Product development
elasticLM: Software Licensing and License Management
elasticLM is a novel technology for creating and managing software licenses designed for distributed computing environments like Grids, Clouds or SOA.
Of course, the benefits of elasticLM are also available when using elasticLM for applications running on local resources, e.g. workstations or clusters.

WSAG4J: Standards-based Java framework for negotiation, creation and monitoring of Service Level Agreements
The WS-Agreement for Java framework is a tool to create and manage service level agreements (SLAs) in distributed systems. It is an implementation of the OGF WS-Agreement standard.
WSAG4J helps you to design and implement SLAs for your services and automates typical SLA management tasks like SLA offer validation, service level monitoring, persistence, accounting, and more.

Curriculum vitae
Since 1987 Wolfgang Ziegler is a member of the scientific staff of the Fraunhofer Institute for Algorithms and Scientific Computing (SCAI) led by Prof. U. Trottenberg. SCAI formerly was one of the institutes of the German National Research Centre for Mathematics and Informatics (Gesellschaft für Mathematik und Datenverarbeitung). He joined the department of bioinformatics (led by Prof. Martin Hofmann-Apitius) in 2005 as head of Grid Middleware Research Group. His research areas are Grid Computing, Resource Management und Scheduling, Management of Virtual Organisations, and Service Oriented Architectures. He was active in the US Grid Forum since 1999, he was a co-founder of the European EGRID in 1999 and since 2001 he was co-chairing several working groups of the Global Grid Forum (now Open Grid Forum). Currently he is co-chairing the Grid Resource Allocation Agreement Protocol Working Group (GRAAP-WG), which develops WS-Agreement, a proposed recommendation for an XML language for specifying a service level agreement between a resource/service provider and a consumer, and a protocol for creation of an agreement using agreement templates. He is also active in the OGSA-RSS working group and the Grid Scheduling Architecture Research Group (GSA-RG). He has been involved in programme committees of a number of conferences and workshops in the field of Distributed Computing and Grids. He was programme co-chair of the UNICORE summit co-located with the EuroPar 2006 and 2007. He is currently participating as work-package leader or coordinator in several national and European Grid projects, e.g. D-Grid, the CoreGRID Network of Excellence, the Integrated Project PHOSPHORUS, and the SmartLM project.
