Wikimedia Enterprise це новий міжвідомчий проєкт Фонду Вікімедіа. Мета проєктк — створення сервісів для великомасштабних комерційних користувачів контенту Вікімедіа. Раніше цей проєкт був відомий як «Okapi»

The focus is on organizations that want to repurpose Wikimedia content in other contexts, providing data services at a large scale, so that they are faster and more comprehensive, reliable, and secure. Wikimedia Enterprise aims to improve the user experience of Wikimedia's readers beyond our own websites; increase the reach and discoverability of the content; and improve awareness and ease of attribution and verifiability by the organizations that reuse Wikimedia project data the most—through self-funding services.

There is a very high barrier to entry for using Wikimedia data, outside of the common use cases of reading or editing. This is because the content is hard for machines to segment and understand, which in turn affects how far Wikimedia project data reaches beyond our own ecosystem, and the scale of impact it can have.

In the Movement Strategy recommendations to increase the sustainability of our movement and improve user experience there are the recommendations to, respectively: "Explore new opportunities for both revenue generation and free knowledge dissemination through partnerships and earned income—for example...Building enterprise-level APIs," and "Make the Wikimedia API suite more comprehensive, reliable, secure and fast, in partnership with large scale users.... and improve awareness of and ease of attribution and verifiability for content reusers."

It is well known that a few massive companies use our projects' data. Those companies recognize that without the Wikimedia projects, they would not be able to provide as rich or reliable an experience to their own users. There has long been a feeling among community members that these companies should do more to reinvest in the Wikimedia communities for the benefits they gain from the content and resources they use.

This led to the idea of developing a new approach that is more sustainable in the long term and provides a much clearer relationship between Wikimedia and enterprise users. Most financial benefit for Wikimedia would likely only come from a very small handful of heavy for-profit users, and would feed back into the Wikimedia movement.

As this idea developed, it became clear there is a responsibility to democratize our data for organizations that do not possess the resources of these largest users, to ensure we are leveling the playing field and helping to foster a healthy internet without reinforcing monopolies. The benefits of such a service shouldn't just be for startups or alternatives to the internet giants, but also for universities and university researchers; archives and archivists; along with the wider Wikimedia movement.

Wikimedia Enterprise’s focus is on businesses that reuse our content, typically at a large scale—e.g., integrated into knowledge graphs, search, voice assistants, maps, news reporting, community tools, third party applications, and full-corpus research studies. Augmenting Wikimedia's many datasets to put structure behind our unstructured content will allow all our content reusers to meet their individual requirements while also setting us up to build new tools and services in the future, available to everyone. Reusers of our content are looking for three critical components:

  • Frequency: Regular current snapshots of Wikimedia projects
  • Reliability: Dependable, accessible infrastructure
  • Quality: a “best last revision”

Emphasizing a self-funding set of specific use cases allows the Wikimedia API team to focus on volunteers, teams, and organizations looking to access (and, most importantly, interact with) our data sets. This includes the majority of community editing tools, which will be out of scope for this service. For more information on improvements to the existing Wikimedia APIs see the service page on the "API Gateway" initiative.

Program Goals:

  • Content: Make more of our movement's content available in consistent machine-readable formats, freely available for all researchers and re-users.
  • Resource-load: Reduce the need for high-intensity site-scraping by the highest-frequency and highest-volume reusers, which currently target our production servers.
  • Fundraising: Provide a clearer and more consistent way for the largest re-users to reinvest derived benefits back to the movement, instead of making occasional altruistic donations that vary in size.

Following are the introduction paragraphs for a much more detailed Community essay.

The full essay covers the following topics

Libre and Gratis are the two meanings of “free,” commonly phrased as free as in speech, or free as in beer.

Wikimedia projects are, have always been, and will always remain libre. The principles of free cultural works mean that anyone can use Wikimedia without restriction, including commercially. As a movement, we embrace this. It is why we reject ‘non-commercial’ licenses, as they would limit the kinds of reuse possible. And it is why we consider commercial reuse an important means of distributing knowledge to audiences.

Equally, Wikimedia projects are, have always been, and will always remain gratis. The ability to freely access the knowledge available across all Wikimedia projects has always been core to the mission of the Foundation and the movement. We provide this access not only to individuals visiting our websites but also programmatically to machines so that our content can be repurposed in other environments. The full corpus of Wikimedia content always has been, and will continue to be, made available for reuse in various forms (including but not limited to database dumps, APIs, and scraping) at no cost.

As a result, our content is often repurposed by for-profit organizations that rely on it to support their business models, and which consequently earn revenue from it. Outside of voluntary corporate donations to the Wikimedia Foundation, the movement has never received benefits from any of this revenue through return investment. In acknowledgement of this, under the heading of Increase the sustainability of our movement the Movement Strategy process asked the Wikimedia Foundation to explore, among other things, “enterprise-level APIs...models for enterprise-scale for-profit reusers, taking care to avoid revenue dependencies or other undue external influence in product design and development.” Furthermore, under the heading Improve User Experience, a further recommendation stated, "Make the Wikimedia API suite more comprehensive, reliable, secure, and fast, in partnership with large scale users where that aligns with our mission and principles, to improve the user experience of both our direct and indirect users, increase the reach and discoverability of our content and the potential for data returns, and improve awareness of and ease of attribution and verifiability for content reusers."

The Enterprise project team is developing a new resource aimed at for-profit content reusers, who have product, service, and system requirements that go beyond what we freely provide. Use of this offering will not be required for for-profit content reuse; companies can continue to use the current tools available at no cost. All Enterprise API revenue will unequivocally be used to support the Wikimedia mission—for example, to fund Wikimedia programs or help grow the Wikimedia Endowment.

This project represents a new kind of activity at the Foundation. The project is at a very early stage that should be considered a learning period. We will have successes, we will make mistakes, and we will need to adapt our strategies. The team is committed to listening, engaging, and where possible, integrating the feedback we get on our work. This document is organic and is reflective of the team's current thinking; we are attempting to document as much work as possible in the open. Up until now, our work has been shaped by a series of initial interviews with community members, Wikimedia Foundation Board and staff, researchers, and reusers.

Given the nature of the service, primary decision making for it will rest with the Wikimedia Foundation. We are seeking community input, in particular from the technical community and those who have been involved in the strategy process, throughout the lifetime of the service. Technical feedback has been gathered from colleagues at the Wikimedia Foundation, industry and research partners, technical partners across the movement, and with the broader technical communities via Phabricator. Input into the funding development side of the service will follow a similar pattern. We will continue gathering input via research interviews and focus groups, as well feedback here on Meta as per our principles.

Over time, the "product" being offered will grow and improve. We are still defining the exact nomenclature for API endpoints and documentation, but these are the main products that our team is currently building. This information is accurate as of Version 1.0.

Structured Content API

High-volume reusers that use an infrastructure reliant on the EventStream platform depend on services like RESTBase to pull HTML from page titles and current revisions to update their products. High-volume reusers have requested a reliable means to gather this data, as well as structures other than HTML when incorporating our content into their KGs and products.

Wikimedia Enterprise Structured Content API, at release, will contain:

  • A commercial schema
  • SLA

Firehose API

High-volume reusers currently rely heavily on the changes that are pushed from our community to update their products in real time, using EventStream APIs to access such changes. High-volume reusers are interested in a service that will allow them to filter the changes they receive to limit their processing, guarantee stable HTTP connections to ensure no data loss, and supply a more useful schema to limit the number of api calls they need to make per event.

Enterprise Firehose API, at release, will contain:

  • Filtering of events by Project or Revision Namespace
  • Guaranteed connections
  • Commercially useful schema similar* to those that we are building in our Structured Content API and Bulk API
  • SLA

*We are still in the process of mapping out the technical specifications to determine the limitations of schema in event platforms and will post here when we have finalized our design.

Bulk API

For high volume reusers that currently rely on the Wikimedia Dumps to access our information, we have created a solution to ingest Wikimedia content in near real time without excessive API calls (Structured Content API) or maintaining hooks into our infrastructure (Firehose).

Enterprise Bulk API, at release, will contain:

  • 24-hour JSON*, Wikitext, or HTML compressed dumps of "text-based" Wikimedia projects
  • A hourly update file with revision changes of "text-based" Wikimedia projects
  • SLA

*JSON dumps will contain the same schema per page as the Structured Content API.


To obtain access to the Enterprise API datasets, there are three methods: *Paid **Realtime API (Batch and Streaming) Through the dedicated Enterprise API product website at *Free **Snapshot API An update of the Enterprise API data is provided for all every two weeks at **Snapshot API + Realtime (Batch) Via Wikitech:Portal:Data Services, available to anyone with a Wikimedia cloud services account.
