Questions about the material's metadata

To change your material's metadata, go to your workspace and open the menu options (⋮) of the material you would like to customize. Select "Edit info" here.

In ZOERR, title, author/originator and license are mandatory data. They must be provided in order to publish a material. These indications are minimum information for the quality assurance of the materials and ensure that the materials can be found.
In addition, it is advisable to write a brief description of the material, supplementing its origin, type and language. For searching, it is helpful if keywords and a preview image are assigned.
Optionally, you can add further contributers and technical information for subsequent use to your educational material in ZOERR.

In the metadata dialog box (see question 1) you have the option of granting a license for the material you have provided. To do this, select "Manage License" in the License area. You can also access the same license dialog via the menu (⋮) and the "Assign a license" option.
In the following window you can choose between the licenses CC 0/Public Domain, CC-BY and CC-BY-SA.

In the "About the author" section, you have two options for specifying authors: Via the "General author information" or "Authors & Contributors" buttons. If possible, please select the option "Authors & Contributors" and name the specific person. If you are the author yourself, you can select "I am author of the material".
Furthermore, you also have the option of adding several authors and other people involved in the development of the material, e.g. editors, graphic designers within the same dialog box. To do this, select "Additional Contributers" below the input field.

A meaningful title is an important descriptive category of educational material. It facilitates the technical discoverability of the material and assists users in their search.

• Choose the title as precisely as possible and name the content as concisely as possible.
• Include technical terms in the title.
• If possible, avoid creative titles that do not specifically name the content. While they arouse interest, they may lure users down the wrong path.
• Avoid abstract terms such as Introduction, Lesson 1, Exercise Part 3.

Anything that cannot be included in the title can be used as a keyword. Because this can also increase the discoverability of the materials. Here are a few tips for assigning keywords:

• Assign three to seven meaningful terms/keywords.
• Use the keywords in singular.
• Use verbs in indicative and with a capital letter.
• Don't use word groups and phrases.

• Maintained and regularly updated vocabulary
• Avoid spelling mistakes / different spellings
• Coverage of synonyms (in parantheses)
• The same is found with the same terms

It may happen that you do not like the image generated by the system, or it could not generate one at all, such as with links. In these cases you can deposit a preview image. To do this, select the "edit info" menu option in the editing dialog box and click on the round button with the up arrow next to the image. Then you can select an image file that will be used as a preview image in the future.

For the "Origin" field, please always select the organisation to which you belong or through which the material was posted. This allows in the search environment, to view all materials posted by a university at a glance. The portal view of the repository adapted to a university also shows all materials originating from this university on the start page.
However, in the case of link objects pointing to external sites, this might not be appropriate. Here it is important to consider if it is appropriate to omit the origin in the metadata with the correct content or whether it is better to specify the college that entered the link so that these link objects can also be displayed in the hit list when searching for the college's materials. We can't give a definitive guide on this, ultimately it is the authors decision to make.

When right-clicking on a folder on the left in the workspace, you can select "Metadata Template" from the menu. In the following dialog box you can preset values for various metadata. In the case of materials that are newly imported into this folder, these values are already entered, changes are of course always possible. This functionality is intentionally not available for licenses and author names. Also note that the metadata template is not inherited by subfolders.

To add didactic metadata, open the metadata dialog "Edit info" first.

1. Type of Material: Here you can choose from a variety of material types that is suitable for your material, such as course, assessment, reference work, etc.
2. Audience: Select here to whom the material is primarily directed to.
3. Interactivity Type: In this case, you can choose from three options. Please consider the following explanations and choose the one, which is for your material most dominant.
   • Active learning (e.g., learning by doing) is supported by content that directly induces productive action by the learner. An active learning object prompts the learner for semantically meaningful input or for some other kind of productive action or decision, not necessarily performed within the learning object's framework. Active documents include simulations, questionnaires, and exercises.
   • Expositive learning (e.g., passive learning) occurs when the learner's job mainly consists of absorbing the content exposed to him (generally through text, images or sound). An expositive learning object displays information but does not prompt the learner for any semantically meaningful input. Expositive documents include essays, videoclips, all kinds of graphical material, and hypertext documents.
   • Mixed learning blends the active and expositive interactivity type in the object.
   Note: Activating links to navigate in hypertext documents is not considered to be a productive action.
