Wikibase is a software stack that allows storing linked data. Linked data is data that follows two principles.
Core to link data is the concept of semantic triples. In relational databases, data is stored in tables. Spreadsheet also use a tabular structure to capture data. A semantic triple, however can be seen as a statement.
The following record in tabular data |book title|author| |–|–| | The origin of species | Charles Darwin | can also be described as the following semantic triple in linked data
graph LR book[The origin of species] -- has author --> author[Charles Darwin]
The benefit of having the data as triples is that combining various datasets becomes straight forward. Combining our book table with the following data on the author.
|person||data of birth||birthplace|
|Charles Darwin||12 February 1809||The Mount, Shrewsbury, Shropshire, England|
graph LR book[The origin of species] -- has author --> author[Charles Darwin] author -- birthdate --> dob[12 February 1809] author -- birthplace --> bp[The Mount Shrewsbury, Shropshire, England]
When trying to merge the two tables a matching collumn between the two tables need to be defined and the columns
