NASA High Dependability Computing Program (HDCP) is a distributed project. Its members are located in different places and have to communicate with each other frequently, and share information and knowledge in an easy and efficient way. Project members need to be informed of the work of other teams and learn from each other's experience relative to the HDCP project. The HDCP community of practice also needs an online space to "meet" and collaborate - an environment to exchange ideas, to ask questions and receive answers.

These pieces of knowledge must be captured, organized, efficiently shared, and reused within the project, since some tasks might be repeated, either by the same team or at other locations.

Researchers need to have permanent access to the shared knowledge, namely the dependability models and metrics, and the HDCP experiments, interventions and testbeds.

The HDCP web-accessible knowledge/experience base (KEB) addresses these needs. It is an online repository containing:

• Knowledge and experience specific to HDCP about technologies and interventions developed by HDCPers and testbeds that are used in this project
• Knowledge related to dependability and methods and models developed within HDCP more
• Knowledge related to empirical studies and HDCP experiments
• Information on HDCP members more
