Viaduc originated as a development project for the online access of the Swiss Federal Archives (SFA). The online access of the SFA can be described as a digital reading room: it can handle most of the archive's public accessibility tasks on its digital platform (see the platform's user manual).
Its hightlights comprise the following features:
- Search in public metadata and primary data.
- Search in protected meta- and primary data for authorized users.
- User authentification and differentiated levels of access to metadata and primary data.
- Downloading primary data as a working copy, in DIP (Dissemination Information Package) structure.
- Ordering digital copies of archival records.
- Preparation of the working copy includes
- OCR recognition of scans
- Format conversion from archive to user formats
- Storage of public working copies in a cache
- Issuing requests for consultation of protected files
- Temporary access to documents by authorized persons upon request
- Government offices have access to their own documents
- Backend application for order management, consultation requests, administrative access and other settings.
In order for the archival community to benefit from the investment, knowledge and solutions to various problems, the SFA has decided to make the source code available.
The complete solution of the online acces includes 4 code repositories.
The repository cmi-viaduc-web-core is an Angular library.
This library is used by the other two applications, Public Access (cmi-viaduc-web-frontend) and Internal Management (cmi-viaduc-web-management), as a common code base and component library.
The frontend applications are hosted in an ASP.NET container (see backend repository cmi-viaduc-backend) and communicate with the system via a web API.
This code has been developed in the specific context of the Swiss Federal Archives. It includes in some places hard-coded links to several services used in this context, namely
- URLs to pages of other federal administration services ( *.admin.ch )
- URLs to the public-client and to the management-client ( https://www.recherche.bar.admin.ch.*)
- URLs to authentication services (E-IAM and Swisscom) ( https://www.recherche.bar.admin.ch/private | https://dis.swisscom.ch/* )
- URLs to chatbot and co-browsing services (https://chatbot.bar.smartive.cloud/* | https://unblu.cloud/unblu/* )
Replace them as needed to adapt the code to your specific environment.

The initial development project is finished; currently the online access of the SFA is in the maintenance/continuation phase. It is planned to make selective developments, corrections and improvements every year and to publish them here.
This repository is a copy which will be updated regularly - therefore contributions via pull requests are not possible. However, independent copies (forks) are possible under consideration of the AGPLV3 license.
