Deletion of course rooms of the summer semester 2023
In line with the life cylce of course rooms with connection to RWTHonline, the summer semester 2023 course rooms were deleted on May 5, 2026.
Deleting Folders
At times, it was not possible to delete empty folders. The development team has resolved this issue, and the update addressing it will be deployed within the next few days. Once deployed, empty folders can be deleted manually, and all existing empty folders will be automatically removed by the Coscine team. When deleting folders manually, please note that deleted items are not permanently removed from the system until seven days after the deletion date.
S3 Policies
The Coscine documentation has been expanded to include a page on S3 policies [4] in response to an increasing number of user inquiries on this topic. The new page is aimed specifically at power users and provides a concise overview of the policies that have been set. It also highlights which policies are intentionally not supported.
TS4NFDI Incubator
As part of the TS4NFDI Incubator, the AIMS project is currently working to improve federated search in order to enable more precise and detailed results from ontologies. Users can choose from domain-specific collections that bundle ontologies from various NFDI consortia (e.g., NFDI4Ing, NFDI4Chem, FAIRmat). In addition, widgets for improved visual representation are being integrated.
The goal of the incubator is to facilitate the use of standardized terminologies and to make the user interface even more user-friendly. Further information is available in the dashboard.
Changes to the Privacy Policy and Terms of Use
Due to a new feature, we will be updating the Privacy Policy and Terms of Use. Starting in early June, it will be possible to integrate stored metadata into community-specific searches (e.g., subject-specific searches for engineering) and thereby build a knowledge graph. The Coscine knowledge graph can also be searched using SPARQL queries. This feature will be available for all metadata stored in Coscine, provided that the visibility of a project or resource is set to “Public.” If you do not wish to use this feature, please set the visibility of your projects and resources to “Project Members.” A prompt asking all Coscine users to reconfirm the Terms of Use after logging in to the platform will be displayed starting next week.

New Model (GPT-5.2), Incident Integration, and Improved Document Search
- New Language Model:
- Ritchy now uses GPT-5.2 by OpenAI as its underlying language model. Compared to the previous GPT-4.1 model, it provides improved reasoning capabilities and a deeper understanding of language.
- Automatic Integration of Incident Reports:
- Ritchy can now automatically detect whether a user request relates to a current incident or maintenance activity of the IT Center. If a match is found, the corresponding incident report is directly incorporated into the response, including status information and a link to the incident page. Incidents are prioritized by severity (incident > partial incident > maintenance > warning > notice).
- Improved Document Search:
- The way Ritchy accesses the IT Center documentation has been fundamentally redesigned. The search now uses a three-stage approach (keyword search, vector search, and semantic re-ranking) to retrieve more relevant articles. In addition, more document context is included in responses, resulting in more precise and complete answers.
- More Reliable Language Detection:
- Automatic language detection has been made more robust. In particular, for queries containing English technical terms (e.g., product names like Cisco AnyConnect), the system now more reliably identifies the user’s actual language and consistently formulates the response in that language.
- Structural Improvements:
- The internal architecture of the application has been modularized to simplify future extensions and maintenance. These changes do not result in any visible differences for end users.
