XML is a wide standard to encode structured information. An XML file can contain the data, as in a database. Its primary purpose is to facilitate the sharing of data across different systems, particularly systems connected via the Internet. Languages based on XML e.g Geography Markup Language (GML), RDF/XML, RSS, Atom, MathML, XHTML, SVG, XUL, EAD, Klip and MusicXML are defined in a formal way, allowing programs to modify and validate documents in these languages without prior knowledge of their particular form.
Features
- Simultaneously human- and machine-readable format
- Heavily used as a format for document storage and processing, both online and offline.
- Manifests as plain text files, unencumbered by licenses or restrictions.
- Platform-independent, thus relatively immune to changes in technology.
- VB provides a comprehensive interactive and context-sensitive online help system
Weaknesses
- Difficult to apply in cases where bandwidth is limited e.g. Multimedia applications running on cell phones and PDAs which want to use XML to describe images and video.
- Uses the hierarchical model for representation, which is limited compared to the relational model.
- Interpretation sometimes involves additional work. There is no provision in XML, for example, for mandating that "2.13137" is a floating-point number rather than a seven-character string. Though some XML schema languages support this functionality.
