return to Introduction

Following this Introduction, this discussion paper is organized as follows:

Section 2, Architectural Views: Presents and describes in detail the DIDO Architecture as a set of components collected into complementary Architectural Views: Stakeholder, Technical, and Taxonomic.

• The Stakeholder View is organized in accordance with the communities considered to be the “customers” of the DIDO RA, e.g., Platform, Domain, and Ecosystem.
• The Technical View is organized into two basic views: Fundamental (e.g., System of Systems, Assurance, Tools) and Node Network.
• The Taxonomic View is organized into four taxonomies: network topology, network access control, nodes, and data.

Standards (technical and de facto) relevant to or associated with the components supporting each view are listed.

Section 3, Governance: Proposes and describes the elements of the Governance structure to manage the DIDO Architecture as an Open Source program, i.e., Charter (for the effort as a whole plus each of the DIDO COIs), Policies & Procedures (P&P), and Guide (plain English version of the P&P).

Section 4, Requirements: Lays the groundwork (models and methods) with which to specify, assess, manage, implement, and govern DIDO requirements to ensure well governed DIDO Implementations. Describes in detail the functional and non-functional requirements one must consider during the requirements specification process for DIDO platforms and then how to assess the resulting requirements specifications.
