Study Notes
Understanding Markup Languages
- Markup alters text appearance and formatting, creating document structure and meaning for output mediums.
- Composed of codes or tags added to text for modifying appearance or meaning.
- Word processors utilize one or more markup languages for formatted text.
- Markup Languages are categorized into Specific and Generalized Markup Languages.
Development of Generalized Markup Languages
- Dr. C.F. Goldfarb introduced a technique in the 1970s for universal text description across applications.
- Proposed that markup should focus on structure rather than formatting.
- Suggested that both humans and software should easily read code adhering to strict syntax.
- These ideas culminated in the creation of SGML, officially adopted as a standard in 1986 by ISO.
SGML and XML
- SGML allows specifications for character sets, enhancing document comprehension by processors.
- XML was developed as a smaller, more web-optimized language derived from SGML.
- XML supports hyperlinking, data interchange formats, and is utilized for web data management.
What is XML?
- XML provides a standardized method to describe any type of data, making it versatile with different development tools and platforms.
- Designed for data storage while preserving useful information.
- Facilitates a standard approach to describe, capture, process, and publish information.
XML vs. HTML
- XML emphasizes the separation of form and content, while HTML focuses mainly on display formatting.
- XML is extensible, allowing users to define custom tags for specific applications, unlike the fixed tag set of HTML governed by W3C.
XML Structure
- Consists of a logical structure, an XML declaration, and follows specific syntax rules.
- Must have a root element, elements must close properly, tags are case-sensitive, and attribute values require quotation marks.
XML Benefits
- XML is widely used and enhances data separation from HTML.
- It simplifies data sharing, transport, and platform changes, increasing data availability.
- Supports the development of new internet languages, such as XHTML, WSDL, and RSS.
Disadvantages of XML
- Relies heavily on the author; inconsistent processing can occur.
- XML setup can be complex and costly.
Characteristics and Additional Benefits of XML
- XML is characterized by simplicity and self-describing features.
- Open and extensible, XML promotes application independence and integrates various data formats.
- Facilitates one data source presenting multiple views and supports internationalization.
XML Technology and Applications
- XML is applied in content management, web services, and protocols like RSS, emphasizing its practical utility in the digital world.
Rules of XML
- Elements must feature closing tags, tags must be case-sensitive, and the structure must be properly nested with a singular root element.
- Attribute values must be enclosed in quotes, adhering to standards for valid XML documents.
