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

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
Operation | Manually | Via Api | Via Wikipush |
---|---|---|---|
Create | add property value manually on a page ✓ | ❌ | ❌ -> ✓ |

Modifying a Single triple
- py-3rdparty-mediawiki issue #91 wikiedit allow to modify single parameter of a macro WikiSon see WikiSon

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
- 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
Command Line Tool
usage: smwsync [-h] [-a] [--context CONTEXT] [-cpm CREATEPROPERTYMAP] [-d] [--dry]
[-e ENDPOINT] [--progress] [-p PROPS [PROPS ...]] [--proplist]
[-pm PROPERTYMAP] [-pk PRIMARYKEY]
[-pkv PRIMARYKEYVALUES [PRIMARYKEYVALUES ...]] [-t TARGET] [-u]
[--topic TOPIC] [--verbose] [-V]
Todos
- synchronization of complete entities or sets of properties (--all option for properties)
- detection of sync conflicts
- bidirectional sync
- publish to wikidata from smw
- GUI
- Sync dialog
- generation of smw topics and properties from wikidata
- mapping information in property definition page
- support of intext annotation
