Software Update:Metadata Discovery

Checking Schedule

Gateways into update checking:

• once per day regular
• on startup unless a check has been performed in the previous hour
• UI in Tools menu, Options window

The former catches the case where the browser is left running... The latter catches the installation of build where there are patches available, and more immediately checks for updates for most users.

Update Format

Currently RDF

• make platform selection more robust to avoid updating a platform to a different platform

Update Determination

• Scheme for determining any update as a positive/negative relationship. e.g. Simple version-version updates, downgrades, branch hops, etc.
