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
