Hurdles

“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
