Classification System Components: Classification Categories Taxonomy, hierarchy Metadata (Tags) Characterizes content Content Model Published set of classifications, metadata for a domain (e.g., eTMF) Content Classification System Discussion

Classification Categories Component Hierarchy of categories Categories, subcategories, content types Defined relationships with rules: Parent-Child All categories, content types required to have unique names and machine codes Each content type is associated with Metadata Properties (includes core and domain-specific) Content items are linked to content types. Unique classification and term codes based on Universal Decimal Classification System (UDC) numbering, widely used in libraries worldwide. Human and machine readable; infinitely expandable Can be described, edited and validated using OWL editor (like open source editor Protg) Supports any simple text vocabulary, including TMF Ref Model and other vocabularies W3C OWL2 and RDF/XML supported Classification Categories Component Study Digital Content Classification Categories Hierarchy

Metadata Component Used to tag or index digital content items Metadata Classes: Core - Comprised of four areas: File Properties, Classification, Audit Trail Business Process Domain-specific -- Metadata for a domain in life sciences such as eTMF, finance, legal administration, or others. Uses standards-based terms from groups like NCI Org Specific Metadata that meets organizations needs not standards based General obtained from public standards-based vocabulary terminology resources like dublin core Annotation Properties Metadata about classification categories and metadata: Core, Org-Specific metadata Metadata Component Core Metadata Example File Properties:

Content Model Component Contains classification hierarchy, metadata in machine readable format: Content Model Component

Term Sourcing Concepts: Terms adopted by standards bodies should be used first in eTMF model Primary Term Sources for eTMF Classification System: Internet Standards Dev Orgs : W3C, IETF, ISO, etc. Required for interoperability of machine code NIH NCIthesaurus: Term database for FDA, CDISC, HL7, other orgs Required for interoperability of clinical / health sciences data Secondary Term Sources for eTMF Classification System: Industry sources widely used terms in enterprise content mgmt software, TMF RM Classification System Term Sources *Spec, Table 6, p21

Classification Categories Component Classification hierarchy and numbering is based on UDC library numbering standard and XML naming Digital dot notation Designed for human and machine readability Each number is also a unique code for naming and ordering in the hierarchy Primary Categories (PC): Three digit. eTMF: 100-200 Subcategories (SC): Two digit: 10-99 Content Types (CT): : Two digit: 10-99 Maximum number of Sub- Category divisions is 5, excluding the 3-digits for the Primary Category [1] Per spec section 2.1.1; 6.0 Classification Categories Component Classification Categories Hierarchy and Numbering [1]: Hierarchy Numbering/Naming Considerations: Flexible, standards-based approach (W3C XML compliant naming*) Ability to add multiple hierarchy divisions / levels Proposed: 5 divisions = [100*90 5 ) = 5.9x10 11 Content Types Uniqueness of numbers usable as machine code identifiers Machine readable, human readable No sorting issues, no need for leading zeros*, no special chars *Leading zeros in XML syntax are ignored: http://www.w3.org/TR/REC-xml/

Numbering and Naming Scheme Numbering Primary Categories and Sub-Categories : Category Code number Content Type: Content Type ID Naming Primary Categories and Sub-Categories Simple text-based names Unique name, 64 char limit Abbreviation 16 char limit suggested Compatible with W3C XML naming standards : No special characters : ( ) ? / % # @ ! Classification Categories Component Example: Classification Categories Hierarchy, Naming, Numbering

Modifying Classification Category Entities General Editing Rules Domain Specific Classifications cannot be deleted > Reserve/Unreserve Modifications allowed to some annotation properties (see spec) Codes (Category Codes, CT Type ID) cannot be generated Organization Specific Classifications can be deleted Modifications allowed for classification metadata, annotations Codes (Category Codes, CT Type ID) can be generated Classification Categories Component Classification Category, Content Type Editing Rules* TypeImport TermsGenerate Code Add/ModifyDelete/Reserve Domain Specific YesNoNo/Yes**Reserve/Unreserve Organization Specific Yes Yes/YesDelete *Spec, Table 6, p21 **Annotation metadata

Classification Editing Tool Free, Open Source Protg (From Stanford University: http://protege.stanford.edu/ )http://protege.stanford.edu/ *Spec, Table 6, p21 Protg Editor: -Edit Classification Taxonomy and Metadata Terms -Validate Taxonomy and Term name compliance -Create valid RDF/XML Ontology

Proposed Classification System has following Properties: Based on Naming and Numbering that is W3C XML compliant No special characters: ( ) & # @ / etc. No leading zeros in classification numbers Based on Universal Decimal Classification (UDC) system for content classification: 100 199 : eTMF Domain UDC system used in 170+ countries worldwide; expandable, human and machine readable, sortable http://en.wikipedia.org/wiki/Universal_Decimal_Classification http://en.wikipedia.org/wiki/Universal_Decimal_Classification Flexible and customizable for organizations, yet interoperable Domain classifications Standardized; Organization-specific classifications Editable Defined set of rules for Editing, modifying Taxonomy Any Organization can Modify/Edit taxonomy using open source editors like Protg Classification Categories - Summary *Spec, Table 6, p21
