Higgins 1.0 and 1.1

Web Services

I-Card Manager

Thin client selectors use the I-Card Manager Google GWT-based app to provide a web interface to view, update and manage your cards hosted on the I-Card Service.

I-Card Service

Some selectors are designed as "thin clients" that only implement the user interface portion and rely on a hosted I-Card Service 1.1 for core functionality.

CardSync Service 1.1

A specialized bi-directional, synchronizing XML endpoint for synchronizing i-card data stored on a co-resident I-Card Service 1.1

Web Apps

Cloud Selector 1.1

Makes i-cards available as OpenIDs. It reads card data from the I-Card Service, so no client software is required.

Higgins 2.0 PDS

Under development for Higgins 2.0, the blue areas of the following diagram relate directly to the PDS:

Personal Data Store

The Personal Data Store 2.0 is a web data service that (i) stores personal data and (ii) acts as a proxy/gateway for personal data stored on other services. It can be accessed by:

• Sending XDI messages to its endpoint
• Using the following low level client libraries:
  • Org.eclipse.higgins.idas.client (Java IdAS Client)
  • Org.eclipse.higgins.idasclient.cpp.core (C++ IdAS Client)
• Using the PDS Client (under development)

PDS Client

The PDS Client 2.0 is code that apps may choose to use to access the Personal Data Store 2.0.

Authentication (AuthN) Service

The IdAS Proxy Service 2.0 and Attribute Service 2.0 require access tokens minted by the Authentication Service 2.0. Eventually the I-Card Service and CardSync Service will also rely on this external authN service.

Authorization Manager

• Authorization Manager (planned) gives the user control over the flows of data from a managed relationship card provider to a relying party. We plan to use/adapt Kantara UMA protocols.

Web Portal

• We plan to develop a Web Portal--an evolution of the Cloud Selector 1.1 from Higgins 1.1 with broader functionality.

Misc. Building Blocks

This section describes the data related services, java frameworks and data models that are used by the personal data agent services.

Data Models

• Data Models used in Higgins code and services

IdAS Solution

The IdAS solution is a testbed for exercising the IdAS Java framework.

• Higgins 1.1: See Higgins_1.1_Plan#IdAS_Solution_1.1
• Higgins 1.0: IdAS Solution 1.0: a basic configuration of the Identity Attribute Service 1.0 (IdAS). IdAS is a java framework that provides a common interface to identity, profile, and relationship data from external data sources (e.g. websites, databases, directories).

XDI4J

XDI4J is a java library for working with XDI.

• Higgins 1.1: XDI4j 1.1
