Learning Object Metadata for Data Collection

1 Initial Problem

Currently, not every type of object in ILIAS can carry LOM. Among the objects not supporting LOM at the moment is the Data Collection.

2 Conceptual Summary

Support for LOM is added to the Data Collection.

As a side effect, Data Collection will then also support Taxonomies better, since their 'Metadata' tab will always be shown.

3 User Interface Modifications

3.1 List of Affected Views

• Data Collection > Metadata

3.2 User Interface Details

Data Collections will have a tab 'Metadata' with subtab 'LOM', which will always be shown. Like for all other LOM-enabled objects, the subtab 'LOM' contains the quick edit form for the object's LOM, as well as a button leading to the full LOM editor (see Moving LOM Metadata Editor to Kitchensink for details).

3.3 New User Interface Concepts

No new UI concepts required.

3.4 Accessibility Implications

No known accessibility implications.

4 Technical Information

As for all other objects, the LOM fields general > title and general > description will automatically be set to the Data Collections's title and description and their respective languages (translations via Multilingualism excluded). No other LOM fields will be filled automatically.

The required infrastructure for this mechanism is already implemented in the Object service (see e.g. ilObject::createMetaData), and just has to be used in the Data Collection. For details, see here.

5 Privacy

No personal data is automatically stored in the LOM of Data Collections. For information about what personal data can be entered manually into the LOM of an object, see the privacy information of MetaData.

6 Security

No foreseeable security implications.

9 Discussion

JourFixe, ILIAS [jourfixe], 18 MAR 2024: We highly appreciate this suggestion and schedule the feature for ILIAS 10.

10 Implementation

Implemented as described above, Data Collections now support LOM as other objects do. They have a 'Metadata'-tab where the LOM editor can be accessed, their title and description is synchronized with the respective LOM fields, LOM is shown on their Info Page, fields like keywords are found in the search, LOM persists through export/import and copying, etc.

Note that the subtab 'LOM' is only actually displayed if it's not the only subtab. For the case of the Data Collection there is only a second subtab if it is in a Container with Taxonomies enabled.
