Move legend and namespace note into a standalone notations.drawio file
shared across all figures. Regenerate Step 6 figures with stacked
datatype property boxes (UML-like) matching the Step 5 style, instead
of separate connected nodes.
Ontology overview diagram shows all tm: classes, object/datatype
properties, schema:/org:/skos: external classes, subClassOf
relationships, and namespace color coding using Chowlk notation.
Example subgraph diagram shows Irene Abendroth instance data with
representative memberships, migrations, relationships, and places.
Includes Chowlk library for draw.io.
SPARQL CONSTRUCT queries transform graph-05 into graph-06 using the tm:
vocabulary. Persons keep schema:Person properties, works become
org:Membership, professions become schema:Occupation, enumerations
become skos:Concept with tm: subtypes. Split 010-occupations into two
query files (passthrough + retype). Includes step-06 binary, Rakefile
tasks, and example data for Irene Abendroth.
SPARQL UPDATE queries add standard vocabulary properties alongside
existing custom predicates: schema:Person/Place/Organization types,
schema:givenName/familyName/birthDate, owl:sameAs for authority links,
wgs84:lat/long for coordinates, skos:Concept/prefLabel for enumerations,
and rdfs:label for persons.
Use W3C Organization Ontology for work engagements (org:member,
org:organization). Profession instances become schema:Occupation.
Custom properties (workLocation, employmentType, etc.) are kept
with updated domains/ranges.
Add namespace prefixes (rdfs, migrants, person, personp, work, workp,
location, locationp) to query files. Use --prettify in Rake tasks so
example files use abbreviated IRIs. Fix 2hop task to use graph-02.
SPARQL queries to list classes and properties, and src/schema.rb
CLI to run them against any graph file. Includes bundler/setup
for compatibility with Ruby 4.0 without bundle exec.
19 queries in updates/ convert categorical columns (continent, country,
city, gender, profession, etc.) from literals to typed RDF objects with
rdfs:label. map/step-02.rb applies them to produce data/graph-02.ttl.
Also fix step-01.rb to sanitize column names with spaces and avoid
prefix serialization issues with fragment IRIs.
