TASK DESCRIPTION
As a developer working with Wikidata, I want the entity data to not consume
too much network traffic.
As someone hosting Wikibase instances, I want the entity data to not consume
too much storage space.
**Problem:**
The JSON serialization of each statement contains a `"type"` field, which
always has the value `"statement"`, wasting 19 bytes per Statement (before
compression). The field used to be necessary back when Wikibase distinguished
between Claims and Statements, but it has been hard-coded to always contain
`"statement"` since 2015 (Wikibase DataModel Serialization 1.4.0).
**Example:**
$ curl -s https://www.wikidata.org/w/api.php -d action=wbgetentities -d
ids=Q12345 -d props=claims -d format=json -d formatversion=2 | jq
.entities.Q12345.claims.P1050[0]
{
"mainsnak": {
// ...
},
"type": "statement",
"id": "Q12345$1d677e6e-4bad-e489-bda8-7a0bd8ec38c0",
"rank": "normal",
"references": [
// ...
]
}
**Acceptance criteria:**
- API responses do not contain a `"type"` field for Statements (note: they
must still contain a `"type"` field for data values!)
- Stored contents of new revisions do not contain a `"type"` field for
Statements (how to check
<https://wikitech.wikimedia.org/wiki/User:Lucas_Werkmeister_(WMDE)/How_to_get_the_raw_text_of_a_page_or_revision>)
- Non-goal: we do //not// update stored content of existing revisions.
NOTE: Like T217431 <https://phabricator.wikimedia.org/T217431>, this is
technically a breaking change that should be properly announced.
