NeoWiki turns wiki pages into queryable structured data

Schemas, infoboxes, relations, and Cypher, native to MediaWiki.

This is a public demo of NeoWiki, an early-stage MediaWiki extension. Explore the examples below, edit anything you like (it is a sandbox and resets periodically, so you cannot break it), and tell us what works and what is missing via the issue tracker or by contacting Professional Wiki.

Just exploring

Structured data, queried in a page: Museum collection runs live graph queries over linked museums, artworks, and exhibitions.
Several Subjects on one page: open the Data tab on Rijksmuseum to see the museum and its yearly visitor records as separate Subjects.
Every Subject is shaped by a Schema, and Layouts control how Subjects are displayed.

Trying it hands-on

Edit through a form and watch it update live: Subject views shows one Subject in three layouts at once, with edits propagating between them.
See how a Schema constrains data, with required fields, value ranges, and formats: Validation Demo.
Create your own: start any page, then use "Create subject" in the NeoWiki section of the sidebar.

-NeoWiki turns your wiki into a collaborative graph database by letting you store and query structured information.
-Information is stored in versioned document form inside of wiki pages. The latest version is also stored in
-graph databases via which it can be queried.
-NeoWiki is in the experimental proof of concept phase. It is not production ready, public interfaces will change,
-big structural changes will happen, and key functionality is still missing.
-This demo exists to gather feedback to inform further development. ([https://professional.wiki/en/contact Contact Professional Wiki])
-You can find [https://github.com/ProfessionalWiki/NeoWiki/tree/master/docs technical documentation] in the
-[https://github.com/ProfessionalWiki/NeoWiki NeoWiki git repository].

+This is a public demo of NeoWiki, an early-stage MediaWiki extension. Explore the examples below, edit anything you like (it is a sandbox and resets periodically, so you cannot break it), and tell us what works and what is missing via the [https://github.com/ProfessionalWiki/NeoWiki/issues issue tracker] or by [https://professional.wiki/en/contact contacting Professional Wiki].

-'''As a reader:'''
-* View a Subject: [[Professional Wiki]]
-* View a Schema: [[Schema:Company]]
-'''As an editor:'''
+== Start here ==
-* Edit a Subject: [[Professional Wiki]] (login required)
-* Edit a Schema: either via a Subject using it, i.e. [[Professional Wiki]], or directly on the Schema page, i.e. [[Schema:Company]]
-* Create a Subject: TODO
-'''As a developer:'''
+'''Just exploring'''
+* Structured data, queried in a page: [[Museum collection]] runs live graph queries over linked museums, artworks, and exhibitions.
-* View Subject JSON: [[Special:NeoJson/ACME_Inc]] (developer UI, normal users will not see JSON. [https://github.com/ProfessionalWiki/NeoWiki/blob/master/docs/SubjectFormat.md View docs])
+* Several Subjects on one page: open the Data tab on [{{fullurl:Rijksmuseum|action=subjects}} Rijksmuseum] to see the museum and its yearly visitor records as separate Subjects.
-* Query the graph database: [[Cypher|Cypher raw example]]
+* Every Subject is shaped by a [[Special:Schemas|Schema]], and [[Special:Layouts|Layouts]] control how Subjects are displayed.
-* [[#REST_API_endpoints|Explore the REST API]]
+'''Trying it hands-on'''
-== Demo pages ==
+* Edit through a form and watch it update live: [[Subject views]] shows one Subject in three layouts at once, with edits propagating between them.
-* Simple page with automatic infobox and edit form: [[NeoWiki]], [[ProWiki]]
+* See how a Schema constrains data, with required fields, value ranges, and formats: [[Validation Demo]].
-* Subject with relations: [[Professional Wiki]]
+* Create your own: start any page, then use "Create subject" in the NeoWiki section of the sidebar.
-* Multiple subjects per page: [[ACME Inc]]
-* Wikibase Statement emulation: [[Berlin]]
-* Displaying data from other pages: [[Company Infoboxes]]
-* [[Reactive UI example]]

-'''Schemas''' allow you to define the structure of your data. For instance, you can define that a Employee has a
