Long data - like an event history; rows are variables, column has unit. Allows adding new variables without adding columns. Similar to rdf triples, 5th or 6th normal form dbms. Need to be able to reference registry of variables.
Machine-actionable - see https://ddialliance.org/taxonomy/term/198 “information that is structured in a consistent way so that machines, or computers, can be programmed against the structure.” [finish here 2022-05-18]
Maintainable (still used in DDI Lifecycle - like a database table of items that are maintained as a whole)
Major version
Minor version
Metadata - social science, behavioral definition
NADA cataloging tool - NADA is an open source microdata cataloging system, compliant with the Data Documentation Initiative (DDI) and Dublin Core’s RDF metadata standards. https://nada.ihsn.org/
N-Cubes - multi-dimensional data cubes used in DDI Codebook
Nesstar - even though it is a software, it is used for DDI
Physical record - physical recording of the values of the logical record
Population – a universe of unit types at a particular place and time (in some context).
questionnaire
Register - a list
administrative data that holds info that can do research on the subjects, eg, tax, births and deaths
Registry - catalogue that can find data, eg, SDMX
ISO/IEC 11179
Repository - place where data and metadata holdings are maintained and distributed, eg., an archive
representative variable
Resource package - in DDI Lifecycle, a special construction, not for a specific dataset
check to make sure it is still used
SDTL - [this should be in the acronyms list also] an independent intermediate language for representing data transformation commands (from III. Purpose in https://ddi-alliance.atlassian.net/wiki/download/attachments/860815393/Part_1_DDI-CDI_Intro_PR_1.pdf )
this is a DDI product, https://ddialliance.org/products/sdtl/1.0
series – use definition in DDI Lifecycle
statistical classification – add note on clarification of ‘statistical’ vs. other kinds of classification. Commonly hierarchical. Classification categories should be mutually exclusive and exhaustive at a given hierarchical level. Might be part of a group of classifications, maintained as a series of official versions. See usage in XKOS, CDI, Lifecycle, and GSIM.
study - (noun) In DDI, this is the set of information related to a data activity, including data and metadata, design, etc. May cover several related data files/datasets, surveys, methods, etc. Used as an organizing principle for packages of data and metadata.
survey - (noun) Preferred usage: a data collection activity that involves a sample (sampling some population). NOTE: Recognize that has multiple uses in DDI corpus, e.g. to mean a questionnaire. Cambridge dictionary: survey (noun) - an examination of opinions, behaviour, etc., made by asking people questions: ‘A recent survey found/revealed/showed that 58 percent of people did not know where their heart is.' (need to research how it is used in specs)
unit of measurement - used in DDI (CDI, codebook?, lifecycle) at instance variable level. attribute of variable. defines a reference system for quantifying measurements to understand what is comparable. has a quantity kind (e.g. length, count, mass, area…); quantity kind is related to operations that are valid (e.g. area has perimeter)
unit type – generic for subject of observation. ‘unit of analysis’-- specialized from sampled feature (in O&M terms…
). universe – given a unit type, a universe is the domain of those ‘units’ that is observed. e.g. a unit type might be ‘humans’ and a universe might be ‘humans who are nurses’. A population is a universe at a given place and time.
