Partial RDF dumps
Open, LowPublic


Implement options for the RDF dump script to only dump a pre-defined set of entities (given on the command line or in a file, or by limiting the type of entities to dump).

In addition to the entities given explicitly, any properties used in describing the entities should be automatically included in the dump.

A list of entities is very different than limiting it by the type of entities. Once this bug is taken up it should be first split into two.

In addition to the entities given explicitly, any properties used in describing the entities should be automatically included in the dump.

What about other linked items in statements?

I wonder if this is still worth pursuing. Is there demand for it? What are the concrete usecases it's serve?

Giving the speed at which the dump grows, we need to look into this again.

I'd suggest splitting (at least the nt dump as I work mostly with those and therefore have an opinion on that side) in the following:

  1. Triples regarding properties (where the property is the subject)
  2. Triples that contain language information (aka the labels)
  3. The "pure" direct triples

In case someone works with those, I think it's reasonable to assume they just need one of those dumps, or are able to combine them. Not sure however how much of that is already done (I think property-triples (1.) aren't in the nt dump atm anyway, are they?)

These types of dumps should be considered:

  1. Dump of all labels
  2. Dump of all descriptions
  3. Dump of all aliases
  4. Dumps of all labels in a specific language
  5. Dumps of all descriptions in a specific language
  6. Dumps of all aliases in a specific language
  7. Dump of all terms (optional)
  8. Dumps of all terms in a specific language (optional)


  1. Dump of all sitelinks
  2. Dumps of all sitelinks in a given wiki
  3. Dumps of all entities with sitelinks in a given wiki


  1. Dump of all statements
  2. Dump of all truthy statements
  3. Dumps of all statements for a property
  4. Dumps of all truthy statements for a property
  5. Dumps of all entities with statements for a property


  1. Dump of all page properties (wikibase:statements, wikibase:sitelinks)

Users may easy to make a custom dump by combining several types of dumps above.
