Extension:VisualData/de
VisualData is a full-fledged metadata management framework based on json-schema able to easily record, organize and query collection of data on your wiki.
It is characterized by a strong emphasis on the UI/UX side and aims to present itself as a lightweight or modern alternative to Semantic MediaWiki and Cargo.
Key-features
- Based on json-schema and slots
- forms and pop-up forms auto-generated from json-schema
- Integrated SchemaBuilder to easily create json-schema compliant schemas, with nested items and OOUI widgets
- Forms are validated with industry-standard ajv-validator
- SMW's style inline queries and result formats
- Can import/store/query large amount of data (with hierarchical structure) in specific articles/the entire wiki, and to rebuild them in minutes
- completed with an uninstall script: test the extension and opt-out if it doesn't meet your requirements!

UI-Elemente
The extension adds the following interface elements to your wiki (some of them only for authorized users and/or sysops)
- A sidebar section where to access all special pages offered by the extension
- The action tab "Edit data" by which to assign schemas to article and fill-in them through automatically generated OOUI forms
- and a namespace tab where to access the slot with json-data registered within an article through the extension
The visibility of each of them can be managed using the global parameters below.
Installation
- Download and place the file(s) in a directory called
VisualDatain yourextensions/folder. - Add the following code at the bottom of your LocalSettings.php

Bekannte Probleme
- in some MediaWiki versions and configurations, the ResourceLoader may generate syntax errors when bundling the Javascript files. In this case please use
$wgResourceLoaderDebug = true;in LocalSettings.php, this will include separately each file and should solve the problem. - rename of schemas and properties must be kept in synch with property and schema names hardcoded in parser functions. This will be solved implementing a query and form builder (see #Roadmap)
- queries require that the first printout exists, otherwise the row will not show. This could be solved using DUAL keyword
- the SchemaBuilder and the form processor do not yet support the directives
oneOf,anyOfand support for the$refkeyword
Roadmap
- handle visibility for content-blocks (Forms)
- handle visibility based on multiselect input widgets (check if has items)
- add
oneOf,anyOfandallOfsupport to form generator and SchemaBuilder (the SchemaBuilder will contain a select on the schema main panel) - add tuple and
$refkeyword to SchemaBuilder (properties panel, besides 'add field', 'add content block', etc.) - add additional properties to SchemaBuilder (additional panel)
- add query and form builder: this will store queries and forms as json schemas so that rename of schemas or properties can be updated within such schemas, not in the wikitext. The parser function will add queries and forms by their names or code
- UI for bulk-edit of json data in the BrowseData special page
Ajax navigation for datatables, SearchPanesand SearchBuilder
Additionally:
- version control for schemas and related data, so that edits of the schema constrain to the data related to the previous data structure
- version control notice shown through Extension:Echo and/or complying better design practice
- partial editing of schemas and field operations like Firebase's ArrayUnion, ArrayRemove, etc.
- preload json-ld/schema.org entities as json-schemas
- associate json-ld/schema.org vocabulary to user-defined schemas
