I'd like to use ${app} to store a database. Users are invited to created personal versions of the database in ${user} by copying record items from the master database in ${app}, update them as well as adding new records to ${user}.

This design intent of this mashup is to serve as a data feed "builder" tool. The users will want to access the information in their ${user} feed externally to use in other applications.

so the questions are: 1. can ${app} be initialized in a separate function or application (possible with a polling schedule for refreshes) so that the master database feed does not have to accessed from my server and processed by GBase each and every time a user logs on to the mashup?

2. Can the user's personal database in ${user} be accessed *externally* by that user (and/or public) - optimally via GBase queries on the snippets feed? ... I guess it would be just like it is now but instead of someone owning the items in GBase they would would be "owned" by a mashup application and thus indirectly by the user of that mashup.

(i hope that makes sense and is not a too stupid question...) thanks, jack
