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:

SMW relational operations
   

Row and Column definition operations

Operation Manually Via Api Via Wikipush
Create create page and use markup to set property edit wikipush, wikiupload, wikirestore
Read visit link of page read html or markup {Done}} wikibackup, wikipush, wikiedit
Update modify page via edit edit wikiedit, wikirestore, wikipush
Delete delete page delete {Done}} wikinuke

Column value operations

How SMWSync works
  • Self describing Properties
  • MetaModel, SiDIF, LinkML
  • Mapping SMW Properties to Wikidata properties
  • Command Line Tool
   

{

Self describing Properties
   

{

BITPlanLogo2012 138x77.png
MetaModel, SiDIF, LinkML
YpgenScreenShotFamilyContext2023-04-19.png
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
- topic: Person
  prop_list:
  - pid: qid
    smw_prop: qid
  - arg: label
    pid: label
    smw_prop: label
  - arg: desc
    pid: description
    pid_label: description
    smw_prop: description
  - arg: died
    pid: P570
    pid_label: date of death
    smw_prop: died
  - arg: died_at
    pid: P20
    pid_label: place of death
    smw_prop: died_at

               [-e ENDPOINT] [--progress] [-p PROPS [PROPS ...]] [--proplist]
               [-pm PROPERTYMAP] [-pk PRIMARYKEY]
               [-pkv PRIMARYKEYVALUES [PRIMARYKEYVALUES ...]] [-t TARGET] [-u]
