Notes and links[edit]

Data Model of Citation[edit]

See (bottom of)

  • UUID
  • Citation Target (pointer to bibliographic metadata, during transition contains wikitext)
  • Target Anchor
  • Citation Origin
  • Origin Anchor

Example Citation Object:

        uuid: 12399392929
        target: {
            resource: wikidata item or uri or plain old wikitext, for legacy support
            anchor: difficult! needs to be robust, depends on type of resource. See Hypothesis project
        origin: {
            resource: wiki page name or id  --> can be turned into a URL
            anchor: difficult! some kind of offset? <-- two anchors next to each other might compete with other ideas

Made available via the MediaWiki web API for every revision of a page.


  • Do we need qualifiers for the type of citations (eg. critques, agrees with)? -> see CiTO Ontology
  • Has to be resistant against editing.

Existing inline citations {{#cite:PMID:234939}} will be surrounded by an anchor:

It is a function not a template: Compare {{cite|PMID:123}} and {{#cite:PMID:123}}

Wikitext references would stay as they are (with a wrapping template):


For consumers of the data more structure is an advantage.

from the 123 etherpad:

  • UUID #UUID-identities citation object. generated on demand. do we need this in wikitext?
  • Citation target (URI) #bibliographic database object /or/ wikitext (with templates/parameters)
  • Target Anchor #chapter, page, etc. This is optional, but can only come from the wikitex
  • Citation origin (URI) #Wikipedia page specific revision
  • Origin anchor #point or range. some kind of offset

How to refer to a source?

  1. You can use items to store a reference <-- scalability problems
  2. You can link to a statement (but the references may change and suddenly not support a claim) (or even be "imported from: $language Wikipedia")
  3. You can link to a reference to a statement <-- a bit controversial
  4. Reusing a reference is an indicator that a reference should be converted to an item.
There are claims that can be sourced with references that already have an item (es. "Italy has this list of regions" <-- source: QCONSTITUTION OF ITALY (QConstitution of Italy))

Cultural problems:

Treat all citations the same?

How do the statics change when Wikidata community decides that something is notable or not.

If source is not notable, they won't be items, and won't show up in certain statistics.

References should lead you somewhere. The ones in Wikidata are actionable and the ones as <refs> don't. Creating two types of references.

A possible solution would be to have a separate Wikidata for citations and references that can "discuss" with Wikidata proper and other sources repositories ( = Librarybase?)

Who would maintain it (access, maintainance, policies, ...)?
Who or what would fill in the necessary data? Will we need to found a new community?

Blast from the past: <-- a much more restrictive RfC we had in the past about setting up a new namespace (with different rules) for RELIABLE sources
