-Collections is the feature designed to make data portable among Blockstack applications. Sharing is accomplished by storing a user's data in a standard, structured way in a known Gaia location. Collections associate the data with a user's distributed ID. When users move among apps, the same data is available to each application.

Collections associate user data with a user's decentralized ID. When users move among apps, the same data is available to each application the user authorizes.

-One of Blockstack's goals is to give users true data ownership by enabling *data portability*.  Data portability allows users to login with their digital ID on any app and have access to the same data. For example, if a user adds a photo of a Hawaiian vacation in one app, that photo enters the user's data pool. Then, when the user opens a second app, that same photo is already in use because the user's digital ID login is identical for both apps.

 How do collections work? Blockstack builds a library containing commonly used data schemes. Developers use these classes and objects instead of creating their own, unique data schemes. Using a class from the collections library guarantees class data is stored in Gaia in that format; And, when retrieved, guarantees the same format is returned. This pre-release provides the `Contact` collection. A contact schema produces this structure:

 <p>For developers, collections can incentivize user adoption by reducing user friction.  Users can easily try new apps and move to them without the overhead or barrier of re-entering data.
