The application is currently in pilot operation. Please send us your feedback.

Metadata are data about data. They enable the classification and exploitation of external data. Further information regarding Metadata can be found on the RWTH Website.

The MetadataManager gives you the possibility to generate metadata according to the scheme created for your setup. The scheme specifies which input field of metadata (author, subject,...) needs to be filled out. It is designed to help you with controllig your vocabulary: Selecting predefined terms ensures that no typographical errors occur or that different terms are used for the same subject.

Choosing an appropriate scheme or constructing one is very important. The FDM Projectteam will gladly support you with this.

The MetadataManager does also enable you to set a Persistent Identifier (PID) to associate data with metadata and to link them to other locations.

1. Login


After accessing the website you will have to log in. The login works with Shibboleth and OAuth. Please follow the instructions.

 Here you can find a detailed describtion of the login process

To sign in with Shibboleth, you have to enter your username and password and click on the "Login" button.

When you sign in for the first time, you need to confirm the data which is sent to the MetadataManager.

Afterwards you need to authorise the application.

After successful authorisation, you can return to the application.

2. Start


On the front page you can select a metadata scheme to file a new set of metadata or - in case they were saved - the last metadata you have used.

Depending on your institute's index number (Institutskennziffer/IKZ) there are different metadata schemes you can use.

If there is no metadata scheme deposited for your institution, please contact us. We can work on an appropriate scheme together and provide it for your institution.

3. Persistent Identifier (PID) and access token


A persistent identifier (PID) enables you to associate data with metadata and therefore to link data to other locations.

Besides the PID, a distinct access token (OTA) is generated for each metadata set. Regardless of the visibility settings you specified for that metadata, you allow users to read, edit and delete that metadata set by passing the OTA to them. Please consider that editing the OTA is not possible at the moment. Therefore, treat the OTA with adequate discretion and do only pass it on to trusted persons.

PID and OTA are automatically generated while saving the metadata set and can be accessed via the edit view of the corresponding metadata set.

Fill in the field "Data URL" with the storage location of the data you want to use. The "Metadata URL" will be filled automatically.

4. Generating Metadata


Fill out the fields of the metadata scheme.

Additionally you can specify the groups of people who are allowed to see the metadata. Choose "private" if the metadata should only be viewable by you. Choose "institute" so other employees of your institute are able to see the metadata. If you have to share the metadata publically, choose "public".

If you belong to multiple institutes, you can select the institute you want to share your metadata with by their IKZ.


5. Saving the Metadatafile


The "Save"-Button saves your metadata in the database (integrated workflow).

6. Manage Metadata


By clicking on the "Manage" tab in the MetadataManager, you can administrate your metadata. When you click on an entry you will be redirected to an edit view.

7. Store and access data for archival


It is possible to provide data belonging to your own metadata sets for persistent long time archival in the simpleArchive at RWTH Aachen. In order to do so, simply click the button to the right of the "Data URL" field and you will be redirected to the archive page.

You can do the same by clicking on the button in the referecened data column on the manage page.

On viewing or editing your own metadata sets you have the opportunity to access the provided files in simpleArchive. The simpleArchive file field will now show the reference for the provided files and the button next to it will redirect you to the restore page for that file.

8. Search Metadata


When you click on the "Search" tab in the MetadataManager, you can access the metadata search function. You can enter values according to which you want to filter the results. When you click on an entry you will be redirected to a page where you can edit your own data and look at the data provided by others.

Furthermore, you have the option to find metadata sets belonging to a specific OTA. Since the OTA is created distinctly for each metadata set, other search criteria are being disabled as long as you use the OTA as search criterion. If you want to continue the search using other criteria, simply remove the OTA from the search.


9. Update Metadata


On editing the metadata, you are redirected to the "Submit" page where you can change the values of the metadata set and save them with the help of the "Save" button.

It is always possible to edit your own metadata sets and to allow other trusted persons to edit one of your metadata sets by conferring the corresponding OTA.

However, at the moment it is not possible to change the OTA, so be considerate as to whom you confer the OTA.

10. Download metadata as a file


On the same page you can download the set of metadata as an RDF-formatted XML file. Just click the link contained in the "Metadata URL" field.

11. Show metadata by other authors


In the picture on the bottom you can see the view for metadata created by other authors.
