Mesh services allow web applications to access a user's social graph and storage from desktop devices through synchronization. The Live framework provides tools and APIs to build, deploy, run, and update these "mesh-enabled" web applications, giving them offline access and the ability to integrate with a user's social activity and connected devices. Updates to mesh applications are automatically synchronized across all user instances for easier management by developers and use by customers.

3. Mesh Services extend Web applications into Desktop by providing
Access to Live user Social Graph, Synchronized Storage and
Offline Access
Live Services add Value to various Stages of application
Development and Use Lifecycle
Live Framework provides Runtimes, API Kits, Resource Model, Tools
and Controls to Build, Deploy, Run and Update Mesh-Enabled Web
Applications

19. All about putting users in control of their data and apps
Application Secure Context
• Apps not allowed to access disk, other apps and user private data
• User can explicitly grant permission to private data
Offers & Roles (Read, Write, Full)
• Standard: Contacts, Profiles, News, LiveMeshFolder
• Custom Offers: <Custom Type> of Mesh Objects (promotes app type sharing)
Client Sandbox: Shared secret and cookies isolate each application
Live Desktop Sandbox: Cookies, Iframe and domain isolation

22. Application ID • Uniquely identifies a Live Mesh Application
Secret • Used to authenticate a third party website
• Permissions can be managed at Mesh Object, Profiles, Contacts and
Resources Mesh Application level
• Privileges requested/given to third party web sites
Roles & Offers • Read, Contribute, Own
Consent Request • A request by a web site to get access to a Mesh resource
• User explicit permission to an application to access his/her data &
User Consent applications
Delegation Token • An encrypted token representing a granted consent
Refresh Token • Used to refresh a token for a granted consent

23. Updating Applications is a pain point for developers and end-
users
Mesh Auto update service updates all the instances of a
Mesh App upon use
Triggered when developer uploads a new version into
Application Catalogue
Auto update is optional (user decides whether and when to
update)
App Catalogue stores and renders multiple versions of an
application

24. Global Store for all Mesh-Enabled Web Applications
