Timeline for the Timeline for the Design StudyDesign Study The preparation of the proposal will be

managed within ILIAS-N5-GWA-WG3 WG3 will realize a skeleton version of the

Design Study proposal within two months, i.e. in 2006.

Call an open meeting of WG3 to look for (new) collaborators

Distribute writing workload onto subgroups Prepare a first draft version until end of

February. Call for Proposals closes about middle of April.
