IDN evolution

From InterDataNet

Preliminary ideas and intuitions which led to the InterDataNet idea were formulated circa 2002 with COSA (Collaborative Operating System Architecture) in a set of MSc projects (listed in Pubblication Section). COSA focused on designing application-level protocols enabling collaboration between humans. While studying COSA allowed us to verify the interdisciplinary boundaries of its objectives, that view was constrained by being too technologically-constrained.

The problem boundaries were re-discussed in 2003 with Samuele Innocenti, M.Sc. thesis, specifying that the objects of the collaboration were documents. In that context the analysis targeted the requirements of public administrations. This research led us group to provide an abstract view of a preliminary document model. This document model was named Distributed Delocalized Document Information Model (D3IM) , while the architecture which was entitled to manage it was named Collaborative Information System Architecture (CISA).

Between 2004-2005, a more accurate definition of the D3IM was developed. This also enabled the IDN team to conduct preliminary implementation experiments and collaborations with interested public administrations as documented in 2006 M.Sc. reports. In early 2006, the need to place greater emphasis on the idea of a structured information model managed by a layered service architecture led to a further revision of the project idea boundaries.

The project was rebranded InterDataNet. Such name implied a transfer to the data realm, the equivalent of the internetworking capabilities in the computer realm. Interdataworking became a new project keyword.

InterDataNet’s main objective was specified as to provide an infrastructural approach to collaborative reuse, integration and application of data from multiple, distributed heterogeneous sources.

Those ideas did not gain consensus in the scientific community until they underwent another significant revision. In 2007, InterDataNet entered the world of “concepts” and began its metamorphosis. The project was boosted by two elements: confronting the InterDataNet Information Model with the graph-based data model of the Semantic Web (RDF), and revising the InterDataNet Service Architecture with Web approaches in mind (use of URIs, RESTful approach).

Almost simultaneously , the InterDataNet idea encountered the Linked Data and its grounding principles.

After one year of intense confrontation with the Web of Data, principles, solutions and approaches, InterDataNet is now entering a new phase, the one of the "Cooperative" data Web idea

If the Linked Data principles and solutions led to the Web of Data, the InterDataNet principles and solutions have the ambition to become the seed of the Cooperative data Web vision.
