The Database
Rule 1: The Information rule
All information in the database is to be represented in one and only one way, namely by values in column positions within rows of tables.
BigTable
★ Schema-free databases
★ Name-value pairs
★ Keys ➠ URIs
★ Relations ➠ HyperLinks
★ No SQL unfortunately?
★The era ofinformationrepositories
★ Storage of documents instead of records
★ Relations through hyperlinks
★ Dynamic or non-relational schemas
★ Weak, if any, typing
★ Focus on findability and storagability rather than on schema adherence
★ Shift from database to data modelling
★ Increasing importance of the domain model
★ Semi-structured information
★ Content- and information rather than website or document management
1. Domain Modelling
2. ‘External Classification’
Two challenges
Domain Modelling
★ wireframes★ navigation hierarchy★ landing pages★ lists of things★ which content will fit where
★ ‘UML’-like domain model★ content★ structure★ which content can be shown where
★ domain model
★ define and name entities, content parts and characteristics
★ define and establish relationships★ think about findability★ think about unit of manipulation★ think about access control
External Classification
Labelling
Classification
The Universal Taxonomy
Run!Run!Run!
★ the universal taxonomy fails
★ single-rootedness★ things appear in multiple locations★ omphaloskepsis: navel gazing
multi-labeling
tagging
taxonomies ➠ folksonomies
➠
➠
★ folksonomies
★ tags and optional tag bundles★ content- rather than
classification-driven★ user generated micro-content★ shown as tag clouds
★ user generated micro-content
★ represents a genuine value★ must be moderated★ history falsification★ spam (PR whoring, p0rn)
★ lower the doorstep★ no authentication required★ QA burden for content owner
Drip feeding
success factors★ volume★diversity★reward
impediments★ when a formal classification is
required★ expert communities★ classification ~ structure
★ when full-text searching is a viable alternative★ use tags to define weight in ranking
Discovery
★ the doom of simplicity
★ natural language processing
★ plurals
★ typos
★ abuse-prone
★ no upfront expectation management
★ upfront knowledge
★ managed expectations
★ principle of least astonishment

Conclusions
Organisation★ Always make a thorough judgment as to
where to store what
★ RDBMS for relational data
★ Repositories for documents/information
★ Integrate instead of standardization
Classification★ Rich metadata improves findability and (re)
usability
★ Somewhat-typed metadata
★ Tagging, folksonomies r k3wl, but
★ Business case needed
★ Don’t forget menial tasks
Discovery★ Premature feedback doesn’t exist
★ Classification can add influence ranking
★ K I Simple !

CCGC★ Problem
★ 10 x 10 x 10 x 10 = 10.000★ 20 x 20 x 20 x 20 = 160.000★ ...
CCGC★ Solution
★ Hierarchical Structure Widget
★ Store hierarchy in XML document
★ Provide authoring and editing widget for hierarchy

CCGC
CCGC★ Lessons learnt
★ think critically about metadata
★ the system might need adaptation (or the data)
★ focus on domain model rather than on the ‘website’
