PDS Use Cases
Add card from gallery
Note: Cards represent a relationship between the user and an external site or business. The relationship includes a bi-directional data channel that shares and synchronizes a site-specific set of attributes between the site and the user's PDS. This set is a subset of the user's overall set of attributes.
- She navigates in web client to a place where a gallery of available templates is displayed
- She clicks on the "Google Ads" card-shaped template
- She sees a new Google Ads card in her list of cards
- Alice is already logged in to her PDS web client
- The PDS includes a card gallery
- PDS gallery is pre-configured with a set of template contexts and one of these is the Google Ads template.
- Template vocabulary shows an example template--this example is the Google Ads template
- Q: How does the PDS code know by inspection of the card gallery whether the PDS user is the definer/creator of the template? In other words how does it know which role (definer vs. participant) it should play?
- A: If the card is in the gallery at all, we will assume it was defined by an external (non-user) definer. We'll put user-defined templates somewhere else.
- Q: how is the connectionType for the Proxy determined from the template?
- A: See Template vocabulary#UML_Overview--the tempalte has a proxy:connectiontype attribute whose value should be copied to the Proxy.
- Flow stars in the cline (aka portal). User opens the card gallery. User selects card to add.
- Client instantiates the participant context based on the Participant prototype in the template
- Client instantiates the definer context based on the Definer prototype in the template. It also adds an h:correlation link from the newly minted p:Person in the Definer context to the p:Person in the Participant context
- Client adds the reciprocal h:correlation link
Edit simple attribute of a card
- She navigates to a place that shows her list of cards
- She clicks on a card (e.g. Google Ads") to select it
- The card displays a set of attributes including age-range widget
- Alice edits the value of the age-range widget
- Alice logs into web client
Create a connection with a site
User goes to a site that allows a PDS-to-site connection. (We're being vague here about the protocol because we assume it can entirely be done using the hot-off-the-presses OpenID Connect protocol, but we're not yet sure).
