In order to clarify my previous email I have prepared this functional
taxonomy of the elements that in my opinion form an item:
Meta
+ Labels
-- Multilingual main label (no sources, no qualifiers)
-- Multilingual alternative labels (no sources, no qualifiers)
-- Multilingual historic/alternative labels (will be possible with
monolingual datatype+qualifiers)
-- External identifiers (currently treated as statements)
-- Sitelinks (how each project calls the concept)
+ Metainformation
-- Concept taxonomy (part of/ subclass of)
-- Concept life-cycle (sometimes irrelevant, other times expressed with
start/end date, no deprecation possible)
-- Concept precedence (possible to express as statements "succeeded
by"/"preceded by", but perhaps needs disambiguation from content)
-- Concept dependence (endemic to, bound to [experience/cognition/etc],
recognition methods, etc)
-- Source for the concept (not defined, sometimes irrelevant)
Content
+ Current information
-- Statements
+ Historic information
-- Deprecated statements
+ Open data information
-- Related to outcome on RFC about open datasets
