End of the 2nd phase: end of 2013
5 years of development
first a demonstrator version to get feedback
suggestions went into further development

Definition in legal document of the US Federal Government (1994)
SDI as a minimum infrastructure, includes applications, standards, technology and institutional governance necessary for effective and efficient spatial data and services management within or across organizations.
SDI on different levels (e.g. Europe: INSPIRE, National: GDI-DE)
The concept of National SDI (SDNI) is now being universally called the Spatial Enablement of Governments and Societies (UN Declaration from Kuala Lumpur, 2011)

Potential for a SDI
Pros
availability
support of Standards
Service Orientated Infrastructure
adoptable for other regions
easy to transfer to other server due to Virtualization
platform for further development
Cons
no synch between instances of the system
performance must be tested for larger scale application
