  1. How to avoid coming unstuckSteve Fisher / RAL www.eu-egee.org EGEE is a project funded by the European Union under contract IST-2003-508833

  2. Computing Element Retain! Retain Get rid of it This is separate – good (I would prefer “status”) Why separate Info, Policy and ACPB

  3. Site and Service Why is ServiceStatus not separate

  4. Host etc This complexity does not help us at all – it is not for batch farms. If this remains in schema our info providers should not touch it.

  5. A few more details • The document must define all attributes precisely • e.g. Authorization Rule • Too many optional arguments • How to interpret null? • Best avoided – otherwise meaning of null must be defined • Is the assumption that a CE is bound to a single VO good? • I am concerned to avoid models which are not easily mapped to relational model. Should probably also ensure easy mapping to hierarchical model. • We want something simple • It is hard to get where we want without starting again • Tweaking won’t work

  6. SuperGLUE In relational model all except site linked by endpoint URL Can we make it as simple as this? Site * CE Service SE CEStatus ServiceStatus SEStatus
