“The user cannot find the data;
If he can find it, cannot access it;
If he can access it, ;
he doesn't know how good they are;
if he finds them good, he can not merge them with other data”

Next Steps:
• Continue to work with AQ community to improve the AQ-specific sections needed for sharper discovery
• Work with AQ data providers to register their services in the AQ Community Catalog
• Extend metadata unstructured user-contributed content through DataSpaces
