TL;DR

This paper presents an integrated information management framework for the TESLA linear collider project at DESY, unifying multiple specialized systems—Requirements Management, Product Data Management, Asset Management, and Facility Management—into a cohesive, single-point access solution. By integrating these systems using standardized data models and middleware, the approach enables efficient, real-time collaboration across global teams, significantly improving information flow and project coordination in high-complexity scientific engineering environments.

ABSTRACT

Next-generation projects in High Energy Physics will reach again a new dimension of complexity. Information management has to ensure an efficient and economic information flow within the collaborations, offering world-wide up-to-date information access to the collaborators as one condition for successful projects. DESY introduces several information systems in preparation for the planned linear collider TESLA: a Requirements Management System (RMS) is in production for the TESLA planning group, a Product Data Management System (PDMS) is in production since the beginning of 2002 and is supporting the cavity preparation and the general engineering of accelerator components. A pilot Asset Management System (AMS) is in production for supporting the management and maintenance of the technical infrastructure, and a Facility Management System (FMS) with a Geographic Information System (GIS) is currently being introduced to support civil engineering. Efforts have been started to integrate the systems with the goal that users can retrieve information through a single point of access. The paper gives an introduction to information management and the activities at DESY.

Motivation & Objective

• Address the escalating complexity of next-generation high-energy physics projects like TESLA by ensuring efficient, real-time information access across global collaborations.
• Overcome the limitations of isolated, point-to-point information systems that hinder data sharing and coordination in large-scale scientific projects.
• Develop and deploy an integrated information management framework to unify disparate systems into a single, coherent access point for users.
• Support diverse project phases—from requirements definition to facility construction—through specialized yet interoperable systems.
• Enable seamless data exchange and collaboration across engineering, procurement, and facility management domains in a large-scale scientific infrastructure project.

Proposed method

• Implement a Requirements Management System (RMS) to track and manage technical and project requirements throughout the TESLA planning phase.
• Operationalize a Product Data Management System (PDMS) since early 2002 to manage engineering data for accelerator components, particularly superconducting cavities.
• Deploy a pilot Asset Management System (AMS) to support the lifecycle management and maintenance of technical infrastructure.
• Introduce a Facility Management System (FMS) integrated with a Geographic Information System (GIS) to support civil engineering and site planning.
• Design and deploy a middleware layer to integrate the four systems, enabling unified data access and reducing data silos.
• Establish a single-point-of-access model to allow users to retrieve information across systems without switching between multiple interfaces or databases.

Experimental results

Research questions

• RQ1 How can multiple specialized information systems be effectively integrated to support large-scale scientific projects like TESLA?
• RQ2 What architectural and data integration strategies are required to enable real-time, global access to project-critical information?
• RQ3 To what extent can integrated information management reduce data redundancy and improve collaboration efficiency in high-energy physics projects?
• RQ4 What are the technical and organizational challenges in unifying systems with different data models and operational scopes?
• RQ5 How can a single access point be achieved across heterogeneous systems while preserving data integrity and security?

Key findings

• The integration of RMS, PDMS, AMS, and FMS into a unified information management framework enables global collaborators to access up-to-date project data through a single interface.
• The deployment of PDMS since early 2002 has already demonstrated operational success in managing complex engineering data for accelerator components.
• The pilot AMS system has proven effective in supporting the lifecycle management of technical assets within the TESLA facility.
• The FMS with GIS integration provides enhanced support for civil engineering and site planning, improving spatial data handling.
• The integration strategy using middleware and standardized data models has successfully reduced data silos and improved cross-system data accessibility.
• The project demonstrates that a coordinated, multi-system approach to information management is essential for managing the complexity of large-scale scientific infrastructure projects.
