Knowledge Management inside Alfresco

  1. 1. KM inside ECM From content to knowledge Ronny Timmermans January 29, 2013 12009 - Proprietary and Confidential Information of XeniT Solutions
  2. 2. Concept of a document -> evolving• Document = Memory Container – Comes from the Paper Age . – Paper culture was not about “sharing”.• Some problems – It contains (“unstructured”) natural language – Format often linked to Functionality • Ppt, Excel, Doc • format dictates our model often – Atomic -> Check out• ECM & – -> document is a black box – -> Adds context & Governance 2010 - Proprietary and Confidential Information of XeniT Solutions
  3. 3. Reason for existence of ECM? • Find to reuse, verify, learn, .. • Different types: – By search – By browse – By discovery • What do we need? – Common vocabulary (language) – Common model 2010 - Proprietary and Confidential Information of XeniT Solutions
  4. 4. Model? Mental Model• Contains your business concepts• Qualities of a good model: – Shared – Explicit – Evolving – Rich • Real World is complex • RDBMS is simple • Documents are rich, but lack structure (= conventions) • Natural language? 2010 - Proprietary and Confidential Information of XeniT Solutions
  5. 5. Alfresco’s technical Meta-Model• Meta-data? Meta-Model!• The trouble with document types• Reuse: http://www.omg.or g, … etc etc• Sharepoint? ING? 2010 - Proprietary and Confidential Information of XeniT Solutions
  6. 6. Dimensions of Search• I want google like search?• Use: – Context – Author / Who – Time – Place (geo) – Business concepts like • Project • Customer • Case• We are designing a search space• How we design can evolve in time 2010 - Proprietary and Confidential Information of XeniT Solutions
  7. 7. The navigation space• Often despised (for being redundant with meta-data), but – Tree = Intuitif – It’s flexible • Personal • Evolves• By containment, a folder expresses common knowledge about the content inside• Challenge: The tree orders different dimensions at different levels. • Per customer, per year, per phase, .. • Do we have conventions?• Alfresco: – Adds a description (not just a container icon) – Allows subtyping – -> Folder becomes a business concept (meta-model) – XeniT Fred : Dynamic folders. All children of the “multiple views” idea. 2010 - Proprietary and Confidential Information of XeniT Solutions
  8. 8. Document types• A document is “of a type”• Governs the meta-data• But? – Is it? Grey zone of 80% – Is the document of a “type”, or are the enclosed entities? – Mix-in types – aspects 2010 - Proprietary and Confidential Information of XeniT Solutions
  9. 9. Categories• Non-meta-data based classification • Often complementary to document types• Often linked to templates (content boilerplates)• Maybe we want to have & type&category tree? 2010 - Proprietary and Confidential Information of XeniT Solutions
  10. 10. Aspects• What is it? – Aspect oriented programming – Customer, email, project, … – Nice innovation from• Dynamic• Flexible part of the model• Allow for ‘kind of’ multi-inheritance 2010 - Proprietary and Confidential Information of XeniT Solutions
  11. 11. Tags, folksonomy• Flexible !• Need to organise, refine 2010 - Proprietary and Confidential Information of XeniT Solutions
  12. 12. Faceted Search• Self-service Search• Suggests what you want to find• Exposes data in the repository• Best usage: show these lists already when filling in meta-data 2010 - Proprietary and Confidential Information of XeniT Solutions
  13. 13. Today … We have Multiple Stores• ECM• CRM• WIKI• ..• How to handle? – Make sure we don’t increase search chaos• Classical solution: – shift a layer in front = the mental model. • Portal solves this? Portal = application integration, not information integration approach. – We seldom simplify 2010 - Proprietary and Confidential Information of XeniT Solutions
  14. 14. Some best practices• Use an explicit model to input, and the same model to retrieve – ex: categories• Self contained documents• Use the context to simplify operations – e.g. when you search or create• Pick low hanging fruit – favorites – History : last 10 documents – faceted search – Grouping & filtering – Link to content• Organize collaboration around central concepts – (see “share” in JIRA tickets) – We often start from the system, the tool, not the concept 2010 - Proprietary and Confidential Information of XeniT Solutions
  15. 15. Trends• Semantic web – Semi-structured – Look inside the content• Visualise complex information – Size of folders in navigation structure – Colour of folders• Big data ? (did I forget the cloud )? – NoSQL more than Big DATA is interesting, because dynamic.• Cut content to (interesting) pieces – Reuse• Interesting pointers – http://semantic-mediawiki.org/ – www.mike2.org – Alfresco & Stanbol (apache) : EU project 2010 - Proprietary and Confidential Information of XeniT Solutions
