NEPOMUK D6.1 - First version of the Backbone and Connector Infrastructure

NEPOMUK D6.1 - First version of the Backbone and Connector Infrastructure

Executive summary

The objective of this deliverable is to document a first starting point of the NEPOMUK architecture as well as the first prototype of the backbone and connector infrastructure. The pre-condition for the architecture is that it should lead to a basis for standardization efforts.

In order to achieve this, we applied the following methodical steps:

• We defined the terminology and investigated the technological background necessary for the envisioned Service-Oriented Architecture (SOA) of the NEPOMUK system.
• We reviewed the state-of-the art for Semantic Desktop implementations with respect of the underlying architectural principles.
• We identified the need for a NEPOMUK specific software engineering lifecycle, starting with a bottom-up approach.
• We designed the NEPOMUK backbone and connector infrastructure in a way that supports a later standardization of the architecture, by imposing a language and component neutral API and framework on the components and their communication.

The work resulted in the following:

• A starting point NEPOMUK architecture, which describes a first harmonized view on the early software services and components
• A backbone and connector infrastructure framework and API.
• Implementations of the backbone and connector infrastructure in the form of libraries. Firstly, a reference architecture using platform neutral web services infrastructure. Secondly, native implementations for specific platforms.
