PDS 2.0
{{#eclipseproject:technology.higgins|eclipse_custom_style.css}}
The Personal Data Store 2.0 is a web service that stores personal data on behalf of an individual.
The PDS is a variant of the IdAS Proxy Service, with the following changes:
- The UDI Resolver is configured to support sync:// UDIs.
- The IdAS Registry is configured to include the RDF2 Context Provider.
The IdAS Proxy Service is layered over the Attribute Service 1.1 to provide a bi-directional, synchronizing XDI endpoint over data managed by Context Provider plug-ins to the IdAS package. These context providers area also data adapters to a variety of back end data stores.
Access to user's personal data
The Personal Data Store 2.0 provides access to the user's personal data. These data are represented as a number of Contexts adhering to the Higgins Persona Data Model 2.0, which can be used for storing arbitrary (identity) data. UDI references are used for representing "links" between Contexts, both inside the Personal Data Store 2.0 and to external data sources.
The following diagram shows how apps can access the PDS endpoint over XDI. The diagram shows four contexts that backed by external data sources: Google Contacts, Medical Records, an RDF store and an enterprise LDAP directory:
