2. EMI Mission Statement
The European Middleware Initiative (EMI) project represents a close collaboration of the major European middleware providers - ARC, gLite, UNICORE and dCache - to establish a sustainable model to support, harmonise and evolve the grid middleware for deployment in EGI, PRACE and other distributed e-Infrastructures

8. The Requirement Process
EMI categorizes requirements in two classes:
Major requirements: new services, major interface changes of existing services, support for new platform requiring substantial modification to major services, etc
Minor requirements: any change to improve a service that keeps backward compatibility and is limited in scope to subsets of the whole EMI distribution
Major requirements are discussed through high-level collaboration bodies like the EGI TCB or the WLCG MB and normally have to be provided before a major release cycle starts
Minor requirements can be submitted at any time by anybody
Once a requirement is in principle accepted, any technical discussion needed to implement a solution is discussed directly with the original proposer, who must also engage in validating and using the solution when available

9. EMI and GISELA Requirement from GISELA can be submitted to EMI:
Via existing high-level bodies, like the EGI TCB
Directly
EMI is happy with either solution, but we would prefer the first:
It is already a managed, tracked collaboration
Acts as a central coordination place where duplicate or conflicting requirements can be filtered out and proper prioritization discussed
However, for requirements coming from GISELA, we would like to establish a direct technical channel to discuss about implementation and validation for accepted requirements

10. EMI and GISELA
Possible requirements or collaboration areas of interest to EMI from the GISELA workplan:
Support and Customisation of Already Available Services
Development and Support of New Services
and in particular:
gLite port to Windows OS
gLite-ourgrid interop
app services on top of gLite (e.g. monitoring & control of WN jobs)
adoption of gLite security mechanisms in ourgrid

11. EMI and GISELA Next steps: Agree on the best collaboration model
Identify which of the aforementioned technical areas are:
Requirements
Collaboration areas
Agree on a number of realistic tasks that EMI and GISELA can run together for mutual benefit
Sign an MoU describing the tasks and some reasonable milestones
