PDS Architecture
{{#eclipseproject:technology.higgins|eclipse_custom_style.css}}
This section describes the attribute and data related services, java frameworks and abstract data models that are used by many of the upper layers of Higgins solutions, services and applications.
Data Models
- The 1.1 version solutions listed below are based on the Context Data Model 1.1, a very generic, abstract, low level RDF-based model. It is our metamodel.
- For 1.1 we are now starting work on a higher level (more concrete model) that describes concrete attributes such as name, postal code, telephone number, etc. This model is called Personal Data Model 1.1 and is based on CDM 1.1.
IdAS Solution
The IdAS solution is a deployable "IdAS" Identity Attribute Service.
- Higgins 1.0: IdAS Solution 1.0: this solution provides 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) and expose them via the IdAS interfaces.

Attribute Service
New for Higgins 1.1, we're working on an network attribute web service called the Attribute Service. The initial protocol supported will be XDI with others to follow. See Higgins_1.1_Plan#Attribute_Service_1.1 for more info.
IdAS Proxy Service
- New for Higgins 1.1: See Higgins_1.1_Plan#IdAS_Proxy_Service_1.1
XDI4J
XDI4J is a java support library for working with XDI.
