  1. Foundational Objects

  2. Areas of coverage • Technical objects • Foundational objects • Lessons learned from review of Use Case content • Simple Study • Simple Questionnaire • First level extensions (Codebook content…)

  3. Technical Objects • Identification, versioning, reference, etc. • Structures for strings • Structures for dates • Structures for controlled vocabularies • Etc.

  4. What is “Foundational” • Objects required as basic parts of more complex constructions • Concepts, universes, categories, data element/represented variable • Objects required for high level search and discovery • Citation, abstract, contents, coverage, etc.

  5. Is it foundational?(could be a candidate) • High level process metadata • Requirements for the process (inputs) • What the process entailed • Who did it • When was it done • Criteria for completion • Results (outputs) • Organization and Individual information and relationships

  6. Foundational Object Characteristics • KISS principle: Keep it simple stupid • A Foundational object should have enough content to relay full basic useful information for a simple use case • Structured to serve as a base for extension • Extension adds more detail to support more complex use cases

  7. Review of Use Cases • Discovery information for metadata AND data file • Citation • Abstract • Coverage • Temporal (reference date and related subject) • Topical (subject and keyword) • Spatial (description) • For spatial search engines (bounding box, spatial object, lowest level and geographic date) • Collection content • What things make up a study and how do they relate to each other

  8. Review of Use Cases (cont.) • Provenance • Who owns it • Where is it from • How did it change • Actors, Events, Objects • Who can access, how and when

  9. Review of Use Cases (cont.) • Simple data file • Variable • Name • Physical Location • Data type • Representation (valid and invalid-missing) • Source • Concept • Universe

  10. Review of Use Cases (cont.) • Simple questionnaire • Population • Universe • Sample (frame, methodology, management) • Question • Intent • Text • Response domain • Sequencing (simple) • Concept

  11. Simple Case: Simple Study • Description of a simple data set tying together the following content: • Data item (label, location, data type, etc.) • Basic discovery information • Universe • Concepts • Code lists

  12. Simple Case: Simple Questionnaire • Description of a simple questionnaire covering: • Simple questions (question intent, text, response) • Non-complex question flow • Information on the population responding to the questionnaire (universe, sample, weights, methodology, etc.) • Concepts

  13. First Extension:Scope of the Codebook Case • Elements most commonly used from existing profiles • CESSDA • ICPSR • IHSN • This is for the description of a simple study • First level extension from fundamental objects
