Convert MediaWiki to Properties

Why Convert MediaWiki to Properties?

Converting MediaWiki markup to Properties format is useful when you need to extract structured content from wiki pages and transform it into key-value pairs for application configuration or internationalization purposes. Wiki pages often contain structured data in tables, infoboxes, and template parameters that can be mapped directly to property keys and values for use in Java applications and other systems that consume Properties files.

MediaWiki markup, created for Wikipedia in 2002, uses a rich syntax including headings marked with equals signs, bold text with triple apostrophes, internal links with double square brackets, and templates with double curly braces. This structured content can be parsed and converted into flat key-value pairs where headings become key prefixes, table data becomes individual properties, and template parameters map naturally to property entries.

The Properties format is the standard configuration file format in the Java ecosystem, supported natively by java.util.Properties and used extensively in Spring Boot, Apache Maven, Gradle, and other Java tools. By converting wiki documentation into Properties files, you can create configuration files, internationalization bundles, or data dictionaries from collaboratively maintained wiki content, bridging the gap between documentation and application configuration.

This conversion is especially valuable for teams that maintain configuration documentation on internal wikis. Instead of manually transcribing settings from wiki pages into properties files, automated conversion ensures accuracy and consistency. It also enables a documentation-first workflow where configuration values are authored and reviewed in a wiki environment before being exported as Properties files for deployment.

Key Benefits of Converting MediaWiki to Properties:

• Configuration Extraction: Extract settings from wiki documentation into usable config files
• i18n Support: Convert wiki translations into Java internationalization bundles
• Data Portability: Move structured wiki data into application-ready format
• Automation Ready: Properties files integrate easily into build pipelines
• Java Ecosystem: Native support in Java, Spring, Maven, and Gradle
• Simple Format: Easy to read, edit, and manage key-value pairs
• Documentation Bridge: Connect wiki-based docs to application configuration

Practical Examples

Example 1: Wiki Configuration Page to Properties

Input MediaWiki file (config.wiki):

== Database Settings ==
{| class="wikitable"
|-
! Key !! Value
|-
| database.host || localhost
|-
| database.port || 5432
|-
| database.name || myapp_prod
|}

Output Properties file (config.properties):

# Database Settings
database.host=localhost
database.port=5432
database.name=myapp_prod

Example 2: Wiki Translations to i18n Bundle

Input MediaWiki file (translations.wiki):

== English Translations ==
* '''greeting''' — Hello, welcome!
* '''farewell''' — Goodbye, see you later!
* '''error.notfound''' — Page not found
* '''error.unauthorized''' — Access denied
* '''button.submit''' — Submit Form

Output Properties file (messages_en.properties):

# English Translations
greeting=Hello, welcome!
farewell=Goodbye, see you later!
error.notfound=Page not found
error.unauthorized=Access denied
button.submit=Submit Form

Example 3: Wiki Application Settings

Input MediaWiki file (app-settings.wiki):

== Application Configuration ==
{{Infobox software
| name = MyApp
| version = 2.5.1
| author = DevTeam
}}

=== Server Settings ===
* '''server.port''' = 8080
* '''server.context-path''' = /api
* '''server.ssl.enabled''' = true

Output Properties file (application.properties):

# Application Configuration
app.name=MyApp
app.version=2.5.1
app.author=DevTeam

# Server Settings
server.port=8080
server.context-path=/api
server.ssl.enabled=true

Frequently Asked Questions (FAQ)

Q: What is MediaWiki markup?

A: MediaWiki markup is the wiki markup language used by Wikipedia and thousands of other wikis powered by MediaWiki software. It was created in 2002 and uses special syntax like == for headings, ''' for bold text, '' for italics, [[ ]] for internal links, and special table syntax. It is designed to be easy to learn while supporting rich document formatting for collaborative content creation.

Q: What is a Properties file?

A: A Properties file (.properties) is a simple text-based configuration format used primarily in Java applications. Each line contains a key-value pair separated by an equals sign (=) or colon (:). Lines starting with # or ! are comments. Properties files are used for application settings, internationalization bundles, and environment-specific configuration in Java, Spring Boot, and many other frameworks.

Q: How is structured wiki content converted to key-value pairs?

A: The converter parses MediaWiki markup and extracts structured content. Wiki table rows become individual key-value entries, headings are used as key prefixes for grouping, template parameters map to properties, and list items with clear key-value patterns are extracted. Plain text paragraphs are typically stored under content-based keys or section identifiers.

Q: Will wiki formatting be preserved in the Properties file?

A: Properties files are plain text key-value pairs and do not support any formatting. Wiki formatting such as bold, italic, links, and headings is stripped during conversion. The focus is on extracting the textual content and structured data from the wiki page. If you need to preserve formatting, consider converting to HTML, Markdown, or another rich format instead.

Q: Can I use the resulting Properties file in Spring Boot?

A: Yes! The generated Properties file follows standard Java Properties format and works seamlessly with Spring Boot's application.properties, message bundles for i18n, and any other Properties-based configuration. You can place the file in your src/main/resources directory and Spring will automatically load it.

Q: How are wiki templates handled during conversion?

A: Wiki templates with named parameters are converted into property entries where the template name becomes a key prefix and each parameter becomes a separate property. For example, a template with name=MyApp and version=1.0 would become app.name=MyApp and app.version=1.0 in the Properties output.

Q: What encoding does the output Properties file use?

A: The output Properties file uses UTF-8 encoding for maximum compatibility with modern applications. Traditional Java Properties files used ISO-8859-1 with Unicode escape sequences for non-Latin characters, but since Java 9, UTF-8 Properties files are fully supported. Most modern frameworks handle UTF-8 Properties files without issues.

Q: Can I convert Properties back to MediaWiki?

A: Yes, the reverse conversion is also possible using our Properties to MediaWiki converter. The key-value pairs can be formatted into wiki tables, lists, or structured pages. However, since Properties files don't contain formatting information, the resulting wiki page will need manual formatting adjustments for optimal presentation.
