Solution – Identity Problem

Get Yourself a Data Space that delivers:

A personal HTTP based ID (a URI)

Bind Your ID to an X.509 Certificate

Bind Certificate to your HTTP User Agents (e.g., Browser)

Bind Certificate to your Profile (e.g., a FOAF space).

Solution – Identity Problem Contd.

With the your HTTP ID in place you can then achieve the following:

Visit places on HTTP networks with no login and credentials repetitions (Intranet or Web)

Use ACL based policies to confine data access to specific groups of people.

Solution – Data Access & Integration

Use Middleware to generate Conceptual Views over Heterogeneous Data Sources using:

RDFizers to convert unstructured and semi-structured data to RDF.
