SMWCon Fall 2012: Architectural Knowledge Management with Semantic MediaWiki
0 likes834 views
This document discusses using Semantic MediaWiki to manage architectural knowledge for Dutch e-government. It describes how NORA, the overarching e-government architecture, defines principles that are then refined and applied in domain-specific "daughter" architectures through a system of interlinked semantic wikis. Impact analysis and tracking application of principles across wikis is enabled through tools like the NORA Dashboard.
SMWCon Fall 2012: Architectural Knowledge Management with Semantic MediaWiki
- 1. Architectural Knowledge Management with Semantic MediaWiki Remco de Boer (ArchiXL) SMWCon Fall 2012 Thu, Oct. 25 Köln, Germany 1
- 2. ArchiXL • IT / Enterprise architecture consultancy • Founded in January 2008 • Located in Amersfoort (NL) • Focus on financial and public sector • Independent • Knowledge areas: – IT architecture (BPM, EAI/SOA, ECM, IDM, BI, Portals) – Enterprise architecture methods, techniques and tools (TOGAF, ArchiMate) – Knowledge management (semantic wikis) – Domain knowledge (insurance, pension funds, local government, education) 12-11-2012 2
- 3. Today’s agenda • Background: e-government • Architectural knowledge in the Dutch e-government • Using SMW to manage Dutch e-government architectural knowledge • Reusing Architectural Knowledge through a system of wikis – Linking different semantic architecture wikis • NORA Dashboard – Analysis through remote queries 3
- 4. Background: ‘e-government’ • Goals (for citizens and businesses): – Reduce administrative burdens – Better service provision • Means (for government agencies): – Work together – Align business processes – Use each other’s information • This has huge impact on the enterprise architecture of government agencies! – business processes – information landscape – technology 4
- 5. Example: the environmental permit • Suppose you want to renovate and extend your house • It’s a big operation, so you need to fell some trees that are in the way • You also need to demolish part of the existing building 5
- 6. Renovating your house, before Oct. 2010 Building permit Tree felling permit Demolition permit 6
- 7. Renovating your house, since Oct. 2010 Environmental permit 7
- 8. Interacting with the e-government 8
- 9. The NORA architecture family • Establish processes and systems that ensure interoperability • Increasing level of specificity (government domain organization) • Main constituents: – Architecture principles – Architecture models • Architecture is the fundamental organization of a system embodied in its components, their relationships to each other, and to the environment, and the principles guiding its design and evolution (ISO-IEC 42010) • “Principles are general rules and guidelines, intended to be enduring and seldom amended, that inform and support the way in which an organization sets about fulfilling its mission.” (TOGAF) 9
- 10. Example architecture principles • No wrong door: – Citizens and businesses can direct their questions to ‘the government’; government offices (re)direct to the appropriate service • Single request, multiple use of data: – Once the government has obtained certain data from a citizen or business, no government agency may ask for the same data again. • Transparent services: – Citizens and businesses are informed about the state of the requested service. 10
- 11. Principle (Wiki page) 11
- 12. Statements in NORA 12
- 13. Statements: core attributes • Page name: a condensed form of the statement that uniquely identifies it (e.g. “No wrong door”). • Type: the type of statement – e.g., ‘Driver’, ‘Goal’, ‘Basic principle’, ‘Derived principle’, ‘Requirement’ • ID • Statement: The full statement, in the form of a sentence • Rationale: The reason behind the statement • Implications: The implications of the statement • Realizes: References to other statements that are realized through this statement. – E.g. “No wrong door” realizes “Findable (consumers can easily find the provided services)”. 13
- 14. Reusing Architectural Knowledge: A System of Wikis 14
- 15. Recall the NORA architecture family • Principles from NORA are (re)used and refined through the NORA daughters • Interesting issues: – NORA evolves; how do the NORA daughters assess the impact? – Question: how are the NORA principles actually being applied? 15
