“ Wikidata is made up of "data items" which each relate to a single thing. For example, each author should have a data item, which will connect to every page about that author on any project via interwiki links, and a list of data statements with facts about the author (like date of birth) . Each data item has a unique Q-number ID ”

“ Works Works on Wikidata are split into two data items:
Work items: For the work in general. Edition items: For each specific version or edition. Each work should have a work item and at least one edition. There may be multiple editions on one Wikisource. Each language subdomain probably uses a different edition, which are all linked to the same work item. Wikipedia and most other projects will usually link directly to the work item, unless there is something of note about a given edition. ”

“ Each data item is made up of a label, a description, aliases, a section for labels and descriptions in other languages (based on templates on your talk page) , statements, and interwiki links. Practically, from Wikisource's point of view, each data item holds two important things: data statements and interwiki links.
Wikidata can be edited from Wikisource by utilising the WE-Framework gadget available through your Gadgets. The gadget when activated provides types of links to item types in the left toolbar, with a settings that will allows one to toggle on and off item types of interest. ”
