members of a group, only for members of a group but without information about the user, public, or public but without information about the user)
  • Unique identifier of the group, if the visibility was restricted to members of a group
  • Access type (via web browser or external client)

These data are need to generate the offered push information (via feed or email) about activities concerning specific contents as well as about activities on own contents.

Using the visibilities assigned to the different actions in ALOE-IAO is is automatically ensured that only such information about activities of a user is made available to others, when it is also visible for any anonymous user in the system (e.g., the contribution of public content or a comment).

The stored data records can be statistically evaluated in order to answer specific research questions and to adapt and optimize ALOE-IAO to the needs of our visitors.
