SMW and Wikidata storage

Both systems use triples: subject, predicate and object
It's a girl revisited:

It's a girl!

The princess of cambridge was born on [[is born::2015-05-03]] 
Her rank inline to the throne is [[throne rank is::4]].
Her mother is [[mother is::Duchess Kate]].

SMW and Wikidata as databases?
	Compare to a relational database: Tables are dynamically created via SMW ask-queries e.g.List of Persons Wikidata SPARQL queries e.g Recent deaths in the royal family A page corresponds to a row in a table e.g. SMW Page Elizabeth II e.g. Wikidata entry Elizabeth II A property corresponds to a column in a table e.g. SMW Property Property:Person died e.g. Wikidata Property date of death

How SMWSync works

Self describing Properties
MetaModel, SiDIF, LinkML
Mapping SMW Properties to Wikidata properties
Command Line Tool

Self describing Properties

MetaModel, SiDIF, LinkML

ypgen --wikiId family --context FamilyContext --serve --host localhost

FamilyContext SiDIF is in legacy SiDIF triple format.

pyMetaModel mm_cmd command line tool will generate LinkML yaml markup and other target formats. LinkML can then generate even form format see:

pyMetaModel family example files

Mapping SMW Properties to Wikidata properties

# list of property mappings
# for family  versus wikidata

    smw_prop: label
  - arg: desc
    pid: description
    pid_label: description
